Altitudinal range: from the mesomediterranean belt (potential vegetation: evergreen broad-leaved forests dominated by Quercus ilex) to the submediterranean/colline belt (potential vegetation: mixed deciduous forests dominated by Quercus and Carpinus)
Note: a probably non-lichenised species with singly arising ascomata (to 0.3 mm in diam.) immersed in the outer layers of the wood, with a well developed ascomatal fringe, a dimidiate olivaceous-black involucrellum consisting of host cells and intermingled hyphae, the ascomatal wall brownish, of densely interwoven hyphae, interascal filaments numerous, anastomosing and persistent, 8-spored fissitunicate asci, and 1-septate, olive-brown to red-brown ascospores (18-22 × 8.5-10.5 µm) with the upper cell larger and with a thin perispore; on wood of Olea; a rarely collected species in California and Southern Europe, including the base of the Western Alps (France).
