Stagnicola

Stagnicola Redhead & A.H. Sm., Canadian Journal of Botany 64(3): 645 (1986)

Development gymnocarpic. Habit mycenoid/collybioid to phaeocollybia-like. Pileus conical to convex, umbonate, hygrophanous, smooth, lubricous-viscid to greasy, striate, tawny, fulvous to sienna, orange yellowish at margin. Lamellae adnexed-ventricose, crowded with olivaceous tints and concolorous edge. Stipe central, smooth, bay or purplish reddish, dark brown to blackish towards the base, horny, cartilaginous, shiny, often deeply tapering towards base, marasmius cohaerens-like, xeromphalina-like (but without forming a true pseudorhiza), with a saffron to ochre basal mycelial tomentum. Smell and taste indistinct or astringent, bitterish. Spore print deep olive buff to pale hazel brown. Spores ellipsoid to amygdaliform-reniform, smooth, without a germ-pore, pale hazel, yellowish brown in water (practically hyaline) under the microscope, non-dextrinoid, inamyloid, cyanophilous, non-metachromatic, binucleate. Basidia usually 4-spored, rarely 12-spored. Cheilocystidia thin-walled, cylindrical to fusiform. Pleurocystidia absent. Hymenophoral trama regular, consisting of parallel hyphae. Pileipellis a thin ixocutis of encrusted hyphae with yellow brown parietal pigment. Caulocystidia present. Clamp-connections present. Tissues non-sarcodimitic.
