Description: Pileus -20 mm diam., hemispherical at first
becoming convex or umbonate-convex; light to dark brown, tobacco-brown; centre
with minute squarrose scales, fibrillose towards the dentate margin, dry, veil
remnants not conspicuous. Lamellae adnate, crowded (L 10-18, 13), ventricose;
beige or beige brown, edge paler, fimbriate. Stipe 15-25 x 2-2.5 mm, cylindrical,
without bulbous base; reddish brown, densely covered with white fibrils, not
pruinose; dry, solid, single or in clusters. Context brown beneath cuticle,
reddish brown in stipe. Odour none or slightly acidulous.
Spores 7.5-10 x 6-7 µm, nodose, knobs prominent
brown. Basidia 20-23 x 7-8 µm. 4-spored. Cheilo- and pleurocystidia 30-60 x
16-26 µm, fusoid, thick-walled, encrusted, hyaline to yellowish. Caulocystidia
cylindrical, thin-walled, 6-10 µm in diam., without crystals. Cuticle a trichoderm
of short-cylindrical hyphae (5-8 µm diam.), encrusted with brown pigment. Clamp
connections numerous.
Habitat: On soil under Leptospermum ericoides
(manuka). New Zealand.
Notes: In the field A. manukanea could be
confused with A. subclavata. Microscopical examination, however, will
show that the spores of A. manukanea are larger and bear much more pronounced
knobs, and cheilocystidia are metuloid with crystals.
