Diacheopsis is a genus of slime molds fromthe Stemonitidae family . The genus includes seventeen species and is common in the northern hemisphere.

features

The Plasmodium is gray or orange, but not known in most species. The fruiting bodies are more or less closely spaced, mostly sessile, rarely short-stalked sporocarp or plasmodiocarp , which are usually cushion-shaped, less often spherical to approximately cylindrical. The iridescent or shiny peridium is usually permanent. A columella is missing or greatly reduced.

The ray-like branched or network-like, loose to dense capillitium grows from the beginning of the fructification. The bulk of the spores are dark brown to almost black and have warty, prickly or reticulate sculptures.

distribution

The genus is known from Europe from Spain to Central Europe to the Kola Peninsula , in Asia (India, Japan) and North America (USA, Canada) as well as a single find from New Zealand. One species ( Diacheopsis metallica ) may also be native to German-speaking countries. Some species of the genus are nivicol, so they only fructify after a long-term snow cover. The possible habitats are diverse and range from mosses to deadwood, bark, living plants and others.

Systematics and research history

The genus was first described by Charles Meylan in 1930 , the type species is the Diacheopsis metallica , which he first described . The genus is difficult to distinguish from the genera Lamproderma and Colloderma and includes seventeen species:
