Overview | |
Phaneroplasmodium white. Sporocarpous to plasmodiocarpous, scattered, sessile on a restricted base, depressed, occasionally annulate, white. Sporocarps 0.5-1.5 mm diam., plasmodiocarps up to 10 mm in length. Hypothallus scanty, membranous, reddish brown. Peridium double, the outer layer consisting of scattered to compacted stellate lime crystals, the inner layer thin, membranous, iridescent, transparent. Dehiscence irregular. Columella, in sporocarps, an irregular calcareous mound attached to the central base of the fructifications, in plasmodiocarps forming a calcareous ridge with central attachment, occasionally with some portions free from the base of the fructifications. Capillitium rigid, abundant, consisting of flattened, brown tubules which radiate from the columella and attach firmly to the inner peridium by attenuated hyaline apices, the threads branched and anastomosed, connected by transverse tubules. Spore-mass dark purple brown. Spores purple brown, 11-14 µm diam., bearing irregularly spaced, coarse, often capitate, warts, the warts 1.0-1.5 µm tall, often united laterally to form short ridges, also bearing a reticulum with 2-5 meshes per hemisphere.
