Johnalcornia gen. et. comb. nov., and nine new combinations in Curvularia based on molecular phylogenetic analysis
Australasian Plant Pathology 43 (6), 589-603
Abstract: An examination of ex-type and authentic cultures of 34 species of Bipolaris and Curvularia by phylogenetic analysis of four loci (EF-1alpha, GAPDH, ITS and LSU) resulted in nine new combinations in Curvularia, as well as new synonymies for some species of Bipolaris and Curvularia. Lectotypes are designated for Bipolaris secalis and Curvularia richardiae, and an epitype is designated for Curvularia crustacea. A new monotypic genus, Johnalcornia, is introduced to accommodate Bipolaris aberrans, which clusters sister to the newly described Porocercospora. Johnalcornia differs morphologically from this taxon by producing distinctive conidia-like chlamydospores as well as comparatively thick-walled, geniculate conidiophores, with conidiogenous cells that have conspicuous scars. Johnalcornia further differs from related genera by forming the second conidial septum in the apical cell.
