Astrosporina viscata E. Horak 1978 [1977]
New Zealand: "Westcoast, Lake Hochstetter, 17.111.1968, leg. Horak". (PDD, 27109: holotype; ZT, 68/177: isotype)". "Fjordland N. P., track to Mt Luxmore; 9.1V. 1969, leg. Horak" (ZT, 69/331).
Pileus -35 mm diam., hemispherical when young, soon campanulate or convex with broad umbo, also becoming expanded with depressed centre; yellowish brown, beige or avellanous; innately fibrillose, viscid, veil remnants absent. Lamellae adnexed to sub free, crowded; whitish when young becoming chocolate or tobacco-brown, dark brown in aged carpophores, edge white, fimbriate. Stipe 20-75 x 3-6 mm, cylindrical, base rarely slightly swollen; whitish turning brownish or even dark brown when old, whole length pruinose; solid, dry, cortina absent, single in groups. Context whitish yellowish, reddish brown in upper parts of the stipe. Odour none.
Spores 7-9 x 5-6 µm, ovate with wart-like knobs, brown. Basidia 20-70 x 5-8 µm, 4-spored. Cheilo- and pleurocystidia 30-80 x 10-24 µm, clavate, cylindrical-fusoid, thick-walled, with yellow plasmatic pigment (in KOH), apex encrusted. Caulocystidia numerous, like pleurocystidia. Cuticle a cutis of cylindrical hyphae (3-10 ^m diam.), membranes gelatinised, encrusted with brown pigment. Clamp connections present.

Pileo -35 mm lato, e campanulato umbonato expanse, argillaceo vel avellaneo, viscido, fibrilloso. Lamellis adnexis, ex albido umbrino. Stipite -75 x -6 mm, cylindrico, albido, brunnescente, pruinoso. Odore nullo. Sporis 7-9 x 5-6 µm, gibbosis. Cystidiis
fusoideo-lageniformibus, crasse tunicatis, incrustatis. Caulocystidiis praesentibus, Habitatio ad terram in silvis nothofagineis. Nova Zeiandia. Typus (PDD, 27109).

The viscid pileus, the cylindrical pruinose stipe, and the small gibbous spores characterise this species. Macroscopically it could be taken as A. subclavata, but the shape of the cheilo- and caulocystidia distinctly separate the two taxa.
