Protolog type data: Typus: Bermuda, Hamilton Parish, Walsingham Nature Research, Tom Moore Trail, 32°20.7'N-6°42.75'W, on decorticated trunk of Juniperus bermudiana, 3 m alt., 2 November 2007, F. Berger & S. LaGreca (BM-holotypus; ABL, LI, hb. Berger 22353-isotypi).
Type locality: Bermuda, Hamilton Parish, Walsingham Nature Research, Tom Moore Trail, on decorticated trunk of Juniperus bermudiana, 3 m, 2 November 2007, F. Berger & S. LaGreca (BM - holotype; ABL, LI, Berger 22353 - isotypes).
Type locality coordinates: 32°20.7'N, 6°42.75'W.
Thallus: immersed in the upper layer of the wood, visible only as a superficial white patch with small yellow dots (Trentepohlia) on the bleached surface. In section it consists of a homoiomerous layer of only 20 µm, built up predominantly by algae with some short (3 x 2 µm) hyaline hyphae projecting occasionally from the upper surface. The outer side of this layeer is partly free, partly covered by a thin coat of the woody substratum (endoxylous). This causes the mottled appearance under the hand lens. Apothecia sessile, constricted below, to becoming nearly turbinate, round, 0.3-0.8 mm diam., c. 0.2 mm high; disc flat, covered by a farinaceous bright lemon pruina; margins pruinose (glossy black when abraded), often distinctly dentate. Excipulum dense, carbonized black, up to 150 µm thick closed below. Epihymenium covered by bright yellow crystals, remaining ochraceous in section when crystals have dissolved in KOH. Hymenium hyaline, not inspersed, 100-150 µm high, K/I+ blue. Subhymenium mottled brown. Paraphysoides repeatedly branched rahter knobby towards the tips, not anastomosing; apices not thickened, c. 2 µm wide. Asci cylindrical, 60-75 x 6-8 µm, tholus longer than wide, Bactrospora-type. Ascospores 8/ascus, overlapping, filiform, straight to only slightly curved, 9-15-septate, 45-55 x 1.5-25 µm, not fragmenting, ends rounded ['patellarioides' type (Egea & Torrente 1993)]. Pycnidia and conidia unknown (Berger & Aptroot 2008: 544).
Photobiont: Trentepohlia-like, forming branches filaments of broadly fusiform cells with rough walls, c. 11-18 x 7-9 µm.
