Lepiota adusta (E. Horak) E. Horak 1980
Material. - New Zealand: South Island: Nelson, Whanganui Inlet, Mangarakau, 16. V. 1968, HORAK (PDD, 27140, holotype).
Habitat. - On soil among litter in coastal, mixed forests. - New Zealand.
Remarks. - As pointed out in the key L. adusta comes macroscopically close to two other Australasian species of Lepiota, viz. L. atrata HORAK (New Caledonia) and L. exocarpi CLEL. (Australia). These three species are, however, well separated by their specific microscopic characters (shape-size of spores and cheilocystidia).
New Zealand: South Island, Nelson, Whanganui Inlet, Mangarakau, 16. V. 1968, leg. Horak (PDD 27140, holotype, ZT 68/454, isotype).
This species is closely related to L. pseudofelina Lange sensu Kuhner (1936) et Locquin (1945) from which it differs by the general aspect of the carpophores, the colour of the lamellae, and the shape of. I the cheilocystidia.
Pileus 10-20 mm diam., conico-convex becoming umbonate or obtusely campanulate, centre black or fuliginous, breaking up into concolorous, concentric velutinous or tomentose bands and squamules on a paler background, dry, veil remnants absent, margin estriate. Lamellae free, ventricose, crowded, whitish when young turning to pale argillaceous, edge albofirmbriate. Stipe 20-40 x 3-5 mm, cylindric or attenuated towards apex, pale brown, covered by small, irregularly shaped, black squamules and short rings from veil towards base, cortina absent, fibrillose, dry, solid, single in groups. Context dark brown beneath cuticle. Odour sourish. Chemical reactions on pileus:KOH - negative. Spores 7-8.5 x 2.5-3.5 µm, spurred, hyaline, dextrinoid, smooth, germ pore absent. Basidia 1&-22 x 6-7 µm, 4-spored. Cheilocystidia 15-25 x 7-12 µm, clavate or vesiculose, thin-walled, hyaline, forming sterile seam on gill edge. Pleurocystidia absent. Cuticle a palisade of erect cylindric or subfusoid cells (80-200 µm x 6-12 µm), with brownish pigment in membrane or encrusting pigment. Clamp connections numerous.
On soil in forests (under Dacrydium, Metrosideros, Dracophyllum). New Zealand.
Pileus -20 mm, umbonato-convexus vel campanulatus, nigro-brunneus, velutinus. Lamellae liberae, albae. Stipes -40 x -5 mm. cylindricus vel subclavatus, pallide brunneus, squamis nigris e velo dense obtectus. Sporae 7-8.5 x 2.5-3.5 µm, calcaratae. Ad humum in silvis. Novazelandia
Typus PDD 27140
