MATERIAL STUDIED. — Brazil . Mato Grosso do Sul , Campo Grande, UFMS Campus, on wood, Aptroot & Muxfeldt 83272 . NOTES New record for Mato Grosso do Sul . For a description, see Yacharoen et al . (2015) . The species is often synonymized with the type species of the genus, butYacharoen et al . (2015) argue against this (q.v.) and prefer to keep the tropical material of this complex separate from the temperate material, based on morphological differences and polymorphisms in DNA sequences.
