Revising and allied genera in .

(, ) species are common soil-borne fungi, endophytes, epiphytes, and saprotrophs. Sexual morphs of spp were placed in the genus , which was further segregated into the six subgenera , , , , , and . However, with the end of dual nomenclature, became the single depository for sexual and asexual morph-typified species.

200 years of taxonomic confusion: Sporendonema and allies.

The genus Sporendonema (Gymnoascaceae, Onygenales) was introduced in 1827 with the type species S. casei for a red mould on cheese. Cheese is a consistent niche for this species.

Citizen science project reveals novel fusarioid fungi () from urban soils.

Soil fungi play a crucial role in soil quality and fertility in being able to break down organic matter but are frequently also observed to play a role as important plant pathogens. As part of a Citizen Science Project initiated by the Westerdijk Fungal Biodiversity Institute and the Utrecht University Museum, which aimed to describe novel fungal species from Dutch garden soil, the diversity of fusarioid fungi ( and other fusarioid genera), which are members of () was investigated. Preliminary analyses of ITS and LSU sequences from more than 4 750 isolates obtained indicated that 109 strains belong to this generic complex.

Phylogenetic Reassessment, Taxonomy, and Biogeography of and Similar Fungi.

The genus is a phialidic, dematiaceous hyphomycete known for its intriguing morphology and turbulent taxonomic history. This polyphasic study represents a new, comprehensive view on the taxonomy, systematics, and biogeography of and its relatives. Phylogenetic analyses of three nuclear loci confirmed that is polyphyletic.

: more than a node or a foot-shaped basal cell.

Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera in the terminal fusarioid clade of the family . Thus, an alternate hypothesis, namely a very broad concept of the genus was proposed. In doing so, however, a significant body of data that supports distinct genera in based on morphology, biology, and phylogeny is disregarded.

The genera , and (Chaetosphaeriaceae) are saprobes inhabiting decaying plant material. This study is based on an integrated morpho-molecular characterisation to assess their generic concepts and explore phylogenetic relationships. is revealed as polyphyletic, and species with 1-septate conidia and synnemata growing unilaterally along the seta are placed in the new segregate genus .

Phylogeny, Global Biogeography and Pleomorphism of .

() is a neglected, phialidic dematiaceous hyphomycete with striking phenotypic heterogeneity among its species. Little is known about its global biogeography due to its extreme scarcity and lack of records verified by molecular data. Phylogenetic analyses of six nuclear loci, supported by phenotypic data, revealed as highly polyphyletic, with species distributed among three distantly related lineages in Sordariomycetes.

Delimitation and phylogeny of , and introduction of and , genera nova.

(Chaetosphaeriaceae) is a phialidic dematiaceous hyphomycete with teleomorphs classified in . It is associated with significant variability of asexual morphological traits, which led to its broad delimitation. In the present study, six loci: nuc rDNA internal transcribed spacer region ITS1-5.

The Genera of Fungi - G6: , , , , and .

The Genera of Fungi series, of which this is the sixth contribution, links type species of fungal genera to their morphology and DNA sequence data. Five genera of microfungi are treated in this study, with new species introduced in , , and . The genus is emended and two new species and nine combinations are proposed.

Citizen science project reveals high diversity in Didymellaceae (Pleosporales, Dothideomycetes).

Fungal communities play a crucial role in maintaining the health of managed and natural soil environments, which directly or indirectly affect the properties of plants and other soil inhabitants. As part of a Citizen Science Project initiated by the Westerdijk Fungal Biodiversity Institute and the Utrecht University Museum, which aimed to describe novel fungal species from Dutch garden soil, the diversity of Didymellaceae, which is one of the largest families in the Dothideomycetes was investigated. A preliminary analysis of the ITS and LSU sequences from the obtained isolates allowed the identification of 148 strains belonging to the family.

Polyphasic identification of three new species in Alternaria section Infectoriae causing human cutaneous infection.

Background: Cutaneous phaeohyphomycosis is an emerging disease in immunocompromised patients, being Alternaria one of the most common genera reported as a causative agent. Species identification is not carried out mainly due to the complexity of the genus. Analysis of the ITS barcode has become standard for fungal identification, but in Alternaria it is only able to discriminate among species-groups or sections.
