sp. nov., A Novel Helminthosporoid Species Causing Foliage Blight of the Garden Plant in Brazil.

A severe leaf spot, turning to foliage blight, was observed on leaves of growing in a garden in Brazil (state of Rio de Janeiro) in 2015. A dematiaceous hyphomycete bearing a morphology typical of a helminthosporoid fungi was regularly found in association with diseased tissues. The fungus was isolated and pathogenicity was demonstrated through the completion of Koch's postulates.

Novel fungi from an ancient niche: cercosporoid and related sexual morphs on ferns.

The fern flora of the world () has direct evolutionary links with the earliest vascular plants that appeared in the late Devonian. Knowing the mycobiota associated to this group of plants is critical for a full understanding of the Fungi. Nevertheless, perhaps because of the minor economic significance of ferns, this niche remains relatively neglected by mycologists.

Towards a phylogenetic reappraisal of Parmulariaceae and Asterinaceae (Dothideomycetes).

Members of the Asterinaceae and Parmulariaceae are obligate biotrophic fungi with a pantropical distribution that grow in direct association with living plant tissues and produce external ascomata and bitunicate asci. These fungi are poorly known, with limited information about their taxonomic position in the Dothideomycetes. Much of what is known is conjectural and based on observation of morphological characters.

A new Inocyclus species (Parmulariaceae) on the neotropical fern Pleopeltis astrolepis.

During a survey for fungal pathogens associated with ferns in Brazil, a tar spot-causing fungus was found on fronds of Pleopeltis astrolepis. This was recognised as belonging to Inocyclus (Parmulariaceae). After comparison with other species in the genus, it was concluded that the fungus on P.
