Resupinatus violaceogriseus G. Stev. 1964

[GS] Pileus up to 2.5 cm. diam., young specimens violet at margin, otherwise entirely violaceous grey, bell-shaped to broadly cup-shaped with inrolled margin, fibrillose at first, becoming pruinose with scattered fibrils; flesh greyish, tough gelatinous; sessile and pendulous attached at centre of upper surface. Gills radiating from point of attachment, moderately crowded, rather shallow and thick, violaceous grey. Spores 6-7 x 3 um, non-amyloid, hyaline (Fig. 1/46, p. 10). Hymenophoral trama of very loosely woven subregular hyphae with clamp connections. Cuticle of loosely woven branching hyphae, up to 5um, diam., with greyish walls 1um thick.HABITAT: on fallen Nothofagus menziesii, Nelson, 6.7.1949, A. Crawford in Stevenson (type). [EH] (as Marasmiellus) Spores elliptical to subcylindrical, hyaline, neither amyloid nor dextrinoid, smooth, 5-6.5 X 2.5-3 um Cheilocystidia broom-like. Cuticle of heavily diverticulate cells, clamp connections present. [JAC] spores length=5.3–7.2µm (µ=6.1, σ=0.59), width=2.3–3.5µm (µ=3.0, σ=0.29), Q=1.6–2.6µm (µ=2.05, σ=0.23), n=20. Nothing to add to Egon's account except that the gill face has regular crystal deposits and it isn't clear what source they have. There can be no doubt this is the same as recent collections.

Pileus up to 2-5 cm diam., young specimens violet at margin, otherwise entirely violaceous grey, bell-shaped to broadly cup-shaped with inrolled margin, fibrillose at first, becoming pruinose with scattered fibrils; flesh greyish, tough gelatinous; sessile and pendulous attached at centre of upper surface. Gills radiating from point of attachment, moderately crowded, rather shallow and thick, violaceous grey. Spores 6-7 x 3 µm, non-amyloid, hyaline (Fig. 1/46) P. 10). Hymenophoral trama of very loosely woven subregular hyphae with clamp connections. Cuticle of loosely woven branching hyphae, up to 5 µm diam., with greyish walls 1 µm thick. Spores smoot.
On fallen Nothofagus menziesii, Nelson, 6.7.1949, A. Crawford in Stevenson (type).
Pileus usque 2-5 cm diam., juventute margine violaceus, ceterum omnino violaceo-griseus, campanulatus usque late cupuliformis, margine involuto, primum fibrillosus, deinde fibrillis sparsis pruinosus; caro subgrisea, tenaciter gelatinosa; sessilis, pendulus, facie superiore medifixus. Lamellae ex origine adnectente radiantes, modice confertae, haud altae, crassiusculae, violaceo-griseae. Sporae 6-7 x 3 µm, haud amyloideae, hyalinae. Trama hymenophoralis ex hyphis subregularibus laxissime intertextis (cum fibulis) sistens. Cuticula ex hyphis ramosis laxe intertextis usque 5 µm diam. sistens, parietibus subgriseis in crassis.
Typus: A. Crawford. in Stevenson 719.
