[GS] Pilew 5-9 mm. diam., fuscous, paler at margin, hemispherical becoming plane with a sharp umbo, covered with brown fibrillose scales. Gills free, creamy white, rather crowded. Stipe 1-3 cm. x 0.5 mm., brown, fibrillose, tough. Spores 8-9 x 6-7um, non-amyloid, thin-walled. Hymenophoral trama non-amyloid. Cheilocystidia and pleurocystidia fairly numerous, 25-30 x 51um, with branched tips. Cuticle with long unbranched hyphae, amyloid to pseudo-amyloid, 5um diam., with walls 2um thick (Fig. 2/29, p. 37). HABITAT: on fallen dead leaves, Lake Papaitonga, Levin, 27.10.I 947, Stevenson (type). [Desjardin] The holotype specimen consists of 5 intact or fragmented basidiomes in fair condition, one attached to a leaf. As dried: Pileus 3–4 mm diam., conical, radially fibrillose, pale brown. Lamellae subdistant to close, broad, cream-colored. Stipe 10–25 × 0.5 mm, shaggy, ochraceous; rhizomorphs absent. One Mycena basidiome is also in the collection. Basidiospores 8.6–10.5 × 6.4–7.4 (–7.7) μm, [xm = 9.5 ± 0.7 × 7.0 ± 0.4 μm, Q = 1.2– 1.5, Qm = 1.4 ± 0.1; n = 10 spores per 1 collection], broadly ovoid, smooth, hyaline, inamyloid, thin- to firm-walled. Basidia clavate, clamped. Basidioles broadly fusoid. Pleurocystidia absent. Cheilocystidia common, lamellar edge heteromorphous; main body 14– 23 × 4.5–6.5 μm, subcylindrical to clavate with numerous apical appendages; apical appendages 1.5–4 × 1.2–1.5 μm, rod-like, obtuse, seldom forked, hyaline, inamyloid, thin-walled. Pileipellis of tangled to subparallel, thick-walled hairs. Hairs > 300 × 3.8–5 μm, cylindrical to sinuous, narrowed near the apex to an obtuse tip, hyaline to yellowish brown, inamyloid to strongly dextrinoid; walls smooth, 0.5–2.5 μm thick. Stipitipellis with hairs like the pileipellis. Habitat: On fallen dead leaves. Known distribution: New Zealand. Notes: This represents a good species of Crinipellis, distinctive because of the very broad ovoid spores and the clavate-setulose cheilocystidia. [JAC] The packet says under Beilschmedia, which seems to be a common substrate for NZ Crinipellis. Cheilocystidia 23 x 10. Spores (including apiculus) length=7.4–9.2µm (µ=8.2, σ=0.51), width=3.1–4.1µm (µ=3.8, σ=0.26), Q=1.8–2.5µm (µ=2.18, σ=0.17), n=16. The material is immature and there are numerous spores amongst the lamella. Some are lightly pigmented and verrucose and belong to a hypho or slime mould. Some are smooth, hyaline and variable in size and probably belong to a heterobasidiomycete? Stevenson, Desjardin & myself may have measure different spores. The spores I measured are few but are in accord with the material of C. filiformis. This specimen, and that of original and recent material of C. filiformis, may represent the range of a single taxon, or if the spores are different, then this is a good independent taxon.
