Crinipellis filiformis G. Stev. 1964

K(M) 122113, Stevenson 213. Dennis Desjardin's comments on this collection "The holotype specimen consists of one packet containing a leaf fragment with a few reddish brown, glabrous, wiry rhizomorphs; and a second packet containing one broken stipe plus one quarter of one pileus. As dried: Pileus 2 mm diam, disc with a small brown papilla, shaggy-hairy, cream-colored on the margin. Lamellae close, narrow, cream-colored. Stipe 8 × 0.5 mm, greyish brown, with cream-colored pubescence.Basidiospores 8.3–10.5 × 4.2–5.2 μm, xm 9.1 +- 0.7 x 4.7 +- 0.3um, Q = 1.7-2.2, Qm = 1.9 ; n = 12 spores per 1 collection, ellipsoid, smooth, hyaline, inamyloid, thinwalled. Hymenial elements not observable: no basidia, basidioles or cystidia seen. Pileipellis of tangled to subparallel and agglutinated, thick-walled hairs. Hairs > 300 x 2.2-3.5(-5.5)um, cylindrical to sinuous, gradually narrowed to an acute or subacute tip, hyaline, inamyloid or dextrinoid; walls smooth, 0.5-1.3 um thick; no secondary septa seen near the tips. Habitat: Fallen leaves. Known distribution: New Zealand. Notes: Data on hymenial cells were not obtainable because of the poor quality of the limited material in the holotype specimen. Features of the cheilocystidia are required for accurate taxonomic placement. Status: Crinipellis filiformis will remain an insufficiently known species of Crinipellis until more material becomes available for analysis." [JAC] This is a mixed collection with one packet containing a 'Rhizomarasmius' (no caps remaining) and the other with the small fragment of a Crinipellis. The Crinipellis is not associated with a leaf. It is unclear if Stevenson's description was based on the mixture, although it seems probable given the epithet, which does not apply to the Crinipellis in the packet. Cheilocystidia found and with short setula. Spores length=8.3–10.2µm (µ=9.3, σ=0.50), width=3.9–4.9µm (µ=4.4, σ=0.33), Q=1.8–2.4µm (µ=2.11, σ=0.16), n=20. The spores are slightly larger than Stevenson and Desjardin suggest. This material is consistent with C. substipitaria as a synonym. It is distingusihed from C. scabella by spore Q (=1.7), association with poaceae (noting fact that substrate of type of C. filiformis is debateable) and presence of cheilocystidia with setae (differing from all Euro species in that regard).
[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).
