Inocybe calospora

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)

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

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

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.

Diagnosis

• Cap up to 1" across; umbonate
  
• Stalk with a small whitish basal bulb
  
• With deciduous trees

Microscropic Characters

• 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
