In most studies (Jeewon et al. 2003, Liu et al. 2010, Hu et al. 2007, Maharachchikumbura et al. 2011, 2012), species with dark concolourous median cells with knobbed apical appendages formed a distinct clade with high support, which is defined here as a novel genus, Pseudopestalotiopsis. Partial LSU sequence data confirm that Pseudopestalotiopsis is phylogenetically related to Neopestalotiopsis (Fig. 3), but these genera are also morphologically distinct. In Pseudopestalotiopsis the three median cells are the same colour (concolourous), whereas in Neopestalotiopsis these are versicoloured.
