Gyalectidium setiferum Vězda & Sérus., a foliicolous lichen characterized by having some vertically oriented whitish translucent cilia surrounding a swollen greenish diahyphal mass, is reported as new to East Asia. It was collected from two localities on the lowlands of central Honshu in Japan where it grew on leaves of Aucuba japonica and Maesa japonica. The description with illustration based on the Japanese material is given. Gyalectidium setiferum has been included in this genus due to its morphological features even though no fertile specimen has been found so far. The monophyly of this species and its position in this genus were newly confirmed by the molecular phylogenetic analysis based on mtSSU and nrLSU. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
