摘要：Species of Parmulariaceae are biotrophic, plant-parasitic microfungi that develop on the surface of living plants. We collected Aldona stella-nigra during a survey of foliar epiphytes in the Philippines and thus we restudied this poorly reported species around the world and re-examined some similar taxa. In this paper we re-describe and illustrate the type species of some similar genera, Aldona, Aldonata and Viegasella in Parmulariaceae which are leaf parasites and also provide details of the spermatial state of these unusual fungi. By re-illustrating the genera we anticipate fresh collections of these genera to be obtained for further studies so that molecular data can be analyzed to obtain a natural classification
