Neopestalotiopsis Maharachch., K.D. Hyde & Crous 2014
This genus is related to Pestalotiopsis but differs in the 3 median cells of the conidia having a variable colouration (e.g. some of them are darker then the others) and the conidiophores being small and indistict. The acervuli are typically black and are arranged in concentric rings.
Maharachchikumbura et al. (2014) have provided the following description of the genus:
Conidiomata acervular or pycnidial, subglobose, globose, clavate, solitary or aggregated, dark brown to black, immersed to erumpent, unilocular or irregularly plurilocular; exuding dark brown to black conidia in a slimy, globose mass. Conidiophores indistinct, often reduced to conidiogenous cells. Conidiogenous cells discrete, cylindrical, ampulliform to lageniform, hyaline, smooth, thin-walled; conidiogenesis initially holoblastic, becoming percurrent to produce additional conidia at slightly higher levels. Conidia fusoid, ellipsoid to subcylindrical, straight to slightly curved, 4-septate; basal cell conic to subcylindrical, with a truncate base, hyaline or pale brown to olivaceous, thin and rugose to smooth-walled; three median cells doliiform, wall rugose to verruculose, versicoloured, septa darker than the rest of the cell; apical cell hyaline, conic to cylindrical, thin- and smooth-walled; with tubular apical appendages, one to many, filiform or attenuated, flexuous, branched or unbranched; basal appendage single, tubular, unbranched, centric.
