LentinoLignoTrich     Subtribe

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)

Spore print "light-colored": white or buff, sometimes tinged with pink or tan. Greenish and (except for the Russulales) yellow spore prints also go here
Stalk fibrous, not fracturing like a piece of chalk

None of the special features distinguishing the other white-spored genera:
Gills not free, as in the Lepiotas and Amanitas
Basidia not extra-long, as in the Hygrophoraceae
Spores smooth, except for Lentinellus

Lignicolous Trich     Subfamily Growing on trees or dead wood, leaves, or sticks, or organic debris, often in moss

Links from Look-alikes Tough LignoTrich     Tribe Assume a lateral stem, unless otherwise noted in the diagnoses below If laterally stemmed, then gills strongly decurrent

Diagnosis

• All mushrooms with serrated gills go here
  
• If the stem is central and well-developed, then the fruiting body (even the cap) is large and extremely tough

• Cap often scaly or furry, with scales or fur a different color than the cap surface
  
• Fruiting body tough to extremely tough, especially if large

Narrow down your identification:

• Fruiting body flexible, sessile or with a very short stipe
  
• Cap up to four inches across, often furry
  
• Spores spiny; amyloid or with amyloid spines; nearly round

• Cap usually scaly, often quite large
  
• Fruiting body tough to extremely tough
  
• Stalk central, well-developed
  
• Spores inamyloid, smooth, elliptical

Lookalikes: Megacollybia platyphylla Gills often irregularly eroded in age, but not really serrated. Cap often virgate, but not truly scaly.
