Muyocopron heveae sp. nov. and M. dipterocarpi appears to have host-jumped to rubber

Abstract

© 2019, German Mycological Society and Springer-Verlag GmbH Germany, part of Springer Nature. Muyocopron species were collected from dried branches of Hevea brasiliensis in Thailand. These were studied and compared with related taxa, based on the evidence from morphology and phylogenetic analyses of a combined LSU and SSU DNA sequence data. A new host record, Muyocopron dipterocarpi, and a new species, Muyocopron heveae, are described and illustrated. Phylogenetic analyses of combined LSU and SSU sequence data indicated that our strains cluster in Muyocopron and the new taxon forms a distinct clade as a new species in the genus. The germinating ascospores produced appressoria which suggests that it has an endophytic lifestyle. Muyocopron dipterocarpi appears to have host-jumped to rubber, which had been introduced to Thailand.
