| phylogeny of discosia and seimatosporium, and introduction of adisciso and immersidiscosia genera nova. | discosia (teleomorph unknown) and seimatosporium (teleomorph discostroma) are saprobic or plant pathogenic, coelomycetous genera of so-called 'pestalotioid fungi' within the amphisphaeriaceae (xylariales). they share several morphological features and their generic circumscriptions appear unclear. we investigated the phylogenies of both genera on the basis of ssu, lsu and its nrdna and β-tubulin gene sequences. discosia was not monophyletic and was separated into two distinct lineages. discosia ... | 2011 | 22025806 |
