Trichiida

Arcyria nutans

The Trichiida are one of the five orders of slime molds in the group of Myxogastria.

Features

Types of Trichiida feature light, often yellow or red, rarely gray or light brown spore masses. The ever-present and often well-educated scalp has distinct markings on the surface generally. It consists of solid or tubular, smooth or sculptured filamentary elements. A columella missing always. The fruiting bodies contain no Kalkknötchen.

System

The order was first described in 1922 by Thomas Huston Macbride and includes 14 genera in two families with around 100 species:

• Family Dianemidae Calomyxa
• Dianema

• Family Trichiidae Trichia
• Arcyriatella
• Prototrichia
• Cornuvia
• Oligonema
• Calonema
• Arcyodes
• Arcyria
• Perichaena
• Metatrichia
• Hemitrichia
• Minakatella

Are common in Central Europe in particular representatives of Trichia, Hemitrichia and Arcyria.

Molecular Genetics Studies have shown that the order is the sister taxon of Liceida. The monophyly of the order is considered verified.
