[GS] Pileus 1-2 cm. diam., ochraceous buff, plane to concave with a downrolled margin, matt; flesh ochraceous buff. Gills decurrent, ochraceous buff, thick, shallow, moderately distant, forking. Stipe 1-1 -5 cm. x 1-2 mm., ochraceous buff, pruinose, solid, fleshy. Spores 10-11 x 4-5um strongly amyloid, moderately thin-walled (Fig. 1/38, p. 10). Hymenophoral trama subregular, hyphae up to 5um diam.; basidia 20-25 X 5-8um. Cuticle of almost parallel hyphae up to 5um diam. with clamp connections. HABITAT: amongst tussock grasses, Waipori, 31.5.1953, Stevenson (type). [EH] Spores subfusoid, amyloid, hyaline, smooth, 9.5-12 X 3.5-4.5 um. Cystidia none. Cuticle a cutis consisting of regularly arranged, cylindrical, repent, clamp-bearing hyphae, encrusted with brownish pigment. [JAC] stem base would indicate this was on soil (in indigenous grassland) and not decaying culms or wood. The spores are very amyloid, and smooth, thin-walled and collapsing, like some Mycena, but without dextrinoid gill trama. Gills are in series of 2 and do fork. Cantharelulla is a reasonable placement until more collections found, but possibly Pseudoomphalina. Lodge et al exluded C. waiporiensis from Cantharellula 'on basis of morphology' but without explanation. Certainly not something I have seen in NZ. Gill tissue exuding oil drops into melzers. 4-spored.Cap and unclamped cutis, without pigment. Spores length=9.1–11.5µm (µ=10.2, σ=0.73), width=3.8–4.9µm (µ=4.2, σ=0.31), Q=2.0–2.8µm (µ=2.42, σ=0.20), n=22. Perhaps related to Mycena 'Kennedy's Bush' - Atheniellaceae
