| Abstract: | Mariannaea aquaticola sp. nov. is described, illustrated, and compared with closely related taxa. Phylogenetic analysis of rDNA ITS and 28S sequences
show that Mariannaea aquaticola has affinity with Nectriaceae, which is in agreement with other Mariannaea species. Other morphologically similar genera such as Verticillium and Clonostachys are shown to be phylogenetically distant to Mariannaea. The generic concept of Mariannaea is discussed, and the affinity to Nectriaceous teleomorphs is suggested as additional generic character. A key to Mariannaea species is provided. |
