Atrophysma T. Sprib. gen. nov.

Index Fungorum number: MB 830090; Facesoffungi number: FoF 13339

A cyanolichen with minutely coralloid, finger-like lobes over a black hypothallus, similar to Placynthium but ascospores are simple, similar to Leciophysma but with dark blue-black pigments in the apothecium; asci lacking an amyloid apical tube.

Type: Atrophysma cyanomelanos T. Sprib. (below).

Etymology: The genus name comes from atra (black), a reference to its colour impression in the field, and –physma, thought to derive from the Greek verb physao, to blow up or distend, and the suffix –ma, indicating a completed action (Verdon 1992).
