    Mushrooms: Darker fruiting bodies in cold climates

    In nature, specific colors and patterns normally serve a purpose: The eye-catching patterns of the fire salamander convey to its enemies that it is poisonous. Red cherries presumably attract birds that eat them and thus disperse their seed. Other animals such as chameleons use camouflage coloring to protect themselves from discovery by predators.

    But climate also plays a role in coloration: Especially insects and reptiles tend to be darker in colder climates. Cold-blooded animals rely on the ambient temperature to regulate their body temperature. Dark coloration allows them to absorb heat faster.

    The same mechanism could also play a role in fungi, as the research team of Franz Krah, who wrote his doctoral thesis on the topic at TUM and Dr. Claus Bässler, mycologist at the TUM and coworker in the Bavarian Forest National Park suspect. Mushrooms might benefit from solar energy to improve their reproduction, as well.

    To test their theory, the researchers combed through vast volumes of data. They investigated the distribution of 3054 species of fungi throughout Europe. In the process, they analyzed the lightness of their coloration and the prevailing climatic conditions in the respective habitats.

    The results showed a clear correlation: Fungal communities have darker mushrooms in cold climates. The scientists also accounted for seasonal changes. They discovered that fungal communities that decompose dead plant constituents are darker in spring and autumn than in summer.

    "Of course, this is just the beginning," explains Krah. "It will take much more research before we develop a comprehensive understanding of mushroom colors."

    For example, further seasonal coloring effects cannot be detected in fungi that live in symbiosis with trees. "Here, other coloration functions, such as camouflage, also play a role."

    The researchers also need to study the degree to which dark coloration influences the reproductive rate of fungi.

    Aivan grows headphones from fungus and yeast

    Fungus, yeast-based bioplastic and other materials grown by microbes have been used to make the Korvaa headphones, designed by Finnish studio Aivan in collaboration with scientists.

    All up, the Korvaa headphones feature six different microbially grown substances. They were designed to showcase the potential of the technology known as synthetic biology, or "synbio" for short.

    The team chose headphones because of the variety of materials they contain — from hard plastic to pliable mesh and leathery soft textile.

    The rigid plastic frame of the headphones is a petroleum-free bioplastic grown using the lactic acid in baker's yeast (scientific name saccharomyces cerevisiae). This polylactic acid (PLA) polymer is biodegradable and can be used for 3D printing, which is how the Korvaa component was fabricated.

    The padding that sits over the ears is produced by a fungus called trichoderma reesei, dubbed "nature's strongest bubble-maker" by the team at Aivan.

    It grows cells into the air, making a foaming protein called hydrophobin. Synbio researchers mix it with plant cellulose to keep the structure stable, though soft.

    Covering the foam is mycelium — the branching, root-like part of a fungus that has elsewhere been used for clothing and architecture. In this case, the fungus is phanerochaete chrysosporium, and it has a leathery texture that is meant to sit comfortably on the ears.

    Headphones also require a mesh-like cover for the speakers. In Korvaa, this is provided by a microbially produced protein based on spider silk, one of the toughest substances in nature. The biosynthetic version of the silk used here can also make bulletproof vests.

    Synbio researchers collect the fine fibres into a larger structure using electrospinning, in which a negatively charged extrusion tip shoots the material onto a positively charged plate.

    Other parts of the headphones are cellulose — the primary structural material in plants, but produced faster by microbes and enzymes — and a cellulose-mycelium composite.

    In their current form, Korvaa won't replace anyone's trusted set of headphones. They are purely a concept that explores the future of product design.

    "For now, certain compromises had to be made," said Aivan product designer Saku Sysiö. "However, it's a rapidly developing field of research and we're excited to see what happens in this area in the next years, and the implications for various industries, how these materials are used."

    A Mushroom that Lives Solely on Plastic Has Been Discovered

    Add one more strange and awesome plastic-killing discovery to the list: A rare mushroom that feasts on plastic. According to reports, the mushroom's plastic-devouring properties were first discovered in 2011, when a team of Yale undergraduates and their professor traveled to Ecuador for a research trip.

    They found the mushroom - Pestalotiopsis microspora - in the amazon and were astounded to find that the fungus not only subsists on polyurethane, but could do so without oxygen.

    That means it could be planted at the bottom of landfills and happily eat its fill of plastic for eons to come. It's the first plant to sustain itself merely on plastic.

    1.5-meter diameter mushroom found in SW China

    A 0.7-meter tall mushroom with a diameter of 1.5 meters and perimeter of 4.1 meters was found by a villager in Jianshui County in southwest China's Yunnan Province.

    Wang Fengying said she found the fungus under a cluster of wild roses on Friday morning when she went up a mountain to look for wild mushrooms.

    "It is moisture-rich and looks milky white on the front," Wang said, adding that it takes three people with outstretched arms to form a circle around the mushroom.

