Summary: features include small size, conic to bell-shaped viscid cap that is tawny in center and pallid over marginal area, but covered with dark russet fine scales, cap skin tough and separable, crowded pallid gills that become dull cinnamon with pallid edges, stem pallid at top but lower part covered with concentric zones of dark russet veil material, growth on burned ground, and microscopic characters; description derived from Smith(3) except where noted; type from ID, and reported from BC (Redhead(5) p.7), collections by Paul Kroeger at University of British Columbia, CHEMICAL REACTIONS with FeSO4 flesh quickly green
Cap: 1-2cm across, conic expanding to broadly conic or conic - bell-shaped; tawny in center and pallid over marginal area; viscid cap skin is tough and separable, surface covered with superficial, dark russet squamules [fine scales] representing the remains of the universal veil, slowly becoming bald
Flesh: pliant; pallid
Gills: broadly adnate, crowded; pallid becoming dull cinnamon, edges pallid and even
Stem: 1-2cm x 0.3-0.4cm, narrowing downward, solid; ground color "pallid but so densely covered by concentric zones of dark russet veil material as to almost obscure the ground color" except at top
Veil: russet-colored universal veil leaves fine scales on cap and dense concentric zones on stem except at top
Odor: not distinctive
Taste: not distinctive
Microscopic spores: spores 6-7.5 x 4-4.5 microns, ovate to elliptic in face view, elliptic to obscurely inequilateral in side view, minute apical germ pore, cinnamon brown in KOH, paler and brighter rusty brown in Melzer's reagent, wall about 0.25 microns thick, [presumably smooth]; basidia 4-spored, 18-24 x 5-7 microns, clavate, colorless to pale yellow in KOH; pleurocystidia abundant, 33-46 x 9-16 microns, 'fusoid-ventricose to utriform (apex rounded in some), thin-walled, yellowish in KOH, content "colloidal" but merely yellowish in Melzer's reagent', colorless when fresh, smooth, cheilocystidia similar to pleurocystidia; caulocystidia scattered near stem apex, similar to pleurocystidia or larger; clamp connections present
Spore deposit: [presumably brownish]
Habitat / Range
type on burned (partially) chip dirt, (Smith), in groups in burned areas in fall (Scates)
according to Scates(1) and Smith(3), there are six others that favor burned areas: P. brunnescens (yellow veil, thicker stem), P. carbonaria (ferruginous red veil, cap lighter in cap), P. highlandensis (whitish to buff veil), P. molesta (white veil that becomes dingy brownish orange and separates into zones and patches on stem, pale pinkish-buff young cap that develops a reddish or brownish flush), Pachylepyrium carbonicola (pallid veil, spore walls 0.5-1.8 microns), and Pholiota subsaponacea (dull cinnamon veil, unpleasant taste)
