A-H Morphology of Amaurochaete atra (A–G — MYX 22638; H — MYX 16954). A — cortex surface; B, C —pseudocapillitium in reflected light; D — pseudocapillitium (LM); E, F — spores in different optical sections (LM); G — pseudocapillitium (SEM); H — spore (SEM). I–P Morphology of Amaurochaete tubulina (MYX 5409). I — cortex surface; J, K — pseudocapillitium in reflected light; L— pseudocapillitium (LM); M, N — spores in different optical sections (LM); O — pseudocapillitium (SEM); P — spores (SEM). Scale bars: A–C, I — 400 μm; D, G, L, O — 50 μm; E, F, M, N — 10 μm; H, P — 3 μm; J, K — 200 μm.

Phylogenetic position of the taxa in the order Stemonitidales with aethalioid sporophores, Brefeldia, Amaurochaete, and Symphytocarpus, is discussed. The genus Brefeldia is monotypic and is characterized by the presence of multicellular vesicles in the capillitium. Species of the genus Amaurochaete, with the exception of A. trechispora, are disting...

... atra (Alb. et Schwein.) Rostaf. The main distinguishing characters of this species are the presence of a long-lasting dark cortex (Fig. 4, A), which is covered outside with a network corresponding to the apexes of individual sporangia, as well as capillitium represented by separate thick filaments, abundantly branching in the upper part and not forming a dense network (Fig. 4, B, C, D, G). Spores are 12-15 μm in diameter, finely warted, with irregularly thickened wall (Fig. ...

Our specimens were characterized by a yellowish-brown cortex, on the surface of which the network corresponding to the sporangia boundaries was not visible. Spores were 12-14 μm in diameter finely ...

... main feature of the genus Brefeldia is the presence of chamber bodies in the structures of the capillitium (Fig. 6, B, C, I, J, see also Martin and Alexopoulos, 1969;Ing, 1999;Adamonytė, 2010). At the same time, unlike in Amaurochaete, the formation of a dense cortex is not characteristic for this genus (Fig 4, A, I). ...
