Overview | |
Myxocarps gregarious to scattered, sessile, primarily sporocarpous, 0.1-0.4 mm diam., subglobose to depressed, white, occasionally with straight or rarely branched plasmodiocarps 0.08-0-16 mm wide and up to 1.5 mm long. Hypothallus membranous. Peridium appearing as a single, eggshell-like layer composed of a thin membranous, colourless layer charged with crystals. Dehiscence usually basal, separating the peridium as a unit. Columella absent. Capillitium arising mainly from and remaining attached to the base, consisting of sub-parallel, hyaline threads, 1 µm diam., sometimes transversely connected or branched and anastomosed, frequently bearing white, crystalline bodies up to 10 µm wide and 750 µm long trapped within threads, or appearing physaroid with widely scattered, irregular, calcareous nodes connecting 2 or 3 threads. Spore-mass black. Spores dark brown, subglobose, (9-)10(-11) µm diam., the surface uniformly covered by truncate processes, appearing echinulate with light microscopy, and encircled by a conspicuous ± equatorial ring, apiculate in optical section. Plasmodium colourless to milky white.
