Key to Gilled Mushrooms Key
This is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.
Fruiting body containing fibers (usually in the stalk)
Pink Spored Suborder
Spores pink or reddish
Often growing on wood
Big Volvariella Section
Cap typically more than 2" across
Here are the characters that distinguish this species from the others in its group. For its more general characters, see higher up on the page.
If there's just a few words or a microscopic feature here, a more thorough description can be found above.
- Cap up to 4" across; brownish grey; with blackish virgate streaks
Volva large; brownish, at least towards the top
On organic debris in greenhouses or other situations where it can be warm all year
This is the "straw mushroom", cultivated in tropical Asia and only common in tropical climates. But it can occur wherever it gets shelter somehow from the winter
My dad and I were fortunate enough to find tremendous fruitings several years in a row in New York, on a huge leaf-pile where a hospital dumped all their yard waste. Apparently the heat of decay kept the interior of the pile warm enough for this mushroom to thrive
