Article 59.1, of the International Code of Nomenclature for Algae, Fungi, and Plants (ICN; Melbourne Code), which addresses the nomenclature of pleomorphic fungi, became effective from 30 July 2011. Since that date, each fungal species can have one nomenclaturally correct name in a particular classification. All other previously used names for this species will be considered as synonyms. The older generic epithet takes priority over the younger name. Any widely used younger names proposed for use, must comply with Art. 57.2 and their usage should be approved by the Nomenclature Committee for Fungi (NCF). In this paper, we list all genera currently accepted by us in Dothideomycetes (belonging to 23 orders and 110 families), including pleomorphic and non-pleomorphic genera. In the case of pleomorphic genera, we follow the rulings of the current ICN and propose single generic names for future usage. The taxonomic placements of 1261 genera are listed as an outline. Protected names and suppressed names for 34 pleomorphic genera are listed separately. Notes and justifications are provided for possible proposed names after the list of genera. Notes are also provided on recent advances in our understanding of asexual and sexual morph linkages in Dothideomycetes. A phylogenetic tree based on four gene analyses supported 23 orders and 75 families, while 35 families still lack molecular data

Phyllosticta species associated with freckle disease of banana

The identity of the casual agent of freckle disease of banana was investigated. The pathogen is generally referred to in literature under its teleomorphic name, Guignardia musae, or that of its purported anamorph, Phyllosticta musarum. Based on morphological and molecular data from a global set of banana specimens, several species were found associated with freckle disease. Phyllosticta maculata (from Southeast Asia and Oceania) is introduced as a new name for Guignardia musae, and an epitype is designated from Australia. Phyllosticta musarum (from India and Thailand) is shown to represent a distinct species, and the name is fixed by designation of an epitype from India. Guignardia stevensii is confirmed as distinct species from Hawaii, while Guignardia musicola from northern Thailand is shown to contain different taxa and is regarded as nomen confusum. Phyllosticta cavendishii is described as a new, widely distributed species, appearing primarily on Cavendish, but also on non-Cavendish banana cultivars

Phyllosticta spp. on cultivated Citrus in Australia

The occurrence of pathogenic and endophytic species of Phyllosticta on cultivated Citrus in Australia was investigated by DNA sequence analysis of specimens held in plant pathology herbaria and culture collections. Sequences of the internal transcribed spacer region (ITS1, 5.8S, ITS2), and partial translation elongation factor 1-alpha (TEF) gene of 41 Phyllosticta-like isolates from Citrus were compared to those sequences from the type specimens of Phyllosticta recorded from around the world. Phylogenetic analysis resolved all the sequences of Australian accessions into two major clades. One clade corresponded to P. citricarpa, which causes citrus black spot disease. The other clade contained P. capitalensis, which is a known endophyte of Citrus and many other plant species. All included herbarium accessions previously designated as Guignardia mangiferae are now designated P. capitalensis. No Australian isolates were identified as the newly described pathogens of citrus P. citriasiana or P. citrichinaensis, or the endophytes Guignarida mangiferae, P. brazilianiae, or P. citribraziliensis
