Description: Fruiting body a stalked sporangium, fasciculate in small- or medium-sized clusters, 4–8 mm tall, occasionally taller. Sporotheca cylindrical, obtuse, reddish brown, becoming paler with the disappearance of the spores, 0.2–0.3 mm in diameter. Stalk sometimes short but often exceeding one-third the total height of the entire sporangium. Hypothallus membranous, varying from pallid through dull red to nearly black. Peridium fugacious. Columella ending abruptly just below the apex of the sporotheca, often with a membranous expansion at the tip. Capillitium a loose network with many membranous expansions, surface net delicate, the meshes uneven, mostly small, with many spine-like free ends, often falling away rather quickly, especially above. Spores rich brown by transmitted light, verruculose, 7–9 µm in diameter. Plasmodium yellow, pallid, or white.
Habitat: Decaying wood.
Distribution: Cosmopolitan (Martin & Alexopoulos 1969). First reported from New Zealand by Macbride (1926), based on a specimen cited without naming a specific locality.
Notes: The distinguishing characteristics of this species are the membranous expansions in the capillitium.
