Description:AURISCALPIUM VULGARE S.F. Gray
Basidiomes solitary or proliferating and then several springing from common base. Pileus up to 20 mm across, supported subapically by a stipe from a notch on its side, more rarely seemingly with a central stipe, reniform, plano-convex or at the most shallowly depressed, not zoned, villose with a few scattered bristle-like hairs or densely hispid, glabrescent with old age, pale yellowish brown, pinkish brown, dark brown, finally blackened. Stipe 10-60 x 1-2 mm, straight or flexuous, equal or tapering above, hispid, dark brown, the base swollen 4-7 mm, and generally of a lighter brown. Spines 0.5-3 mm long, fairly distant, subulate, brownish fleshcolour, acquiring a whitish bloom from the ripe spores. Context of the pileus up to 0.5 mm thick, tough, not zoned, white, bounded by a black line at the upper surface and covered with tomentum and bristles.
Context of the pileus dimitic, consisting of generative and skeletal hyphae which have colourless walls in the white part of the context, dark walls in the black part and in the tomentum. Generative hyphae (of the white context) 1.8-2.2 µm wide, thin-walled (cell-walls less than 0.5 µm thick), branched, septate, occasionally anastomosing, with clamp-connections. Skeletals 2.2-3.6 µm wide, thick-walled to almost solid, undulating, often somewhat kinked and irregular through abortive side-branches. Context of the spines made up of generative hyphae, skeletals and oleiferous hyphae, the latter bending outwards in the distal part to form the gloeocystidia. Generative hyphae with clamps at all septa. Skeletals less irregular than in the context of the pileus. Basidia 18-24 x 6-6.5 µm, clavate, with basal clamp (inconspicuous with age), 4-spored. Spores 4.5-5.6 x 3.5-5 µm, broadly ellipsoid, adaxially flattened, minutely spinulose, colourless, amyloid, with oblique apiculus. Gloeocystidia numerous, projecting beyond the basidia, the distal part fusiformly swollen, up to 6 µm wide, thin-walled.
