Onygena is a genus of fungus from the class Eurotiomycetes .
description
Onygena species live as saprophytes on horns, hooves, feathers and animal hair. The fruiting bodies , which are divided into stems and heads, are cleistothecia , i.e. the spores formed within the fruiting body are not released through defined openings, but by destroying the fruiting body. The spherical asci also have no active release mechanism, but are dusted together with the spores and then dissolve (prototunic asci). The Asci are in the Hyphengewebe embedded in the head of the fruit body, comparable to the scalp in the Gasterothecien the belly mushrooms . The hyphae are septate .
