Notes on Taxonomy: [Edit]

These two species are often hard to separate because of the confusing range for the macrocharacters which overlap. C. perennis seems to be the more cinnamon of the two, but not always! The width of the spores is a good microcharacter.

Coltricia cinnamomea
Cap 1-5 cm, vivid reddish brown (rusty aging amber) to dark brown aging wood brown; Zoned but somewhat blurred by radially fibrillose matted fibers, edges of zones often diffuse; Center flat to depressed, margin paper thin and hairy (ragged looking).
Pores reddish brown aging tan, not decurrent on stalk.
Spores 6.5-7.5 × 4.5-6.5 um (Hansen & Knudsen, 1997)
