Description
Genus Oligonema
Sporocarps usually densely crowded. Peridium membranous. Capillitium of simple or branched elaters, free from the base and capillitium and not forming a network , faintly decorated with spirals and sometimes warts and/or rings . Spore-mass yellow to ochre .
Physical Description
Species Oligonema flavidum
Plasmodium watery white, later yellow. Sporocarps sessile, bright yellow, densely clustered, subglobose when isolated, becoming obpyriform or subcylindric when massed, 0.2-0.5 mm broad, 0.5-0.8 mm tall. Peridium thin, shining or somewhat opaque , roughened or minutely papillate , with irregular fan-like markings, opening irregularly above. Capillitium usually sparse, of short to moderately long elaters, 10-300 µm long and 3-5 µm diam., irregular, swollen in places and occasionally branched, sculpured with minute warts arranged in indistinct spirals , the apices generally blunt , sometimes ending in one or more points . Spores 13-15 µm diam., with a coarse-meshed, often irregular but usually complete reticulum of narrow pitted bands .
