Abstract
A new species of Mahabalella B. Sutton & S. D. Patil was isolated from decaying leaves of an unidentified plant, during a survey in the Charles Darwin Ecological Refuge in Igarassu, Pernambuco, Brazil, in June 2018. The new species is morphologically distinguishable from the other Mahabalella species by the size of their conidia, conidiogenous cells and setae. In this study, the morphological descriptions, illustrations and cultural characteristics for Mahabalella pernambucana are provided, as well as a key to species of this genus. Total DNA from the isolate was extracted, and four genes were partially sequenced (nLSU, ITS cluster, TEF1 alpha, and beta tubulin). Based on the nLSU analysis, the phylogenetic position of the new species was determined within the Sordariomycetes, Ascomycota, as a sister genus to Neotracylla , in the Tracyllaceae family.
期刊介绍：
Experimental, theoretical and applied papers on all aspects of plant (including algae) and fungi biology are welcome. The submitted manuscript or its essential content must not have been published previously or be under consideration for publication elsewhere. Contributions should be substantial, written in high-quality English and show general interest. We expect that the submitted manuscript presents a great novelty in Botany, and this should attract a wide audience. Considering this, case studies are only considered if the narrative and implications are provided to be of general interest. Thus, manuscripts that report aspects of local interest are discouraged unless the implications of the findings are wide-reaching. Manuscripts with agronomic subjects are expected to contain a substantial amount of basic plant biology. Please see below some details for specific area.
