Overview | |
Plasmodiocarpous or occasionally sporocarpous, sessile, pulvinate to effused, up to c. 3 mm wide and 6 mm long, 60-100 µm high, white or tinted buff especially at the margin. Peridium of two closely adherent layers, pale buff within, the outer layer eggshell-like, the inner membranous, translucent and pale. Columella absent, the floor of the myxocarp slightly thickened, limeless, glossy, buff, often ± iridescent. Capillitium of sparse, slender, rigid, ± parallel, pale to purplish brown threads extending from the base and broadly attached to to the upper peridium, simple but sometimes bifurcate or branched and anastomosed, often with expanded axils, 1-3(-5 ) µm diam., and nodular thickenings, the extremities hyaline. Spore-mass dark brown. Spores violaceous brown, thick-walled, clustered into groups of 4-25, ovoid to sub-globose, the exposed outer surface with spines up to c. 1 µm high which are often fused at their bases, elsewhere nearly smooth, 11-12 x 12-14 µm diam.
