Cercophora aquatica sp. nov. from a streambed in southern France

Chaudhary P., Fournier J. & Miller A. N. (2007) Cercophora aquatica sp. nov. from a streambed in southern France.

Sydowia 59 (2): 217–225.

Cercophora aquatica sp. nov., collected from a streambed in France, is described and illustrated. The morphological features of the fungus are glabrous ascomata which possess an outer areolate wall, asci with a double apical ring but which lack a subapical globule, and ascospores with long gelatinous appendages. It produced a Phialophora-like anamorph as well as blastoconidia in culture. It is compared to other Cercophora species characterized by glabrous ascomata. Cercophora species previously isolated from aquatic habitats are also discussed. Cercophora crustosa (Massee) P. Chaudhary, J. Fournier & A. N. Mill comb. nov. and Cercophora hydrophila (Kirschst.) P. Chaudhary, J. Fournier & A. N. Mill comb. nov. are proposed as new combinations.
