Novel fungi from an ancient niche: cercosporoid and related sexual morphs on ferns
Provedor de dados: Naturalis Digital Academic Repository
Autores: 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...

Exploring fungal mega-diversity: Pseudocercospora from Brazil
Provedor de dados: Naturalis Digital Academic Repository
Autores: Silva, M.; Barreto, R.W.; Pereira, O.L.; Freitas, N.M.; Groenewald, J.Z.; Crous, P.W.
Although the genus Pseudocercospora has a worldwide distribution, it is especially diverse in tropical and subtropical countries. Species of this genus are associated with a wide range of plant species, including several economically relevant hosts. Preliminary studies of cercosporoid fungi from Brazil allocated most taxa to Cercospora, but with the progressive refinement of the taxonomy of cercosporoid fungi, many species were relocated to or described in Pseudocercospora. Initially, species identification relied mostly on morphological features, and thus no cultures were preserved for later phylogenetic comparisons. In this study, a total of 27 Pseudocercospora spp. were collected, cultured, and subjected to a multigene analysis. Four genomic regions...

Reappraisal of the genus Alternariaster (Dothideomycetes)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Alves, J.L.; Woudenberg, J.H.C.; Duarte, L.L.; Crous, P.W.; Barreto, R.W.
Alternariaster was erected in 2007 to accommodate Alternaria helianthi, a fungal species known to cause leaf spots on Helianthus annuus (sunflower). It was segregated from Alternaria based on conidial morphology. Recently an unknown alternaria-like dematiaceous fungus was found associated with leaf spots on Bidens sulphurea (yellow cosmos) in Brazil. Based on a multi-gene phylogeny of parts of the ITS and LSU genes, this fungus was placed within the Leptosphaeriaceae with Alternariaster helianthi as its closest neighbour. Additional genes sequenced, RPB2 and GAPDH, confirmed this close relationship. The fungus on B. sulphurea has smaller conidia, 50–97.5 × 12.5–20 μm, compared to Al. helianthi, 80–160 × 18–30 μm, and lacks oblique or transverse septa which...

Towards a phylogenetic reappraisal of Parmulariaceae and Asterinaceae (Dothideomycetes)
Provedor de dados: Naturalis Digital Academic Repository
Autores: 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,...
