“…The type species of Cercospora , Cercospora depazeoides (= Cercospora penicillata ) (see Braun 1995 : 41), is a common, widespread cercosporoid fungus on elderberry. Re-examinations of type material and numerous other collections revealed that this species is conspecific with Pseudocercospora sambucigena ( Braun et al. 2015 ), which is a proven species of Pseudocercospora ( Crous et al.…”

“…These fungi represent a very large heterogeneous group for which the existing monographs ( Chupp, 1954 , Braun, 1995 , Braun, 1998 , Crous and Braun, 2003 ) are in urgent need of revision (e.g. Braun et al., 2013 , Braun et al., 2014 , Braun et al., 2015 ). With the introduction of phylogenetic analyses based on DNA sequences, the Mycosphaerellaceae has been more narrowly defined with names of asexual genera now being used to identify morphologically distinct monophyletic clades, e.g.…”

The Mycosphaerellaceae represent thousands of fungal species that are associated with diseases on a wide range of plant hosts. Understanding and stabilising the taxonomy of genera and species of Mycosphaerellaceae is therefore of the utmost importance given their impact on agriculture, horticulture and forestry. Based on previous molecular studies, several phylogenetic and morphologically distinct genera within the Mycosphaerellaceae have been delimited. In this study a multigene phylogenetic analysis (LSU, ITS and rpb2) was performed based on 415 isolates representing 297 taxa and incorporating ex-type strains where available. The main aim of this study was to resolve the phylogenetic relationships among the genera currently recognised within the family, and to clarify the position of the cercosporoid fungi among them. Based on these results many well-known genera are shown to be paraphyletic, with several synapomorphic characters that have evolved more than once within the family. As a consequence, several old generic names including Cercosporidium, Fulvia, Mycovellosiella, Phaeoramularia and Raghnildiana are resurrected, and 32 additional genera are described as new. Based on phylogenetic data 120 genera are now accepted within the family, but many currently accepted cercosporoid genera still remain unresolved pending fresh collections and DNA data. The present study provides a phylogenetic framework for future taxonomic work within the Mycosphaerellaceae.

Rice is the source of staple food for most Indonesian people. The demand is continually increasing as the impact of increasing the people population. Sustainable development of rice must be done by the government. One of the problems in rice production is narrow brown leaf spot disease caused by Cercospora oryzae. This study aimed to determine the resistance of some varieties of rice to C. oryzae. The study was conducted on a field scale with natural inoculation and greenhouse with artificial inoculation using C. oryzae conidia suspension density of 105 conidia ml-1. The parameters observed, were incidence of disease, disease severity, the rate of infection, Area Under the Disease Progress Curve (AUDPC), and crops production. The result showed in the field that rice varieties of Gagak Hitam and Pandan Wangi were categorized as moderat resistant, while IR64, Inpari4, Sunggal and Ciherang showed high susceptible to C. oryzae. The results of greenhouse study showed that Hitam Gagak and Pandan Wangi rice varieties were categorized as resistant and IR64, Inpari4, Sunggal, Ciherang were moderate resistant (RR) against C. oryzae. The resistance of rice varieties affected by the interaction between pathogen genes that determine virulence and host genes that determine the resistance of the host plant.

The present paper continues a series of comprehensive taxonomic treatments of cercosporoid fungi (formerly Cercospora s. lat.), belonging to the Mycosphaerellaceae (Ascomycota). The fourth contribution of this series initiates treatments of cercosporoid fungi on dicots and comprises species occurring on hosts belonging the the families Acanthaceae, Actinidiaceae, Adoxaceae, Aizoaceae, Altingiaceae, and Amaranthaceae. The species are described and illustrated in alphabetical order under the particular cercosporoid genera, supplemented by keys to the species concerned. A detailed introduction, a survey of currently recognised cercosporoid genera, a key to the genera concerned, and a discussion of taxonomically relevant characters were published in the first part of this series. The following taxonomic novelties are introduced: Cercospora blepharidicola nom. nov., C. celosiigena sp. nov., C. justiciae-adhatodae sp. nov., C. justiciigena nom. nov., C. sambucicola nom. nov., C. thunbergiigena nom. nov., Cercosporella pseudachyranthis comb. nov., Pseudocercospora cyathulae comb. nov., P. depazeoides comb. nov., P. varia var. viburni-sargentii var. nov., P. viburnicola sp. nov., P. viburni-erosi sp. nov., and P. viburni-nudi sp. nov.
