''Prototrichia metallica'' is a slime mould species from the order Trichiida and the only species from the genus ''Prototrichia''. It is mainly distributed on mountains. ==Characteristics== ''Prototrichia metallica'' is a very variable species. The plasmodium is white. The fruit bodies are grouped densely.〔 They are orange brown to dull brown, occasionally pink, short stemmed or are lying on a heavily regenerated edge, rarely plasmodiokarp sporokarps with a diameter from 0.5 to 2.2 mm. The membranous peridium is transparently thin and shinily iridescent-coloured. Its surface is composed of a coarse mesh arrangement of wrinkled lines, along which it later divides into pieces.〔〔 The capillitium is often irregular, usually due to the presence of several yellow-brown, translucent spirally banded strands, which divide towards the outer end. The branches are often intertwined spirals, which sometimes form a network. Many of the outer ends are fused with the upper part of the peridium wall. The spirals are occasionally missing. The thorny spores are pink as mass,〔 orange-brown to brown, individually yellow and have a diameter from 10 to 13, rarely up to 15 µm. 〔 ==Habitat== ''Prototrichia metallica'' has been found in mountainous area of Tasmania, Europe, western North America and South America. It was first found in South America in 1976. It is a "nivicol", meaning that it grows on the snow line at the time of snowmelt.〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Prototrichia metallica」の詳細全文を読む スポンサード リンク
