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)
Brown, Olive, Orange or Tan Spored Suborder
Gills not free
Spore print tan, orange, deep ochre, yellowish olive, olive brown, rusty or cinnamon brown or deep brown
Ring usually either absent or not membranous
Terrestrial Brown Spored Family
Growing on the ground
Cap with prominent radial fibers, often splitting radially
All parts of the mushroom often scaly, scurfy, or tufted with minute hairs (barely visible on the stem in this image)
Cap usually less than 2" across
Dark Brown Scurfy Inocybe Section
Cap and stem covered with chunky scales and tufts of hyphae; typically dark brown
Inocybe calospora Quélet
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 1" across; umbonate
Stalk with a small whitish basal bulb
With deciduous trees
- Spores 9.5-13.5 x 8.5-11 µm, with very long spines (not as in the picture, where the spores are lumpy)
Pleurocystidia uncommon, ventricose but only slightly encrusted with crystals at the top, medium-walled, 35-55 x 10-20 µm
