Cribraria Explained
Cribraria is a genus of slime molds from the group of Myxogastria. It comprises about 30 species, some of which are extremely difficult to distinguish.
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.[1] 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.[2]
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.
Systematics and research history
The genus was first described in 1794 by Christiaan Hendrik Persoon, type species is Cribraria rufescens .
