Alternaria is a ubiquitous fungal genus that includes saprobic, endophytic and pathogenic species associated with a wide variety of substrates. In recent years, DNA-based studies revealed multiple non-monophyletic genera within the Alternaria complex, and Alternaria species clades that do not always correlate to species-groups based on morphological characteristics. The Alternaria complex currently comprises nine genera and eight Alternaria sections. The aim of this study was to delineate… 
New Species of Large-Spored Alternaria in Section Porri Associated with Compositae Plants in China
Multi-locus sequence analyses encompassing the internal transcribed spacer region of rDNA, glyceraldehydes-3-phosphate dehydrogenase, Alternaria major allergen gene, translation elongation factor 1-alpha (TEF1), and RNA polymerase second largest subunit (RPB2), revealed that the new species fell into sect.
Large-spored Alternaria pathogens in section Porri disentangled
Contrasting species boundaries between sections Alternaria and Porri of the genus Alternaria
The fungal genus Alternaria comprises a large number of asexual taxa with diverse ecological, morphological and biological modes ranging from saprophytes to plant pathogens, and association with host specificity seems a driving force for speciation.
Alternaria ershadii sp. nov. a new species isolated from wheat black head mold in Iran
It was revealed that Alternaria brassicifolii, which was recently described from Brassica rapa subsp.
Alternaria yunnanensis sp. nov., a New Alternaria Species Causing Foliage Spot of Rubber Tree in China
Molecular phylogenetic analyses based on ITS rDNA, GAPDH, and TEF1-alpha sequences demonstrate that the phytopathogen falls in the clade of the section Porri, being most closely related to A. sidae, A. sennae, and A. thunbergiae.
Distinction of Alternaria Sect. Pseudoalternaria Strains among Other Alternaria Fungi from Cereals
Species of the genus Alternaria are ubiquitous and frequently isolated from various plants, including crops. There are two phylogenetically and morphologically close Alternaria sections: the
Characterization of New Small-Spored Alternaria Species Isolated from Solanaceae in Algeria.
Detailed morphological characterizations and multi-locus phylogenetic analyses were performed on isolates of small-spored Alternaria species from north-western regions of Algeria, finding that they were able to produce leaf spot symptoms on tomato plants but with variable levels.
New species and new findings in Russia of Alternaria sect. Gypsophilae

Alternaria sect. Gypsophilae consists of 9 species that have been isolated from plants in the Caryophyllaceae . Findings of only one species, A. nobilis , in Russia were published previously. This
Phylogenomic analyses of Alternaria section Alternaria: A high-resolution, genome-wide study of lineage sorting and gene tree discordance
An overview and analysis of phylogenomic resources for Alternaria section Alternaria is presented and a list of candidate genes that may be developed into informative markers that are diagnostic for the main lineages are proposed.
Characterization of fungal species associated with cladode brown spot on Nopalea cochenillifera in Brazil
Differences in aggressiveness were observed among the species, with L. iraniensis and F. lunatum characterized as the most aggressive species, whilst F. verticillioides was described as the least aggressive.


The sections of Alternaria: formalizing species-group concepts
Phylogenetic analyses revealed eight distinct asexual lineages of Alternaria that cluster as the sister group to the asexual paraphyletic genus Ulocladium, while taxa with known teleomorphs currently circumscribed as Alternaria cluster among genera that also have representatives with knownteleomorphs.
Phylogeny and taxonomy of obscure genera of microfungi
Several families are shown to be polyphyletic within some orders, especially in the Capnodiales, Chaetothyriales and Pleosporales.
Sinomyces: a new genus of anamorphic Pleosporaceae.
Nimbya and Embellisia revisited, with nov. comb for Alternaria celosiae and A. perpunctulata
Data reveal that both Nimbya and Embellisia are polyphyletic as currently defined and taxonomic restructuring is necessary in order to resolve conflict between historical morphological and contemporary molecular-based phylogenies.
Asperisporium and Pantospora (Mycosphaerellaceae): epitypifications and phylogenetic placement
An examination of the type species of the anamorphic Asperisporium and Pantospora is presented and DNA sequence data from the ITS region and nLSU were analysed phylogenetically, placed into an evolutionary context within Mycosphaerellaceae, and compared to existing phylogenies.
Molecular taxonomy of the Alternaria and Ulocladium species from humans and their identification in the routine laboratory
The predictivity of a simplified polymerase chain reaction–restriction fragment length polymorphism procedure of rDNA for the recognition of the relevant species or species aggregates is established in a randomized test and its efficacy extended to the identification of sterile and meristematic Alternaria strains.
Molecular characterization of Embellisia and Nimbya species and their relationship to Alternaria, Ulocladium and Stemphylium.
DNA sequences from rDNA and protein-coding regions were determined and revealed that Embellisia and Nimbya clustered within a large monophyletic Alternaria-Nimbya-Embellisian-Ulocladium clade with Stemphylium as the sister taxon.
Phylogenetic lineages in the Capnodiales
It is concluded that the strictly plant pathogenic, nectrotrophic families evolved from saprobic ancestors (Capnodiaceae), which is the more primitive state.
Molecular phylogenetic relationships amongst Alternaria species and related fungi based upon analysis of nuclear ITS and mt SSU rDNA sequences
Phylogenetic analysis of the ITS and SSU rDNA sequences revealed that the Stemphylium spp.
