Enerthenema is a genus of slime mold fromthe Stemonitidae family . The genus includes four species, three of them are distributed in the northern hemisphere, one worldwide.
features
The fruiting bodies are stalked sporocarps , which are spherical to flattened spherical, the stalk consists of several intertwined fibers. The peridium lapses early, occasionally a very small collar remains at the outer end of the stem. The columella extends to the vertex and widens there like a funnel to form a disc.
The fork-like branched scalp grows from the disc of the columella and hangs down freely. The spores are brown to black in bulk.
distribution
The genus is known from Europe (Spain, France, Austria, Poland), Asia (Japan) and North America (USA, Canada), but one species ( Enerthenema papillatum ) is distributed worldwide. All species grow on dead wood , two species ( Enerthenema melanospermum , Enerthenema intermedium ) are nivicol, so they only fructify after a long-term snow cover.
Systematics and research history
The genus was first described by John Eddowes Bowman in 1830 , the type species is the Enerthenema elegans , which he first described and which was later synonymous with Enerthenema papillatum . The genus includes four species:
