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.Michael J. Dykstra, Harold W. Keller: Mycetozoa In: Illustrated Guide to the Protozoa, John J. Lee, Gordon F. Leedale, Phyllis Bradbury, Society of Protozoologists, 2nd edition, volume 2, pp. 952-981 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.Marie L. Farr: Myxomycetes, New York Botanical Garden, 1976, pp. 88-89
