PDD 6343, 17578, 74400.

Fruiting body a sessile sporangium, crowded, globose or turbinate, dull orange or golden brown, 0.5–0.7 mm in diameter. Hypothallus well-developed, contiguous for a group of sporangia, membranous, colourless to more commonly brown. Peridium delicate, smooth, shining. Capillitium deep yellow to rusty orange, the elaters simple, long, 5–6 µm in width, bearing 3 or 4 closely wound, regular, spinulose spiral bands, the apices short, acuminate. Spores yellow or orange in mass, yellow by transmitted light, the surface marked by a delicate, fine-meshed reticulum, 10–12 µm in diameter. Plasmodium white.

Apparently cosmopolitan (Martin & Alexopoulos 1969). First reported from New Zealand by Rawson (1937), based on a specimen collected in Southland. Also known from Auckland and South Canterbury.

The orange-yellow spore mass, elaters with densely spinulose spiral bands, and faintly reticulate spores are the most important characteristics that can be used to separate Trichia scabra from other members of the genus that produce sessile sporangia.
