... The cercosporoid fungi remains as the main group studied at the MCHUB with a total of 77 introduced taxa, distributed in genera Asperisporium, Cercospora, Mycovellosiella (=Passalora p.p.), Passalora, Phaeoramularia (=Passalora), Prathigada (=Passalora), Pseudocercospora, Sirosporium, and Zasmidium (=Stenella). Among them Pseudocercos- pora is the most important genus with 55% of the cercosporoid fungi described, followed by Passalora, and Cercospora (Table 4) DIANESE et al. 2008;DORNE-LO-SILVA & DIANESE 2003;DORNELO-SILVA et al. 2007;HERNÁNDEZ--GUTIÉRREZ & DIANESE 2008HER-NÁNDEZ-GUTIÉRREZ et al. 2014, 2015INÁCIO & DIANESE 1998). ...
In this review, we present an historic account of the work on the diversity of fungi associated with plants of the Cerrado Biome, including an overview of the studies carried out by the research group of the Mycological Collection connected to the Herbarium UB (Universidade de Brasília), and the rust fungi in Herbarium IBI (Instituto Biológico, São Paulo). The contributions to Cerrado mycology from the early 19th century to the present days were highlighted. Illustrative maps were included to show the geographical distribution of the main fungal groups, associated with native plants of the Cerrado, belonging to the five predominant orders: Pucciniales (rust fungi), Phyllachorales (tar-spot fungi), Capnodiales (cercosporoid fungi: Family Mycosphaerellaceae), as well as Meliolales and Asterinales (black mildews).
... The coelomycetes described from multiple hosts in the Cerrado belong to 11 genera: Coniella (Dianese et al. 1993b), Phloeosporella (Dianese et al. 1993a(Dianese et al. , 1993c, Phyllosticta, Dinemasporium, Harknessia, and Pseudothiopsella (Furlanetto and Dianese 1997), Fumagospora, Polychaeton, and Septoria (Inácio and Dianese 1998), Phomopsis (Inácio et al. 1999), and Oswaldina (Dianese et al. 1994). ...
Megacoelomyces (type species: Megacoelomyces sanchezii), an ascomycete asexual morph infecting Myrcia fenzliana (Myrtaceae) from the Brazilian Cerrado, is described as a new genus in the Phaeosphaeriaceae (Pleosporales, Dothideomycetes, Ascomycota), based on multilocus phylogeny (three nuclear ribosomal DNA and two protein-coding genes) in addition to morphological (light and scanning electron microscopy) and ecological data.
... These fungi have been studied by several authors in Brazil (Batista & al., cf. Silva & Minter 1995;Braun & Freire 2004;Chupp 1954;Crous & Braun 2003;Crous & Wingfield 1997;Crous & al. 1999;Fernandes & al. 2013;Hernández-Gutiérrez & Dianese 2008, 2009Hernández-Gutiérrez & al. 2014, 2015Inácio & Dianese 1998Inácio & al. 1996;Pereira & Barreto 2006;Viégas 1945). They have been reported as plant pathogens on several hosts including different economically important crops, and some cercosporoid fungi are also used for biological control of weeds (Farr & Rossman 2019, Groenewald & al. 2013, Hanada & Gasparotto 2002, Mendes & Urben 2019, Mendes & al. 1998, Pereira & Barreto 2006, Pons 1987, Spegazzini 1910. ...
Using stereo- and light microscopy, two leaf-spotting cercosporoid fungi, collected from areas of the Brazilian Atlantic Forest in the states of Minas Gerais and Rio de Janeiro, were shown to represent two new species ( Pseudocercospora seropedicensis on Solanum asperum and P. solani-cernui on S. cernuum ), which are herein described and illustrated.
... Starting in 1994(Medeiros & Dianese 1994), a sequence of papers was published describing new species of cercosporoid fungi from the Cerrado. In these publications, a new species belonging in Parastenella, four in Cercospora, 22 in Passalora, 31 in Pseudocercospora, and fi ve in Stenella were described ( Dianese & Câmara 1994;Inácio & Dianese 1998Furlanetto & Dianese 1999;DorneloSilva & Dianese 2003;Dornelo-Silva et al. 2007;Dianese et al. 2008;Hernández-Gutiérrez & Dianese 2008, 2009, 2014aHernández-Gutiérrez et al. 2014). Four of the species previously assigned to Stenella are now reallocated to Zasmidium. ...
... During the last decades, several papers have dealt with cercosporoid fungi from Brazil (Crous et al. 1997Crous et al. , 1999Crous et al. , 2011 Crous & Câmara 1998; Barreto et al. 1999). The majority of species have been reported in other biomes, mainly cerrado (Dianese & Câmara 1994; Medeiros & Dianese 1994; Inácio et al. 1996; Dianese et al. 1998 Dianese et al. , 1999 Braun et al. 1999; Furlaneto & Dianese 1999; Inácio & Dianese 1998 Braun & Freire 2002, 2004 Dornelo-Silva & Dianese 2003; Dornelo-Silva et al. 2007; Hernández-Gutiérrez & Dianese 2008 Freire & Braun 2009). Sporadic works on cercosporoid fungi in Atlantic Forest fragments revealed some new, undescribed species, such as the first reports of cercosporoid fungi on hosts of the family Siparunaceae and a revision of cercosporoids on Piperaceae (Pereira et al. 2003Pereira et al. , 2007 Vieira & Barreto 2004; Pereira & Barreto 2005 Soares & Barreto 2005; Rocha et al. 2007 Rocha et al. , 2008 Rocha et al. , 2010, 2010, 2011 Alves et al. 2008; Macedo & Barreto 2008; Almeida et al. 2010; Alves & Barreto 2010; Machado et al. 2012; Silva et al. 2012). ...
Three new cercosporoid hyphomycetes were found associated with leaf spots on three host families in a stretch of Atlantic Forest in Viçosa, Minas Gerais, Brazil: Pseudocercospora aurelianae sp. nov. on Aureliana velutina (Solanaceae), P. vicosae sp. nov. on Eupatorium sp. (Asteraceae), and Passalora rolliniae sp. nov. on Rollinia sylvatica (Annonaceae). These three species are fully described, illustrated, discussed, and compared with allied species in the present work.

