Overview
Sporocarps in small clusters, 1.3-2.5 mm total height. Sporothecae ovoid, ochraceous, c. 0.8 mm diam., 1-1.3 mm tall. Hypothallus common to a group. Stalk < 50% of the total height, 0.3-1.2 mm long, dark, sinuose-rugulose. Peridium fugaceous except for a glossy, deep calyculus that is 25-35% of the height of the unexpanded sporotheca, rather thick, membranous, pale ochraceous by TL, the calyculus margin rather smooth and regular, decorated inside with a small-meshed reticulum of low ridges and with papillae on some of the nodes in the upper part, basally the meshes strongly rounded and with small circular sub-perforations. Capillitium forming a lax net, easily breaking away as only a few ends are attached to the stalk apex, tubules c. 3 Ám diam. without and 6-7 Ám with the ornamentation of prominent, blunt spirally-arranged half-rings, the half rings and the parts between them roughened from dense, minute warts and scattered minute, delicate reticulations. Spore/capillitium-mass ochraceous. Spores 6-7 Ám diam.
