Fungus Fact

#230: Lichenomphalia umbellifera

Nearly all lichens belong to the Ascomycota, but there are some lichenized basidiomycetes (often called “basidiolichens”)… and a few of those actually form mushrooms!  Lichenomphalia umbellifera is a lichen that forms a small agaric.  If you find this mushroom, you would probably dismiss it as just another LBM, unless you notice the lichen at its base.  The lichen part of this mushroom consists of tiny green bubbles that seem to be sprinkled over its substrate.  You’re most likely to find L. umbellifera in the Pacific Northwest – just remember not to overlook the small mushrooms!

News Update

2018 Fall and Winter Fungal News Update

Fungi appear in the news with surprising frequency. However, many of those stories do not provide any new information. Below is a summary of news stories that have taught me something about fungi from September through December 2018. Read each summary to learn about: zombie ants, mushroom poisonings, White Nose Syndrome, Bananas, and more.

Fungus Fact

#085: Schizophyllum commune, The Mushroom with Over 28,000 Sexes

If you think dating is complicated in the human world, be glad you’re not Schizophyllum commune.  Humans have two basic biological sexes and six or more gender identities to deal with, but S. commune has to choose from over 28,000 different sexes!  This overly complex system is based on genetics and the weird way fungi reproduce.  But this isn’t just a weird example, it’s also one of the most common mushrooms in the world.  You can probably find the mushroom out now, and identify it easily.  The little white mushroom is easily distinguished by its small gills, which appear to be split lengthwise.  This unique feature has led to its common name, the “Split Gill” or sometimes “Common Split Gill.”

Sphaerobolus ingoldii 0

Fungus Fact

#122: Sphaerobolus stellatus, the Artillery Fungus

Sphaerobolus stellatus has one of the most unusual spore dispersal mechanisms: its base pops up and quickly flings a glob of spores into the air. The fungus forms tiny (no more than 3mm across) star-shaped mushrooms in mulch, which can cause problems for homeowners when the spore globs glue themselves to cars, siding, and the like. S. stellatus’s unique spore dispersal strategy has resulted in a variety of common names, including: “Artillery Fungus,” “Cannonball Fungus,” “Cannon Fungus,” “Sphere Thrower” (which is a literal translation of its Latin name), and “Shotgun Fungus.”

Omphalotus illudens 1

Fungus Fact

#007: Omphalotus illudens, The Jack-O-Lantern Mushroom

If the spirit of Halloween were a mushroom, it would be Omphalotus illudens. This agaric is commonly known as the “Jack-O-Lantern mushroom” for a few good reasons. First, it is bright orange, like the pumpkins that decorate doorsteps all over the United States in October. Not only is the cap orange, but so are the gills, the stipe, and the interior. Second, the mushroom’s gills glow in the dark, especially when they are young and fresh. Furthermore, the mushroom often has a sweet smell and is poisonous. Nothing says Halloween like something that is orange, glows in the dark, smells sweet, and has a sinister side.

Fomes fomentarius 4

Fungus Fact

#189: Fomes fomentarius, The Tinder Polypore

Fomes fomentarius is the Swiss army knife of the mushroom world: it has a variety of uses that are important in many different contexts. It is used by survivalists, fly fishermen, and even some hat makers. Although it isn’t edible, the mushroom is considered medicinal. Humans have used F. fomentarius for well over 5,000 years (more about that later) and probably much longer than that. The polypore grows from dead or dying trees and is shaped like a slightly irregular horse’s hoof. It has a variety of common names, which is not surprising when you consider its many uses. The two most widely used names are “Tinder Polypore” and “Hoof Fungus.”

Reindeer Moss 1

Fungus Fact

#171: Reindeer Lichen

Reindeer Lichens grow in northern temperate forests, boreal forests, and even in the tundra. They are highly branched, fruticose lichens that are a primary food source for reindeer (also called caribou in North America). These lichens are sometimes called “Reindeer Moss,” even though they are lichens and not moss.

Chlorociboria cups 1

Fungus Fact

#166: Chlorociboria spp., Green Stain Fungi

Chlorociboria spp. include some of my favorite fungi. Although you don’t see their mushrooms very often, it is quite common to find pieces of wood that have been stained blue-green by Chlorociboria mycelium. This attractive and unusual coloration earned these fungi many common names, including “Green Stain Fungus,” “Blue Stain Fungus,” “Turquoise Elfcup,” and various combinations and derivatives of those. I enjoy finding the stained wood, especially during dry periods or over the winter, when mushrooms are scarce.

#156: Calvatia gigantea, the Giant Puffball 1

Fungus Fact

#156: Calvatia gigantea, the Giant Puffball

This mushroom certainly lives up to its name!  The largest Calvatia gigantea fruiting body on record was 8ft 8in in diameter and weighed 48 pounds!  Normally, the “Giant Puffball” forms mushrooms much smaller than that.  However, the mushrooms routinely reach sizes of a foot across or larger.  Many could easily be mistaken for abandoned soccer balls from far away.

#154: Panellus stipticus 1

Fungus Fact

#154: Panellus stipticus

This little brown mushroom isn’t much to look at… at least during the daytime. At night, however, the unassuming mushroom reveals its most interesting feature: it glows in the dark!  Known as the “Bitter Oyster,” “Luminescent Panellus,” or “Bitter Oysterling” (if you live in Europe), Panellus stipticus looks like a small, brown oyster mushroom.  A helpful feature that separates it from most other oyster-like mushrooms is that it has a tough texture.
