摘要

Heterocyphelium triseptatum is newly recorded from Asia. The species was previously known only from South America and Africa. It was collected from the bark of a broadleaf tree at 35 m elevation in the Tanintharyi Region of southern Myanmar. An unidentified substance was newly detected for this species by thin layer chromatography (TLC). This study demonstrates the phylogenetic position of H. triseptatum in the Lecanographaceae using Bayesian and RAxML analyses of mtSSU and nrLSU sequence data. The close relationship with H. leucampyx within the Heterocyphelium clade was confirmed.
