Mycena alexandri Singer

Originale versionem
Pileus 4-13 mm across, acutely conical in young stages, becoming broadly conical with age, sometimes with a small umbo or papilla, sulcate, translucent-striate or not striate, pruinose, glabrescent, fulvous, usually with a dark yellow-brown centre, somewhat paler at the margin, drying to yellowish brown; sometimes with a pink hue. Odour of iodoform when drying. Lamellae 13-16 reaching the stipe, ascending, narrowly adnate, not decurrent with a tooth, yellowish to pale fulvous, sometimes with a pink tinge. Stipe 25-65 x 0.5-1 mm, somewhat firm, hollow, terete, equal, straight to somewhat flexuous, pruinose, glabrescent, fulvous to brownish, often fairly dark, the base densely covered with long, coarse, flexuous, whitish fibrils.
Basidia 22-30 x 5.5-7.5 µm, slenderly clavate, 4-spored, with sterigmata up to 5 µm long. Spores 7.5-12 x 4.3-5.5 µm, pip-shaped to broadly pip-shaped, Q 1.6-2.5, Qav ~ 2.0, smooth, amyloid. Cheilocystidia 14-32 x 6-14 µm, forming a sterile band, clavate, covered with more or less evenly spaced warts and cylindrical, simple to branched excrescences 1-12 x 0.5-1 µm. Pleurocystidia absent. Lamellar trama dextrinoid. Hyphae of the pileipellis 1-5 µm wide, covered with warts and simple to branched, straight to curved cylindrical excrescences, tending to become somewhat gelatinized, and eventually forming dense masses. Hyphae of the cortical layer of the stipe 1.5-4 µm wide, not gelatinized, covered with warts or straight to somewhat curved cylindrical to conical excrescences 2-6 x 1 µm, terminal cells cylindrical to clavate, diverticulate. Clamp connections present in all tissues.
