Abstract
BackgroundDuring the survey of pathogenic fungi on medicinal plant leaves in Yunnan Province, China, two Cladosporium-like taxa were isolated from leaf spots of Parispolyphylla. Based on morphological characteristics and phylogenetic analysis of combined ITS, TEF1-α and ACT genes, two new species were discovered.New informationTwo new species Cladosporiumyunnanensis and C.paris are introduced, the detailed descriptions and illustrations are provided. Morphology of the two new species is compared with other related Cladosporium species. This study widens the host diversity of the genus Cladosporium.
Highlights
Cladosporium is one of the largest and most heterogeneous genera of hyphomycetous fungi (Dugan et al 2004)
In our study, based on the typical morphological features (Schubert et al 2007, Zalar et al 2007, Dugan et al 2008, Bensch et al 2010), Cladosporium yunnanensis and C. paris belong to the C. cladosporioides and C. herbarum species complex, respectively
Multi-gene phylogenetic analysis (ITS, translation elongation factor 1-α (TEF1-α) and ACT) can further prove the taxonomy of the two species in Cladosporium, which is consistent with the result by morphological features
