Novel taxa in Cladochytriales (Chytridiomycota): Karlingiella (gen. nov.) and Nowakowskiella crenulata (sp. nov.).

Six Nowakowskiella species from Brazil were identified and purified on corn meal agar (CMA) plus glucose and Peptonized Milk-Tryptone-Glucose (PmTG) media and placed into a phylogenetic framework for the genus. New sequence data are presented for four species: N. elongata, N. multispora , and N. ramosa and the new species N. crenulata . Our maximum likelihood and Bayesian analyses of combined 18S, 5.8S, and 28S subunits of nuc rDNA showed that Nowakowskiella is not a monophyletic clade because of the position of Nowakowskiella elongata , which is more related to Cladochytrium . We reclassify N. elongata as the type of a new genus, Karlingiella .
