Abstract

The monotypic genus Pyropyxis is described based upon the type species, Peziza rubra Peck. Pyropyxis is distinguished by deeply cupulate, sessile, pink to reddish-orange apothecia. The ectal excipulum is composed of thick-walled cells forming a textura angularis tissue with the outer layer of cells occasionally giving rise to hyaline, moniliform hairs. The hymenium contains two types of paraphyses; most are hyaline, but some are filled with orange, crystalline pigments. The ascospores are eguttulate when fully mature but contain two small polar guttules when immature. A Dichobotrys anamorph is produced in axenic culture.
