Última Novel fungi from an ancient niche: cercosporoid and related sexual morphs on ferns Naturalis Guatimosim, E.; Schwartsburd, P.B.; Barreto, R.W.; Crous, P.W.. The fern flora of the world (Pteridophyta) 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. Cercosporoid fungi represent a large assemblage of fungi belonging to the Mycosphaerellaceae and Teratosphaeriaceae (Ascomycota) having cercospora-like asexual morphs. They are well-known pathogens of many important crops, occurring on a wide host range. Here, the results of a taxonomic study of cercosporoid fungi collected on ferns in Brazil are presented. Specimens were obtained...

Ano: 2016 URL: http://www.repository.naturalis.nl/record/611855 Towards a phylogenetic reappraisal of Parmulariaceae and Asterinaceae (Dothideomycetes) Naturalis Guatimosim, E.; Firmino, A.L.; Bezerra, J.L.; Pereira, O.L.; Barreto, R.W.; Crous, P.W.. 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. An assessment of the phylogenetic position of the Asterinaceae and Parmulariaceae is provided based on a phylogenetic analysis of the nrDNA operon (ITS) and the large subunit rDNA (LSU) sequence data obtained from fresh material of selected species collected in Brazil. Three key species were included and epitypified, namely Asterina melastomatis,...
