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.

Taxonomic and phylogenetic placement of phaeodimeriella (Pseudoperisporiaceae, Pleosporales)

Exporter la citation

Phaeodimeriella is an epiphytic or pathogenic genus that occurs on plant surfaces associated with other fungi and belongs in the family Pseudoperisporiaceae (Dothideomycetes family, incertae sedis). The taxonomy of Phaeodimeriella has been problematic because of lack of molecular data and as some of the important morphological characters having not been reported. The present study clarifies the phylogenetic placement of Phaeodimeriella using fresh collections from northern Thailand. Two Phaeodimeriella species are characterized based on combined analyses of LSU, SSU, TEF and RPB2 sequence datasets. In the phylogenetic analyses, the two Phaeodimeriella species form a distinct lineage, adjacent to the Lentitheciaceae and Bambusicolaceae, in the order Pleosporales. The genus Phaeodimeriella is re-described and illustrated using modern concepts from fresh collections and provided with molecular data. The new species Phaeodimeriella cissampeli and P. dilleniae are introduced based on morphological characters, and molecular data is provided. The genus Lizonia is placed in Didymellaceae based on phylogenetic analysis. © 2016 Adac. Tous droits réservés.