Notes: Inácio & Dianese (1998) described Septoria tabebuiaeimpetiginosae on T. impetiginosa (conidia 25-67 × 2-4 µm, 2-6-septate), and also compared this species to S. tabebuiae (18-40 × 1.7-2.5 µm, aseptate conidia) on T. berteroi, and S. cucutana (34-40 × 0.8-1 µm) on T. pentaphylla and T. spectabilis. Furthermore, they also referred to an undescribed species Ferreira (1989) mentioned on T. serratifolia in Viçosa, Minas Gerais, which is named as S. tabebuiae-serratifoliae in the present study. ...

Septoria represents a genus of plant pathogenic fungi with a wide geographic distribution, commonly associated with leaf spots and stem cankers of a broad range of plant hosts. A major aim of this study was to resolve the phylogenetic generic limits of Septoria, Stagonospora, and other related genera such as Sphaerulina, Phaeosphaeria and Phaeoseptoria using sequences of the the partial 28S nuclear ribosomal RNA and RPB2 genes of a large set of isolates. Based on these results Septoria is shown to be a distinct genus in the Mycosphaerellaceae, which has mycosphaerella-like sexual morphs. Several septoria-like species are now accommodated in Sphaerulina, a genus previously linked to this complex. Phaeosphaeria (based on P. oryzae) is shown to be congeneric with Phaeoseptoria (based on P. papayae), which is reduced to synonymy under the former. Depazea nodorum (causal agent of nodorum blotch of cereals) and Septoria avenae (causal agent of avenae blotch of barley and rye) are placed in a new genus, Parastagonospora, which is shown to be distinct from Stagonospora (based on S. paludosa) and Phaeosphaeria. Partial nucleotide sequence data for five gene loci, ITS, LSU, EF-1α, RPB2 and Btub were generated for all of these isolates. A total of 47 clades or genera were resolved, leading to the introduction of 14 new genera, 36 new species, and 19 new combinations.

Numerous cercosporoid leaf-spotting hyphomycetes have been continuously collected in Venezuela and several new species and records have been published. Additional specimens, including various collections made between 1966 and 1970 in Cuba and Venezuela, are treated in this paper. The latter material is now housed at K (previously deposited at IMI as "Cercospora sp."). Venezuelan collections made between about 1990 and 2012 (most of them since 2006) are now deposited at HAL. Several species are new to Venezuela, some new host plants are included, and the following new species and new varieties are introduced: Cercospora hadroanthi, Passalora emmeorhizae, P. melochiae, Pseudocercospora andirae, P. cordiae-alliodorae, P. cordiigena, P. crescentiae, P. gonolobicola, P. jahnii var. amaculata, P. pehriicola, P. rauvolfiae-tetraphyllae, P. trichophila var. punctata, Zasmidium asclepiadis. The new combinations Pseudocercospora trichophila var. solani-asperi and Zasmidium gongronematis are proposed.
