Misspellings: Coltrichia perennis
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.
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)
Cap 2-13 cm, whitish tan, soft orangish brown, yellow brown (golden cinnamon) to dark brown aging grayish; Distinctly zoned with sharp edges; Radially fibrillose or appressed velutinate surface; Center flat to depressed, margin thin and rounded.
Pores grayish brown aging tan, normally decurrent on stalk.
Spores 6.5-9 × 3.5-5 um (Hansen & Knudsen, 1997)

Pileus coriaceous, circular, infundibuliform, 3-6 em. broad, 1.5-3 mm. thick; surface zonate, short-tomentose, substriate, ferruginous to cinereous, the zones sometimes glabrous and chestnut-colored; margin very thin, entire to lacerate, inflexed when dry; context very thin, concolorous, scarcely a mm. thick;tubes short, grayish-umbrinous within, 1-3 mm. long, mouths small, angular, 2-4 to a mm., whitish when young, becoming fulvous, edges thin, dentate to lacerate, soon collapsing; spores ovoid, smooth, pale-yellowish-brown,4-6 X 2-3.5 p; stipe bulb- ous and often united with that of neighboring plants at the base, tapering upward, velvety, ferruginous to fulvous, solid, corky, 3-5 em. long, 2-5 mm. thick.
Rather common throughout on exposed sandy or burnt soil in woods.
Habitat/range: On the ground in coniferous forests, typically on sandy soil along paths and lanes or in openings, ectomycorrhizae formed in pure culture synthesis with jack pine (Pinus banksiana) (Danielson 1984). In BC, known from Dawson Creek, Clearwater, and Revelstoke south to the BC/WA border. Elsewhere in western North America, known from AB and WA south to NM and AZ.Basidiomata stipitate, small to medium; stipe central, infrequently excentric, 2–7 cm long, 1–10 mm thick, solid, surface velvety, brown; pileus circular in outline, funnel-shaped or flat or slightly convex, 3–10 cm broad; pileus surface appressed-fibrillose, often silky and shining, sometimes dull, usually concentrically zonate, pale cinnamon to deep brown, some weather to grey; context 1–2 mm thick, not duplex, brown; tubes 1–3 mm deep, brown; pore surface yellow brown to brown or sometimes grey; pores 2–4 per millimetre, angular to round.
Hyphae 4–8 μm diameter with simple septa, walls thin to thick, hyaline to rusty brown, hyphae on pileus surface with distinctive dichotomously branched apices (appearing antler-like), walls thickened, yellowish brown, 3–8 μm diameter; basidiospores 6–10 × 3.5–5.5 μm, narrowly ellipsoid to el- lipsoid, walls pale yellowish brown, smooth, weakly dextrinoid.
Notes: Because of its colour and terrestrial, stipitate habit, C. perennis might be confused with Onnia tomentosa, but the latter has setae and much larger and thicker basidiomata.
