Pseudobaeospora deckeri C.F. Schwarz

Diagnosis fuente 
Pseudobaeospora species can be distinguished by caps with inrolled margins, moderately spaced gills, course hairs at the stipe bottom, and a pileipellis that is usually a cutis. There are three named species of Pseudobaeospora in California: P. deckeri is distinct by its lilac to purple colors, P. stevensii with a dark-brown to mahogany-brown cap, and P. aphana with a brownish cap with slight lilac sheen that is paler towards the.
Fruitbodies collybioid, entirely rubbery-tough to fleshy and slightlycartilaginous when fresh, brittle in age, but rather persistent. Pileus 10–27 mm wide, broadly convex and circular to plano-convex or uplifted and irregularly wavy; margin of young specimens distinctly but narrowly involute and in some specimens distinctly ribbed; very finely pruinose, evenly or in zones or blotches, especially near margin, in age nearly glabrous; deep royal purple (16E–F8) when young and moist, fading to dull brownish or grayish purple (14F4–6), sometimes in age with areas of obscure orange-brown tones (5D5), at margin paler to nearly white. Flesh thin, pallid lilac to darker purple just above lamellae. Lamellae L = 22–38(50), l = 3–5, subdistant to fairly close, adnate to finely and obscurely sinuate, ventricose in age, in some specimens intervenose and transvenose, when young dull gray (8B1–2) to dull lilac (13E3),in age distinctly ochre brownish (6C–D8); margin often thick, even to slightly irregular. Stipe (13–)29–50(–85) × 2–4.5 mm, equal or nearly so, at apex with belts or zones of fine, pale squamules, sometimes quite dense, with a fine pruina below these squamules over the upper quarter of the stipe, especially visible in young specimens, very dark purple (15F8) to royal purple (16D7–8) more or less remaining so at apex, but lower portions becoming duller purple to reddish-brown (11F7, 12D6, 12F4), at base usually conspicuously strigose, this tomentum white to lilac or purplish; base slightly rooting and bound to particles of substrate; flesh solid, dull, grayish purple, cartilaginous. Odor indistinct, although dried specimens wetted with alcohol emitted a ‘mushroomy’ odor (like Agaricus bisporus). Taste weakly but distinctly peppery or acrid.
