Slime molds of the genus Trichia , (red)

Trichia is a genus of slime molds from the order of the Trichiida . It is distributed worldwide and comprises fourteen species.

features

The stalked to sessile fruit bodies are sporangiate to almost plasmodiocarp . The one or two-layer peridium is either membranous or cartilaginous.

The scalp is flexible and consists of individual, non-grown threads ( elaters ) that are not or only weakly branched and seem to consist of two to five, rarely more, spirally twisted longitudinal ligaments. They are smooth to prickly on the surface and occasionally marked with vertical stripes. The spores are ocher to yellow-brown, brick-red or - as a spore mass - olive-colored, in transmitted light these colors turn out paler.

distribution

Trichia is widespread worldwide, the species mostly colonize dead wood . Trichia varia and Trichia favoginea are probably the most common species .

Systematics and research history

The genus was first described by Albrecht von Haller in 1768 , when he named Trichia gregaria sessilis, piriformis flava as the type species . This name, which is not valid according to the nomenclature rules , is now understood as Trichia ovata Persoon, which in turn is now synonymous with Trichia varia . The genus includes fourteen species, including:

In particular, the group of species with sessile and more or less yellow fruiting bodies ( T. persimilis , T. scabra , T. varia , T. lutescens , T. favoginea ) can only be reliably determined on the basis of their microscopic features, since the fruiting bodies are olive over yellow to golden brown can take on any color shade.
