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

Abstract

Six <i>Nowakowskiella</i> 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: <i>N. elongata, N. multispora</i>, and <i>N. ramosa</i> and the new species <i>N. crenulata</i>. Our maximum likelihood and Bayesian analyses of combined 18S, 5.8S, and 28S subunits of nuc rDNA showed that <i>Nowakowskiella</i> is not a monophyletic clade because of the position of <i>Nowakowskiella elongata</i>, which is more related to <i>Cladochytrium</i>. We reclassify <i>N. elongata</i> as the type of a new genus, <i>Karlingiella</i>.
