Echinostelium fragile Nann.-Bremek. 1961

DWM 3067, 3133

Fruiting body a stalked sporangium, scattered to gregarious, 100–150 µm tall. Sporotheca globose, erect or nodding, pale grey to yellowish pink, 30–50 µm in diameter. Stalk translucent, pale yellow, 70–130 µm long. Hypothallus inconspicuous. Peridium persisting in mature fruiting bodies as a collar at the base of the sporangium. Columella cylindrical to fusiform, 5–10 µm long, dark olive brown by transmitted light. Capillitium absent. Spores pink in mass, hyaline to greyish or yellowish pink by transmitted light, minutely roughened, with a diffuse thinner area on one side, 11–14 µm in diameter. Plasmodium translucent pink.

This species has been recorded from Australia (Mitchell 1995), Europe (Nannenga Bremekamp 1991), and North America (Martin & Alexopoulos 1969; Whitney 1980). First reported from New Zealand by Mitchell (1992), based on specimens appearing in moist chamber culture on bark samples of Cedrus deodora and an unidentified tree. The bark samples were collected in Bay of Plenty and North Canterbury

Martin & Alexopoulos (1969), Keller & Brooks (1977), Whitney (1980), Nannenga Bremekamp (1991), Neubert et al. (1993), Lado & Pando (1997), Ing (1999).

As the smallest of the three species of Echinostelium known from New Zealand, E. fragile is easily overlooked in moist chamber cultures.