    From afar, the fungus looked like a small hill. Local villagers have fenced it with a shade net and opened an umbrella for it.

    "Judging from pictures, I think the mushroom is a Tricholoma," said Hua Rong, an expert at the Kunming Institute of Edible Fungi.

    Tricholoma is a kind of large fungus which is found mainly in tropical areas. Edible and nutritious, it tastes slightly sweet and delicious, Hua added.

    State of the World's Fungi 2018

    The facts and figures contained in the pages of the 2018 State of the World’s Fungi report and this website will probably come as a total revelation to many people.

    The first of its kind outlining the state of the world’s fungi, the report and associated website highlight just how important fungi are to all life on Earth.

    It is clear that Fungi should definitely be viewed on a par with the plant and animal kingdoms and that we have only just started to scratch the surface of knowledge of this incredible and diverse group of organisms.

    What also becomes apparent is that when looking for nature-based solutions to some of our most critical global challenges, fungi could provide many of the answers.

    Host Defense Mushrooms: Smart Natural Intelligence Fungi Products

    Host Defense is a brand that is founded on the potential mushrooms have on different aspects of health. What makes mushrooms, primarily mushroom mycelium, potentially effective is their ability to not only aid in human health, but also nourish the environment that it flourishes in.

    Both of the creators behind Host Defense, Paul Stamets and C. Dusty Yao have a combined passion for mushrooms. While the former has invested over 40 years of time as a mycologist and has since written six books on mushrooms, the latter focused more on herbal extractions. Together, they were able to bring Host Defense Mushrooms to life.

    Overall, Host Defense appears to stick to the claims made. That is, using an array of mushrooms to heal humans and the environment. On the human aspects of things, each dietary supplement is unique in terms of the type of mushroom used.

    Some supplements contain a single mushroom, while others are a combination. For instance, the CordyChi is a blend of cordyceps and Reishi, and when combined, both are believed to support stress, and fatigue reduction.

    What gives Host Defense a competitive advantage is their reliance on just mushrooms and its different components (i.e. mycelium and other nutrients from within). This is ideal, as it elevates the effectiveness of a formula while ridding hindrances additional ingredients may have.

    Shitakes seeded in China sprouting as “Product of the USA”

    Lou Caputo Jr., fresh mushroom sales director, said there is clear evidence of a clever plan by the Chinese to dump fresh Shiitake mushrooms into this market. And, in the process, wipe out all U.S.-based competition.

    Caputo said his company’s local competitor, Oakshire Mushroom Farm, went out of business in late December. The publication Lancaster Farming reported that among Oakshire’s problems, “a big increase in imported Chinese spawn logs was eating into Oakshire’s side business selling to other growers.”

    Caputo said Chinese spawn logs are being shipped in ocean containers to Philadelphia at prices below what his family’s spawn logs cost.

    The big twist is that the Chinese logs are loaded with spawn “and are ready to burst” with a budding Shitake mushroom crop within days after the product is delivered by the containerload to customers who once bought from domestic producers. Because the logs’ crop is harvested in the U.S., the mushrooms are labeled as “Product of the USA.”

    Perhaps no one in the U.S. knows with certainty how the Chinese spawn logs are produced. But, because no chemicals are used in the days before the U.S. harvest, the Chinese Shitakes are sold as organic, Caputo said.

    Caputo doesn’t have the resources to investigate the Chinese spawn log business. He has gathered that there are many small-volume individual Chinese producers of these logs selling to a major exporter. But he knows that no oak trees grow in China. He questions what’s in the logs and who in China provides food-safety oversight or organic certification on the products. The logs have a registered import code of “live spawn” and “wood product.” There is no export notation of shipping fresh organic Shitake mushrooms.

    The Pennsylvania Department of Agriculture reports that the Spotted Lanternfly, which is an invasive planthopper native to China, India and Vietnam, was discovered in Berks County and has spread to other southeastern Pennsylvania counties, which include Chester County and Kennett Square. “This insect has the potential to greatly impact agricultural crops such as grapes, hops, and hardwoods,” the state ag department said.

    Caputo has no proof of a connection. But he notes the Spotted Lanternfly’s appearance in Pennsylvania generally coincided with the arrival of China’s first spawn logs.

    Caputo noted that Chinese Shitakes are apparently a different strain of mushroom than his, because the Chinese product has a room temperature shelf life of a couple of weeks. Caputo wonders how such a product was bred.

    The Chinese product is being sold by one Texas retailer at $12 for five pounds. “The Shitake fresh market was $3.50 to $4 a pound two years ago,” Caputo noted. He added that Chinese prices have recently inched up now that just one U.S. competitor remains business.

    'Non-charismatic' fungi's future under threat

    Fungi may not be "cute and cuddly", but rare species should still be protected from extinction, a research scientist says.

