Resupinatus tristis G. Stev. 1964

Description

K(M) 235135, Stevenson 1431. The type requires little further annotation. It is consistent with the current interpretation of this species. The gill edge is difficult to observe, being obscured by masses of agglutinate spores. There is some evidence for occasional cystidia similar to the pileipellis.

Resupinatus tristis G. Stev. 1964

Description

Pileus 1.5-3 µm diam., creamy-fawn with greenish tinges, orbicular to reniform, subfibrillose to velutinate; flesh thin; laterally attached. Gills creamy, moderately thick, distant and shallow with gill-like folds between. Spores 9 x 5-6 µm, non-amyloid, thin-walled (Fig. 44). Hymenophoral trama more or less regular, with some thick-walled hyphae. Cuticle of loosely woven hyphae, 2-3 µm diam., with clamp connections, mostly thin-walled, gelatinized.

Habitat

On standing dead Beilschmiedia, Levin, 15.11.1958) Stevenson (type).

Latin

Pileus 1.5-3 µm diam., cremeo-hinnuleus viridulo-tinctus, orbicularis usque reniformis, subfibrillosus usque velutinosus, lateraliter adnexus; caro tennis. Lamellae cremeae, modice crassae, distantes, haud altae, plicis lamelliformibus interspersis. Sporae 9 x 5.6 µm, haud amyloideae, parietibus tenuibus. Trama hymenophoralis plus minus regularis, hyphis nonnullis cum parietibus crassis. Cuticula ex hyphis laxe intertextis sistens, 2-3 µm diam., cum fibulis, parietibus plerumque tenuibus gelatinatis.

Notes

When collected this fungus was dry and papery but it is probably gelatinous when fresh.
