Abstract
Two species of dematiaceous hyphomycetes parasitic on leaves of Maianthemum gigas or M. paniculatum (Liliidae) in tropical mountain rainforests in Western Panama are described as new. One species is morphologically intermediate between Periconiella, Pseudocercosporidium, and Stenella. It is tentatively accommodated in Periconiella because of strongly branched conidiophores and verruculose external hyphae. It differs from other Periconiella species by stromata embedded in the substomatal chamber of the leaves. The other species belongs to Pseudocercospora and is described as new since no similar species of Pseudocercospora is known on species of Maianthemum or related genera. Both species are illustrated in detail with drawings based on light microscopy and images based on scanning electron microscopy. © 2007 German Mycological Society and Springer.
