  • Heterodictyon Rostaf. (1873)

Features

The fruiting bodies are usually pedunculated sporangia, a calyculus may be present or absent. The delicate peridium is reduced to a structure of vertical, thickened threads that are interconnected by extremely fine, translucent transverse threads.[3] In some cases, however, the peridium may also appear like a net, as in Cribraria - species. Mostly dark, clearly visible dictydine granules are found especially close to the ribs of the peridia, the calyculus and the spores.[4]

Distribution

The genus is distributed worldwide, about two-thirds of the species are, however, [neotropic] ch. Many of their species are common in the respective distribution areas.[4]

Systematics and Research History

The genus was first described in 1794 by Christiaan Hendrik Persoon, type species is Cribraria rufescens .[4]

The genus includes at least 30 species, including:[3]
