Mycostilla Spirin & V. Malysheva View in CoL View at ENA , Antonie van Leeuwenhoek 112: 760, 2018, emend.
Description.
Basidiocarps appearing as small gelatinous outgrowths on a hardly visible joint subiculum, later fusing into reticulate or continuous compound fructifications. Hyphal structure monomitic, hyphae clamped. Tramal cystidia tubular, slightly tapering upwards, apically blunt, or absent. Gloeocystidia (if present) running more or less parallel to tramal cystidia. Basidia two – four-celled, pedunculate, with slender, distantly located sterigmata. Basidiospores thin-walled, subglobose, repetitive, often with one large oil drop.
Type species.
Dacrymyces vermiformis Berk. & Broome.
The generic description of Mycostilla is amended here to encompass a new species, M. chromatica . In contrast to the generic type, M. vermiformis , it has continuous (not reticulate) basidiocarps and lacks cystidia. Nevertheless, it is phylogenetically quite close to M. vermiformis and is therefore described as a Mycostilla . Basidia of both species are of the same shape (slightly larger in M. chromatica than in M. vermiformis ), and basidiospores are nearly identical.
