Prototrichia metallica

Prototrichia metallica is a species of slime mold from the order of Trichiida and the only species of the genus Prototrichia. It is mainly used in mountains.

Description

Prototrichia metallica is considered very variable Art The Plasmodium is white. The fruiting bodies are in dense groups. They are orange -brown to dull brown, sometimes pink, Short-stalked or a strongly tapered approach sessile, rarely nearly plasmodiokarpe Sporokarpe with a diameter from 0.5 to 2.2 millimeters. The membranous peridium is translucent colored thin and shiny iridescent. Its surface consists of coarse mesh arranged, wrinkled lines along which it breaks down later in items.

The often irregular scalp is usually from numerous yellow-brown, massive translucent, spirally banded threads that share vielfädig toward the outer end. The branches are often intertwined spirals with one another, sometimes they form a network. Many of the outer ends are fused to the upper part of the Peridialwand. The spirals are missing occasionally. The spiny spores are yellow mass as pink, orange -brown to brown, single and have a diameter of 10 to 13, rarely up to 15 microns.

Dissemination

Prototrichia metallica is known from mountain areas of Tasmania, Europe and western North America. Finds from South America were not known until 1976; but it is considered beyond doubt that they will be there also discovered. It is regarded as " nivicol ", that is, it grows when the snow melt at the snow line.

Systematics and history of research

The species was first described in 1859 as Trichia metallica by Miles Joseph Berkeley, the genus in 1876 by Jozsef Tomasz Rostafinski. Prototrichia has long been provided to the Dianemidae, sometimes even regarded as a separate family Prototrichiaceae. Since the late 1960s, however, the view has prevailed that they are part of Trichiidae. Charles Meylan 1921 described another type Prototrichia schroeteri, the name is generally regarded as a synonym, Nowotny believes that it is possible that hides behind a separate type.
