Trichia varia is a cosmopolitan kind of slime molds from the order of trichiida .
description
The plasmodium is white. The fruiting bodies , which form small to large clusters, are mostly sessile, occasionally short-stalked sporocarp , rarely found plasmodiocarpart forms. The ocher-yellow to yellow-brown or olive-colored, shimmering to glossy fruit bodies are spherical, obovate, club-shaped to slightly elongated and measure 0.5 to 0.9 millimeters in diameter.
The hypothallus is thin, inconspicuous, colorless to brown and membranous to horn-like, the stalk - if present - up to 0.5 millimeters high, dark brown to black, thickened and grooved. The membranous peridium is yellow, shiny or covered with brown thickenings. The yellow to ocher-colored capillitium consists of unwaxed, mostly unbranched, 3 to 5 micrometers thick and long elaters that carry two to three irregularly and loosely wound, protruding spiral strands. Their ends are curved, tapering to a point and are around twice as long as their diameter. The spore mass is yellow to ocher-colored or orange-yellow, in transmitted light pale yellow. The spores are 12 (rarely from 11) to 14 micrometers in diameter and slightly warty.
distribution
The species is distributed worldwide. It is usually found on dead wood , but occasionally also on the bark of living trees.
