K(M)235193. Stevenson 1141 on falllen cones of Picea, Cawthron, Nelson, 20/5/2956. Regarding M. conicola it is useful to refer to the comments of Grgurinovich in the Mycenas of SE Australia; "Stevenson (1964) described M. conicola G. Stev. from New Zealand. Horak (1971) recorded that this species approaches M. flos-niveum Kuhner, a species belonging in Section Mycena. Mycena flos-niveum has clavate cheilocystidia that are 'covered with fairly few, unevenly spaced, usually rather coarse, simple to branched, straight to curved excrescences' (Maas Geesteranus 198.5a, 1992b). Horak's drawings (1971: Fig. 4 (68)) show M. conicola with clavate to sphaeropedunculate cheilocystidia covered with abundant evenly spaced short cylindrical excrescences. Mycena conicola clearly belongs in Section Filipedes and not Section Mycena. Like M. austrofilopes, M. conicola has two-spored basidia. The former species can be distinguished by its moderately close to close lamellae, its stipe that has strigose hairs towards the base rather than 'spreading hyphal hairs' (Stevenson 1964), its larger basidiospores (7.3- 13.5 x 4.3-7.1 um for var. austrofilopes, compared with 10-12 X 4—5 um for M. conicola (Stevenson 1964)), the absence of pleurocystidia, and its habitat on litter under species of Eucalyptus rather than on fallen cones of spruce.". As a consequence, and given that both M. austrofilopes and M. filopes occur in New Zealand in both native and exotic habitats, the issue is reduced to ascertaining which of these species M. conicola is. In this material there are no pleurocystidia and the cheilocystidia measure to 30 x 15um and spores length=9.0–11.8µm (µ=10.0, σ=0.69), width=3.8–5.4µm (µ=4.7, σ=0.40), Q=1.7–2.5µm (µ=2.16, σ=0.19), n=22. Number of sterigma not seen due to degradation. A mount does show some conspicuoulsy larger spores so 2 & 4 spored. Smaller (abundant) spore size length=9.0–10.9µm (µ=9.9, σ=0.51), width=3.8–5.3µm (µ=4.6, σ=0.38), Q=1.7–2.5µm (µ=2.15, σ=0.19), n=20. The evidence suggests this is M. austrofilopes rather than M. filopes. None of the characters quoted by Grgurinovich for separation are adequate.
