Mycena fuscovinacea G. Stev. 1964

Description

[GS] Pileus 2.5-5 cm. diam., deep vinaceous brown, somewhat blotchy, more or less plane becoming somewhat waved at margin, moist, smooth; flesh buff, thin. Gills free or adnexed, pale vinaceous with creamy margins, deep, distant, rather thick, many with ribs between. Stipe 5-8 cm. x 3-8 mm., pale vinaceous, larger stipites twisted and striate, hollow, fragile, smooth, with creamy weft of hyphae at base. Spores 8-9 x 5-6um, amyloid, thin-walled; print white. Hymenophoral trama and tissue of pileus strongly pseudo-amyloid. Cheilocystidia 20-40 x 8 - 10 um , abundant (Fig. 2 151, p. 37). Smell faint, earthy. Drying dark purplish colour. HABITATin litter round standing podocarp stump, Waikanae, 15.5.1949, Stevenson (type); & in litter under exotic trees, Cawthron grounds, Nelson, 14.6.I 956, Dorothy Read. [JAC] Another Stevenson specimen that has undergone excessive heating and has then broken into tiny fragments. Lamellae with strong basal interveining. No cap or stipe ornamentation. Lamellar edge forming an entangle mass of thin hyphae in parts, perhaps originally partially gelatinised, with occasional bundles of cylindrical cheilocystidia. No cystidia looking anything like Stevenson's drawing The gill edge is noticeably less pseudoamyloid than the lamella trama. 4 spored. length=6.2–8.3µm (µ=7.2, σ=0.52), width=3.8–4.8µm (µ=4.3, σ=0.26), Q=1.5–2.0µm (µ=1.70, σ=0.13), n=24. As I suspected, this is the same my M. whakapapa, and the cheilocystidia are not as originally described.
