Overview | |
Sporocarps densely clustered to heaped, sessile, hemispherical to pulvinate on a broad base, 0.5-2.0 mm diam., light brown or tan, covered with minute reddish dots. Hypothallus thick, leathery, colourless or light tan, continuous, weakly attached to the substrate. Peridium single, membranous, firm, persistent, dehiscing irregularly, the inner surface covered with refuse material which resembles numerous scattered crystals, covered with large bumps, crystals irregular but basically fusiform, 10-25 µm long. Capillitium extensive, not branched and anastomosed so not forming a distinct net, firmly attached to the peridium, light brown, intermittently bearing enlarged nodes filled with granular substance, nodes mainly fusiform, occasionally globose, size variable, up to 60 µm long, threads solid, smooth, predominantly slender, 1-2 µm diam., freely branching, especially at the nodes, the tips strongly attenuated where they are attached to the peridium. Spore-mass light brown. Spores pale yellow-brown, 8-10 µm diam., covered with a regular, complete reticulum, with 25-35 minute, distinct meshes per hemisphere, ornamentation delicate, up to 0.5 µm high. Plasmodium unknown. Nivicole.
