= Klebahnopycnis Kirchstein, Annls Mycol. 37: 120, 1939
Teleomorph: Unknown. Anamorph: Conidiomata stromatic, erumpent, cornute to cupulate, unilocular, setose, black; with a moderately developed basal textura epidermoidea, merging with a textura intricate at a higher level; excipulum well developed, of textura intricate in the outer layers giving rise to conidiomatal setae and merging toward the interior with an inner textura prismatica. Conidiomatal setae subulate, unbranched, septate, thickwalled, dark brown below. Conidiophores lining the cavity of the conidiomata, septate, branched, hyaline to very pale brown, smooth, invested in a thin layer of mucus. Conidiogenous cells discrete or integrated, subcylindrical to obclavate, monophialidic, hyaline, smooth. Conidia cylindrical, fusiform or ellipsoidal, euseptate, pale brown to almost colorless, smooth, bearing cellular appendages at both ends; appendages polar, arising as cellular extensions of the conidium body and separated from the latter by septa, branched or unbranched, attenuated, flexuous; basal appendage excentric (Adapted from Nag Raj 1993).
Ecology/Substrate/Host: Saprobe on dead material of plant.
Geographical distribution: Australia and China.
Description and illustration: Rao and Sutton (1976); Nag Raj (1993).
Notes: Hoehneliella was treated as member of both hyphomycetes and coelomycetes in literature due to different understanding of its conidiomata (Nag Raj 1993). Rao and Sutton (1976) redescribed the type species and concluded that the conidiomata of the fungus are cupulate and with brown setae, and the conidiophores arise from cells lining the wall. Nag Raj (1993) also examined the type specimen of the type species and described a bit more complex wall structure of conidiomata. Paramenisporopsis, typified by P. undulisetulata, has very similar conidiomata, conidiogenesis and conidial morphology and it might belong to the same genus as Hoehneliella (Matsushima 2003). Two species were discovered from China, and they can be distinguished by size and septation of conidia. In the phylogenetic analysis, Hoehneliella perplaxa, the type species of the genus Hoehneliella, forms a distinct linkage which is basal to Clades 1-8 and other genera in Clade 9 and well assigned to the Chaetosphaeriaceae. On the conidiomatal structure, H. perplaxa resembles Conicomyces, producing synnematous conidiomata with setae and well-developed excipulum (Nag Raj 1993; Seifert et al. 2011).
