Dolabra nepheliae on rambutan and lychee represents a novel lineage of phytopathogenic Eurotiomycetes
Mycoscience 51 (4), 300-309
Abstract: Rambutan (Nephelium lappaceum) and lychee (Litchi chinensis) are tropical trees in the Sapindaceae that produce delicious edible fruits and are increasingly cultivated in tropical regions. These trees are afflicted with a stem canker disease associated with the ascomycete Dolabra nepheliae. Previously known from Asia and Australia, this fungus was recently reported from Hawaii and Puerto Rico. The sexual and asexual states of Dolabra nepheliae are redescribed and illustrated. In addition, the ITS and large subunit of the nuclear ribosomal DNA plus fragments from the genes RPB2, TEF1, and the mitochondrial small ribosomal subunit were sequenced for three isolates of D. nepheliae and compared with other sequences of ascomycetes. It was determined that D. nepheliae represents a new lineage within the Eurotiomycetes allied with Phaeomoniella chlamydospora, the causal agent of Petri grapevine decline.
