#085: Schizophyllum commune, the Mushroom With Over 28,000 Sexes [Archived]

Note: This is an archived post. Read the current version of this post here. Commonly known as the Split Gill, this little mushroom is easily distinguished by its small gills, which appear to be split lengthwise. The Split Gill is a notable mushroom because of its unusual morphology, ecology, and genetics.  Before I get into the bizarre world of fungal sexes, I would like to describe the physical characteristics of this distinctive mushroom.

#072: Leucocooprinus birnbaumii, The Yellow Houseplant Mushroom

This small, yellow, parasol mushroom is a tropical species but can be found throughout the world in greenhouses and indoors among potted plants. These mushrooms often surprise people by appearing suddenly indoors at any time of the year.  birnbaumii is a mostly harmless mushroom.  It does not damage your plants at all, but it should not be eaten.  The Yellow Houseplant Mushroom is mildly poisonous, but symptoms appear only when it is eaten in large quantities.  If you are worried that a pet or child may eat the mushrooms, then you may want to pick the mushrooms and throw them out.  This will not get rid of the fungus, so you will have to check the pot regularly.  The mushrooms may also spread to other pots in your house through airborne spores.  If you want to get rid of them forever, then you will probably have to throw away your...

#071: Flammulina velutipes, The Velvet Foot [Archived]

Note: This is an archived post. The current version of this post is available here. This edible mushroom can be found in specialty markets under the names “Enokitake” and “” It can also be found in the wild in temperate areas across the Northern Hemisphere, but the wild mushrooms look nothing like the cultivated versions.  Flammulina velutipes has many common names, including: Velvet Foot, Enokitake, Enoki, Winter Mushroom, Velvet Stem, Velvet Shank, Golden Needle Mushroom, and others.  I am using the name Velvet Foot because it is among the most commonly used names and it sounds the most poetic.  According to Wikipedia, Enoki is the Japanese name for the Chinese Hackberry Tree, a tree in the hemp family on which F. velutipes is often found.  Thus, “Enokitake” means “Chinese Hackberry Tree Mushroom.”  Wikipedia also says that the Chinese names for this mushroom translate to Golden Needle Mushroom or Golden Mushroom. ...

#070: Ganoderma applanatum, The Artist’s Conk [Archived]

Note: this is an archived post. You can find the current version here. Ganoderma applanatum is unique among fungi in that it is primarily used by humans as an artistic medium. This large, woody bracket fungus features a flat, rapidly-staining, white pore surface, which readily becomes a natural canvas for an artist.  By lightly scratching the pore surface, an artist can produce beautiful sketches without using a pen, pencil, or paint.  The pores stop growing once the mushroom is removed from its substrate, so the stains remain on the pore surface.  Conks produced by applanatum are woody and therefore decay very slowly.  As a result, artwork produced on the Artist’s Conk can last for many years when kept indoors.

#069: Amanita muscaria, Part 1: The Type Mushroom [Archived]

Note: This is an archived post. You can find the current version of this post here. You are undoubtedly familiar with this mushroom, even if you recognize neither its scientific name, Amanita muscaria, nor its common name, “The Fly Agaric.” If the word “mushroom” does not immediately bring this fungus to mind, then the word “toadstool” probably does.  You have certainly encountered Amanita muscaria’s distinctive red cap with white spots in a wide variety of visual art forms.  This toadstool frequently pops up in paintings, cartoons, video games, movies, and decorations.  It is because of the artistic over-use of the Fly Agaric that I referred to it above as “The Type Mushroom.”   When describing a new taxonomic division or species of fungi, mycologists collect a “type specimen” which best exemplifies the characteristics of that taxon.  This ensures that future mycologists know exactly what the original author intended to include in...

#068: Frosty Pod Rot Disease of Cacao Trees

Frosty Pod Rot, caused by the fungus Moniliophthora roreri, is one of the most significant pathogens of cacao trees (Theobroma cacao). The disease has been around a long time: it was first recognized in Ecuador in 1917 and first described in 1933.  roreri likely evolved in Columbia, where the greatest diversity of the species is located and where cultivated cacao trees grow near closely related trees.  Up until the 1950’s, Frosty Pod Rot was limited to northwestern South America.  Since then, it has spread throughout Central America and into Peru and Venezuela.  In these areas, Frosty Pod Rot is the most destructive cacao disease, resulting in the loss of about 30-40% of total production.  The disease has not yet made it to Asia or Africa, where most of the world’s chocolate is produced, but it may just be a matter of time.

#065: Trametes versicolor, the Turkey Tail [Archived]

Note: This is an archived post. Read the current version of this post here. It is easy to see how this mushroom got its common name: the upper surface of the fan-shaped fruiting body sports rings of color that vary from gray to brown to reddish orange. In fresh specimens, the edge of the mushroom is white, making it look remarkably like the displayed tail of a wild turkey.
