Oligonema verrucosum

Sporocarps aggregated, stalked, usually several sporocarps united by the stalks, 1.6–2.6 mm in total height. Hypothallus membranous, common to a group of sporocarps, effuse, opaque. Stalk weak, flattened, longitudinally grooved, 0.8–1.2 mm long, 0.1–0.15mm wide, yellow. Sporotheca obovoid, 0.8–1.4 × 0.5–1 mm, yellow to orange yellow. Peridium membranous, single, partially evanescent, remaining at the basal part as a calyculous, thin, fragile, the inner side papillate, dehiscence irregular. Capillitium an elastic network of threads arising from the base of the sporotheca, threads of 5–7 μm in diameter, yellow by TL, flexuous, scarcely branched, with acute free ends of 10–12.5 μm long, ornamented with 4 or 5 spiral bands. Spores free, yellow in mass, light yellow by TL, globose, 11–12.5 μm in diameter, reticulate

This species often forms large fruitings in moist temperate forests of the Southern Hemisphere but is surprisingly rare in comparable forests in the Northern Hemisphere.
