Species Information
Summary:
Features include a thin silky-shiny cinnamon to amber-brown cap that stains black with KOH, rusty brown flesh, a brown pore surface, and a reddish brown to dark brown stem.
Chemical Reactions:
cap surface stains black with KOH (Arora), flesh black with KOH (Lincoff)
Microscopic:
spores 6-10 x 4.5-7 microns, oblong to broadly elliptic, smooth, weakly dextrinoid, golden yellow, thin-walled to distinctly thick-walled, cyanophilous; basidia 2-spored to 4-spored, 18-30 x 5-7 microns, clavate; setae or cystidia or other sterile elements absent; hyphal system monomitic: generative hyphae 2-5 microns wide in hymenium, (in cap and stem up to 10 microns in diameter and there sometimes very thick-walled), with simple septa, first thin-walled and colorless, "later more thick-walled and golden to light rusty brown, septation frequent in hymenium and subhymenium, more scattered in the context where the hyphae are longer and straighter and not branched to the same degree as in the hymenium, branching at right or wide angles", (Gilbertson), 6-10 x 4.5-7 microns, elliptic, smooth, (Arora)
Spore Deposit:
yellowish-brown (Arora)

Habitat and Range
SIMILAR SPECIES
Coltricia perennis is typically in coniferous forests, the cap is generally 3-10cm across, the cap surface is dull, the flesh is 0.1-0.3cm thick, the stem is generally 1.0cm wide, the spores are 3.5-5.5 microns wide, and there are antler-like hyphal tips on the cap surface, whereas C. cinnamomea is generally in hardwood forests, the cap is rarely over 4cm across, the cap surface is shiny, the flesh is up to 0.1cm thick, the stem is up to 0.6cm wide, the spores are 4.5-7.0 microns wide, and antler-like hyphal tips on the cap surface are lacking, (Ginns(28)). C. perennis has larger fruitbodies, a more dull, yellowish brown to gray and often more hirsute cap, and narrower spores, (Gilbertson), C. perennis is up to 10cm, has strongly zoned velvety rather than silky surface, usually thicker stem and brown to grayish-brown pores that are sometimes decurrent, (Arora); Coltricia montagnei has maze-like pores or concentrically arranged plates, (Arora); Polyporus and other stemmed polypores in general do not have rusty brown flesh (Arora)Habitat
annual, on the ground usually in deciduous forests, apparently not a wood-rotter, (Gilbertson), "solitary or in small groups on ground or moss in woods, often along well-beaten paths, roadbanks, and in clearings (rarely on rotten wood)", (Arora)
