Abstract
A new species of Memnoniella (Hypocreales, Stachybotryaceae) is described from decaying petioles of the subtropical giant fern Angiopteris lygodiifolia (Marattiales) from central Taiwan. The morphology of this fungus is described from the natural substrate and culture, based on light and scanning electron microscopy. The species is phylogenetically most closely related to M. dichroa, M. celtidis, M. oenanthes, and M. sinensis, which is supported by ITS, RPB2, TEF, and TUB sequence analysis. The new species M. pseudodichroa differs from those species by its longer conidia exceeding 13 µm. The misconception in the literature about collarettes on the conidiogenous cells in this genus is corrected.
