Crinipellis readiae G. Stev. 1964

[GS] Pileus 7-15 mm. diam., vinaceous russet, plane, thin, velvety fibrillose, somewhat striate. Gills adnexed, creamy to concolorous, thin, moderately crowded. Stipe 3-4 cm. x 1 mm., vinaceous russet covered with pale velvety pubescence. Spores 7-10 X 4um, non-amyloid, thin-walled. Cuticle of loosely woven, amyloid to pseudo-amyloid hyphae, with unbranched endings irregularly thickened, with clamp connections (Fig, 2/31, p. 37). HABITAT: in litter with basal mycelium binding dead leaves together, Puramahoi, 20.4.1955, Dorothy Read in Stevenson (type); & Kaingaroa, 12.3.1958, Stevenson. [EH] Spores comma-like, hyaline, neither amyloid nor dextrinoid smooth, 7.5-9 X 3.5-4 um.. Cheilocystidia numerous, fusoid, with prolonged neck or irregularly branched apically, hyaline, 25-40 X 5-10 um. Caulocystidia cylindrical, thin-walled, densely covering the upper part of the stipe. Cuticle a cutis of irregularly interwoven cylindrical hyphae, encrusted with brown pigment, clamp connections present. [Desjardin] The holotype specimen consists of about 2 very fragmented basidiomes in fair condition. As dried: Pileus striate, pruinose overall, reddish brown. Lamellae adnexed, subdistant with 2 series of lamellulae, broad, creamcoloured. Stipe 1 mm diam, pubescent, yellowish grey-brown. Basidiospores 8–9 × 3.8–4.5 μm [xm = 8.5 ± 0.3 × 4.1 ± 0.2 μm, Q = 1.8–2.3, Qm = 2.1 ± 0.2, n = 10 spores per 1 collection], ellipsoid, smooth, hyaline, inamyloid, thin-walled. Basidia clavate, 4-spored, clamped. Basidioles clavate. Pleurocystidia absent. Cheilocystidia scattered, lamellar edge fertile; 22–40 × 6.5–10 μm, irregularly clavate to lageniform or ventricose, mucronate or forked, projections obtuse, hyaline, inamyloid, thin-walled. Pileipellis a cutis of repent, subparallel, cylindrical hyphae 3–5 μm diam, non diverticulate, often with brown pigment incrustations. [JAC] cap hyphae clamped.Villose hyphae on stipe surface just an irregular tangle. No caulocystidia.Nothing to add to Desjardin. Mata's interpretation (and thus the first sequences of collections identified as this) are possibly correct. This material is the same as G. villosipes. G. readii sensu Mata (and GenBank) appears to be a misidentification of G. rimutaka.

Crinipellis readiae G. Stev. 1964

The holotype specimen consists of about 2 very fragmented basidiomes in fair condition. As dried: Pileus striate, pruinose overall, reddish brown. Lamellae adnexed, subdistant with 2 series of lamellulae, broad, cream-coloured. Stipe 1 mm diam, pubescent, yellowish grey-brown. Basidiospores 8–9 × 3.8–4.5 µm [xm = 8.5 ± 0.3 × 4.1 ± 0.2 μm, Q = 1.8–2.3, Qm = 2.1 ± 0.2, n = 10 spores per 1 collection], ellipsoid, smooth, hyaline, inamyloid, thin-walled. Basidia clavate, 4-spored, clamped. Basidioles clavate. Pleurocystidia absent. Cheilocystidia scattered, lamellar edge fertile; 22–40 × 6.5–10 µm, irregularly clavate to lageniform or ventricose, mucronate or forked, projections obtuse, hyaline, inamyloid, thin-walled. Pileipellis a cutis of repent, subparallel, diverticulate, often with brown pigment incrustations.
Notes: Horak (1971: 450) transferred the species into Collybia as C. stevensonii because the name Collybia readiae was already taken. However, Horak was unaware that there was already a Collybia stevensonii, so his nom. nov. created an illegitimate homonym. Correcting the gender ending to the feminine “stevensoniae” for Stevenson’s species versus “stevensonii” for the Berkeley & Broome taxon does not legitimize the illegitimate homonym. Status: This New Zealand species was transferred recently into Gymnopus. It does not represent a species of Crinipellis, but rather belongs in Gymnopus sect. Vestipedes.
