CIFOR-ICRAF s’attaque aux défis et aux opportunités locales tout en apportant des solutions aux problèmes mondiaux concernant les forêts, les paysages, les populations et la planète.

Nous fournissons des preuves et des solutions concrètes pour transformer l’utilisation des terres et la production alimentaire : conserver et restaurer les écosystèmes, répondre aux crises mondiales du climat, de la malnutrition, de la biodiversité et de la désertification. En bref, nous améliorons la vie des populations.

CIFOR-ICRAF publie chaque année plus de 750 publications sur l’agroforesterie, les forêts et le changement climatique, la restauration des paysages, les droits, la politique forestière et bien d’autres sujets encore, et ce dans plusieurs langues. .

CIFOR–ICRAF publishes over 750 publications every year on agroforestry, forests and climate change, landscape restoration, rights, forest policy and much more – in multiple languages.

CIFOR–ICRAF addresses local challenges and opportunities while providing solutions to global problems for forests, landscapes, people and the planet.

We deliver actionable evidence and solutions to transform how land is used and how food is produced: conserving and restoring ecosystems, responding to the global climate, malnutrition, biodiversity and desertification crises. In short, improving people’s lives.

Taxonomy and phylogeny of dematiaceous coelomycetes

Exporter la citation

Coelomycetous fungi are an artificial taxonomic group which produce conidia inside a cavity i.e. conidiomata. Coelomycetes comprise about, 1000 genera and 7000 species, which can be endophytic, pathogenic or saprobic. Traditional classification of coelomycetes was previously based on morphology, such as the shape of conidiomata and mode of conidiogenesis, while it was treated as a distinct group i.e. Deuteromycotina. Sequence based taxonomic studies has been used to accommodate asexual fungi in a natural classification system, resolve generic boundaries of polyphyletic genera and species complexes, as well as establish asexual-sexual links. Nevertheless, most of genera lack sequence data, thus, morphology based identification is still important when introducing new genera or species. In this paper we illustrate, describe, and provide taxonomic notes for 235 dematiaceous coelomycetous genera, including five new genera viz. Apiculospora, Didymellocamarosporium, Melanocamarosporium, Melnikia and Paulkirkia. Phylogenetic analyses of combined sequence data are provided to show placements of dematiaceous coelomycetes in Dothideomycetes, Leotiomycetes and Sordariomycetes. One-hundred and fifty-two (65 %) of genera have sequence data, thus, their taxonomic placement in a natural classification system, is listed as an outline. However, 83 genera still lack sequence data, hence, they are treated as Ascomycota, genera incertae sedis. In addition, separate analyses are provided where better taxonomic resolution is needed. © 2016, School of Science.
