Boedjin | | | | |
Labyrinthomyces varius (Rodway) Trappe, Mycotaxon, 9 (1): 320 (1979).
Basionym Stephensia varia Rodway, Pap. Proc. Roy. Soc. Tasmania, 1897: 129 (1897).
Diagnosis Stephensia varia, n.s., subterranean, irregularly spherical. Peridium rather thick, sub-cartilaginous. Gleba of one or more broad contorted hymenial cells or tubes in a pithy fiberoid trama. Asci narrow, cylindrical. Paraphysis numerous linear. Sporidia spherical, smooth, hyaline, 20 u. Very variable in size and proportionate development of tubes and trama. When small, ½ -¾ in. tube often single and not very contorted, with copious trama. When about 1 in. tubes fairly numerous, trama reduced, the tuber being then of a firmer consistency. In specimens about 2 in. diameter the tubes are very numerous and large (¼ in.), and trama very slight. These three forms may be persistently distinct, but the asci and sporidia not differing would lead one to infer they are forms of one plant. The small softer form is much sought by larvae of small insects, the empty peridium is often found lying on the surface of the soil.
