Specimen notes
Public Note:
fruitbody gelatinised. Gill edge not separable. Cap felty, gill face grey, with white edge from cheilocystidia. Cap edge with villose thick walled glassy hairs, not dextrinoid, slightly enlarged at apex and coralloid with crystals, hairs emerging from layer of brown hyphae similarly ornamented. Spores hyaline, inamyloid (maybe very slightly amyloid), cylindrical, slightly constricted waist, 7 x 3um. Gill edge sterile with layer of coralloid cells ornamented like hairs. Cystidia descending a little across gill face but concentrated near edge. In plan view look like craters because of broad central filament and ornamentation around edge. Cystidia not really metuloids. Horak to Hohenbuehelia. Looks more like Resupinatus to me but that with subglobose spores and no cheilocystidia (in Horak's narrow sense but not that of NM2). Largent to Resupinatus. Presumably Horak transferred this to Marasmiellus because of a narrower concept of Resupinatus based on R. applicatus with globose spores and no cheilocystidia (see the Beitrage). Corner (Nova Hed 111) questions Resupinatus/marasmiellus in his description of R. subvinaceus - which looks identical to R (Marasmiellus) violaceogriseus and maybe a later synonym? This taxon is clearly very close to Resupinatus alboniger and its reasonable that Singer erected Asterotus for this and dealbata, except sequences show it is a Resupinatus. The only difference seems to be that R.a. has ramealis cap hyphae that are brown and not thick walled, and this has a more violaceous colour. Whatever, this taxon needs transferring to Resupinatus. R. argentinus is a synonym of R. alboniger, R. chilensis has much broader spores. Material to Greg Thorn.
