Enterographa brezhonega Sparrius & Aptroot
Thallus absent, lichenicolous, visible as small whitish (or pale white-pink) mounds, pruinose, 0.2-0.5 mm diam., formed from several apothecia twisted together (= pseudostromata). Apothecia lirelliform, sometimes branched, 0.1 x 0.1 mm, clustured from 1 to 5, immersed within pseudostromata, disc shiny, not pruinose, orange-brown, dark brown, purple-brown to black, in general hardly visible. Asci 4-spored. Ascospores ellipsoid, straight to slightly curve, with perispose, 4-6-septate, with one of the middle cells sometimes enlarged, 15-20 x 2.5-3 µm. Photobiont: Trentepohlia. Pseudostromata : C-, K-, Pd-. Lichenicolous on Porina rosei ss. auct. brit. and possibly other Trentepohlia containing epiphytic lichens, on old oaks (Quercus) in old growth humid woodlands, here on Coenogonium luteum. N.B. potentially overlooked throughout the main host's range or confused with some Myxomycota. This species was found in the Coatloc'h woodland in Scaër, Brittany, and described based on these specimen, but present elsewhere in similar habitats on Coeogonium sp. in particular.
