Abstract

Two new species of Pyxine with yellow medulla from saxicolous habitats are described as new to science. The new species P. punensis has an isidiate, UV+ yellow thallus with 0·3–0·6 mm wide lobes. Pyxine yercaudensis has smaller ascospores (13–16×6–7 µm), lacks vegetative propagules and lacks lichexanthone.
