[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. Both Stevenson and Desjardin appear to have figured and measured these. The spores of the Crinipellis are few but are in accord with material of C. filiformis. This specimen, and that of original and recent material of C. filiformis, appear to represent the range of a single taxon, for which the name C. filiformis will stand, and this as a later synonym (p43 versus p42 of Stevenson).