    Landcare Research scientist Peter Buchanan, a mycologist or fungi expert, has helped organise the first workshop to get Australasia's most endangered fungi on the International Union for Conservation of Nature's red list of threatened species.

    "Humanity has a temptation to over-value and prioritise conservation of the colourful, cute and cuddly, and ignore other less charismatic forms of life," Dr Buchanan said.

    "Yet life on this planet cannot exist without the so-called 'non-charismatic majority of biodiversity.' "

    The workshop, held in Melbourne next week, will examine about 100 species of fungi from New Zealand, Australia and New Caledonia, and evaluate their chances of survival to see if they belong on the red list.

    Dr Buchanan said making it onto the red list would give fungi a better chance of survival.

    "Getting the fungi onto the list will mean global as well as New Zealand and Australian recognition from the government and public that we need to value and conserve our fungi as well as our plants and animals."

    Until 2014, only three species of fungi were on the red list, despite fungi being "the second largest kingdom of life after the animal kingdom".

    In comparison, 10,570 plants and an even larger number of animal species are on the list.

    In about 2010, several mycologists decided to raise awareness that a variety of fungi are threatened with extinction due to habitat loss, pollution, over-harvesting and global warming - the same factors that affect the survival of other plants and animals.

    Dr Buchanan said the rarity of fungi was challenging to assess because they could be invisible beneath soil, wood, or leaves when in their feeding stage.

    "We typically only notice them when they reproduce and we see their fruiting bodies, including mushrooms, brackets, puffballs, or smaller fruiting bodies within spots on leaves."

    A Chanterelle By Any Other Name

    Golden chanterelles are on are throughout the region, visible from a distance with their bright yellow caps. While all fresh chanterelles are delicious, our favorite patch yields dense, chunky specimens with a ghostly white – rather than yellow – stem and false-gilled underbelly. We call these firm and meaty culinary gems ‘white back’ chanterelles, though my hunch is they are Cantharellus phasmatis, first documented in 2013 at University of Wisconsin-La Crosse.

    Annual Humongous Fungus Festival in Crystal Falls, Friday and Saturday

    The 28th annual Humongous Fungus Festival in Crystal Falls is this weekend. This festival celebrates the largest continuous mushroom in the world which spans nearly 38-acres between Crystal Falls and Alpha.

    Beginning on Friday there will be a parade down Superior Avenue and live music at night.

    To fit the 'Psychedelic 60s' theme there will be free tie dying. The events continue on Saturday with a flea market, mushroom cook-off and live music.

    "We're just really excited. This is such an interesting and unique event and so this is something we hope that lots of people will come to. It's a great tourism event for Crystal Falls and so we want people to be shopping with our local businesses and enjoying the recreational opportunities Iron County has to offer,” said Iron County Chamber of Commerce Chamber Director Erika Sauter.

    Mushroom-foraging experts will lead mushroom hunts on Saturday. Registration is required for the guided forages.

    Start-up plans to bring mushroom products to the world

    In 2007, Vân went to a meditation class to improve her mood. That’s when she was introduced to mushroom floss – a vegetarian food full of flavour and nutritional value.

    Vân asked for the recipe and cooked it for her family. She even made some as gifts for friends and neighbours, who encouraged her to start her own business with homemade mushroom floss and became her first customers.

    Good news travels fast. The orders flooded in and Vân and her mother had to work until midnight to produce enough mushroom floss.

    The problem was that they did it all manually.

    “We had to tear mushrooms’ stem into fibres to make the mushroom floss. The job took hours to complete and it was painful,” she said.

    Looking down at her swollen fingertips, Vân understood that it was time to make a change.

    Fyffes spends €36.6m on Canadian mushroom deals

    Tropical fruits group Fyffes spent €36.6 million last year buying Canadian mushroom companies, expanding a business that it entered into in 2016.

    The consideration for acquisitions in western Canadian, comprising the Prairie Mushroom group of companies and 4 Season King Mushrooms, was contained in the 2018 annual report of Fyffes, recently filed with the Companies Registration Office.

    Fyffes, best known for its banana, melon and pineapple distribution operations, ventured into the North American mushroom business in April 2016 through its acquisition of Canadian producer Highline Produce in a deal that was worth the equivalent of €97.7 million at the time. It followed up months later with the €40 million purchase of another Canadian firm, All Seasons Mushroom.

    Fyffes itself was taken over by Japanese conglomerate Sumitomo in early 2017 in a €761 million deal, ending its 35 years on the Irish stock market.

    Is Paul Stamet's product line specifically Lion's Mane supplements a scam since it uses only mycelium?

    I thought he was the goto mushroom guy. I want to give him the benefit of the doubt that he knows what he's doing but I'm skeptical.
