<i>Nigromargaritatarda</i> gen. et sp. nov. and distribution of an intron position class within <i>Pleosporales</i>.

ABSTRACT: Pleosporales, the largest order in Dothideomycetes, has a broad host range and inhabits host plants as epiphytes, endophytes, parasites and saprophytes. Trematosphaeriaceae is a monophyletic family in Pleosporales, composed of species of deviated ecological background and morphological traits. In this study, we described a new fungal taxon under Trematosphaeriaceae, based on root endophytic fungi recovered from the desert plant Gymnocarposprzewalskii in Gansu Province, China. The taxon is characterised by simple, aseptate conidia and pycnidia in unusually small sizes. Multilocus phylogenetic analysis, based on ITS, LSU, SSU and TEF sequences and a morphology study indicated that the taxon represented a new genus within the Trematosphaeriaceae
