Abstract

Neuwirth, G., Aptroot, A. & Stocker-Wörgötter, E. 2016. Hemithecium salacinicum, a new species in the family Graphidaceae (lichenized Ascomycota: Ostropales) from northern Thailand. — Herzogia 29: 555–560.

Hemithecium salacinicum is described as new from the province of Chiang Mai in North Thailand. The distinguishing characters from other species are the thallus, containing the depsidone salazinic acid only, the excipulum with a distinct yellow to orange coloured inner part and the poorly striate labia. The densely muriform, hyaline ascospores with dimensions of 60-110 × 15-22 µm are 25–36/5–7-locular and show conspicious constrictions at transverse septa.
