In New Zealand there is no other species of Astrosporina (or Inocybe) which when fresh smells like bitter almonds. In the Northern Hemisphere at least two species of Inocybe, I. hirtella Bres. and I. scabella Fr. s.str. Kuhn, do have this same particular odour.

Lamellae adnate, ventricose; whitish turning beige-grey, with white fimbriate edge, L 14-20, 1 3 (-5). Stipe 15-25 x 2-3 mm, cylindrical, with small, marginate bulb at the base (-5 mm diam.); whitish, with brownish hue when old; whole length covered with whitish minute longitudinally arranged fibrils, conspicuous veil remnants absent; dry, hollow, single in groups. Context white. Odour strong, like bitter almonds (as I. hirtella Bres.).
Spores 8.5-10 x 5.5-6.5 µm, nodulose, brown. Basidia 22-30 x 8-10 µm, 4-spored. Cheilo- and pleurocystidia 40-60 x 14-20 µm, fusoid, thick-walled, hyaline, encrusted. Caulocystidia not distinctive. Cuticle a trichoderm of cylindrical hyphae (5-10 µm diam.), membranes encrusted with brown pigment. Clamp connections numerous.
