[GS] Mycena - small yellowish [text on card insert]. Pileus 2-10 mm. diam., ochraceous, hemispherical, sulcate striate at margins, velvety. Gills sinuately adnexed, greyish, moderately distant, long and short intercalated. Stipe 2-5 cm. x 0-5-1 mm., pale ochraceous above, light brown below, smooth with sparse hyphal fibrils at base. Spores 9-10 x 5 um, slightly thickened walls, with clear outer layer and amyloid inner layer either granular inner wall or granular contents. Hymenophoral trama ans tissue of pileus strongly pseudo-amyloid with some large cells, up to 50 x 30um. Cheilocystidia ornamented (Fig. 2/39, p. 37). HABITAT: singly in litter, Queen's Gardens, Nelson, 6.5.1957, Stevenson (type). [EH] Spores oval to elliptical, hyaline, weakly amyloid, smooth, 8.5-10.5 x 5-6um. Cheilocystidia numerous, fusoid, irregularly branched or broom-like, hyaline, thin-walled, 25-50 x 5—10um. Possibly introduced. [JAC] irregular fingers on apex of basidiolar-like cheilocystidia, or extensions from partially gelatinised ropes. Nothing like Stevenson's cystidia seen. EH figures closer, but not really like the material. Stem with small extensions and pseudoamyloid. Cap with fine surface diverticulae. 4 & 2 spored. Gill edge concolorous. The micro features are consistent with NZ material of M. olivaceomarginata. The edge colour fades in dried material. spores length=8.2–10.2µm (µ=9.2, σ=0.60), width=4.5–6.0µm (µ=5.3, σ=0.38), Q=1.6–1.9µm (µ=1.74, σ=0.09), n=20
