Description: Pileus 20-30 mm diam.; hemispherical, convex
to campanulate or umbonate-expanded; beige-brown to hazel-brown; dry, silky
to fibrillose, rimose, later splitting towards estriate margin; veil remnants
absent. Lamellae adnexed to sub free, crowded, ventricose; argillaceous turning
deep brown, edge albo-fimbriate or concolorous. Stipe 30-40 x 3-4 mm, cylindrical
or slightly attenuated towards apex, at base with marginate bulb (-6 mm diam.);
concolorous with pileus or paler; dry, pruinose all over, striate, veil remnants
absent, solid, single. Context brownish. Odour and taste acrid.
Spores 10-13 x 8.5-10 µm, ovoid, with numerous
conical blunt projections, substellate, brown. Basidia 25-35 x 7-9 µm, 4-spored.
Cheilo- and pleurocystidia 40-50 x 13-17 µm, fusoid, hyaline, metuloid (-3 µm
diam. near apex), encrusted with crystals. Caulocystidia like cheilocystidia
but larger, 50-60 x 15-20 µm. Cuticle a cutis of fasciculate not gelatinised
hyphae (3-7 µm diam.), membranes encrusted with brownish (KOH) pigment. Clamp
connections present.
Habitat: On soil under Leptospermum ericoides.
New Zealand, Northern Hemisphere.
Notes: It may surprise one that this common Northern
Hemisphere species occurs in New Zealand. To my knowledge A. asterospora
is also found in New Guinea, the Solomon Islands, and Malaysia. Under these
circumstances the record in New Zealand is not as isolated as it first appears.
