Cystodermella
Cystodermella Harmaja 2002, in Harmaja, Karstenia 42(2): 39 (2002).
Diagnosis: Agaricales; habitus of basidiocarp as in Cystoderma. Universal veil present. Pileus convex or plane; surface finely to coarsely granulose. Stipe covered with veil remnants except at apex; ring mostly lacking, sometimes present. Lamellae narrowly to broadly adnate. Flesh of stipe and pileus of continuous elasticity. Conidia (arthrospores) absent from context of pileus. Odour indistinct. Taste mild. Spores white in deposit, binucleate (Saar & Kullman 2000: three species examined, the type included), ellipsoid; wall without germpore, smooth, inamyloid, cyanophilic (at least in type species: Singer 1972). Cystidia of lamellae mostly absent; when present they are 'harpoon like' due to encrusted crystals. Cortex of pileus and stipe (apex excluded) formed by dry velar layer essentially composed of sphaerocysts. Hymenophoral trama of more or less parallel hyphae. Clamp connections present in hyphae of fruit body. Dried pileus, stipe, lamellae, flesh and basal mycelium of the type species do not exhibit fluorescence but retain their colours under ultraviolet light (with wave-lengths 254 nm and 366 nm; no difference to C. amianthinum; these are apparently the first observations on the responses of Cystoderma s. lato fruitbodies to ultraviolet light). Saprophytes of non-ligneous, rarely ligneous, plant litter; sometimes among mosses at the same time but probably not truly muscicolous.
