Description: Lichen. Thallus crustose, superficial, felty, white, ecorticate; hyphae irregularly branched, hyaline, mainly 1.5-2 µm diam., forming numerous convex to subglobose, pale cream sporodochia 0.4-1 mm diam., produced on white, elongate, straigh, simple or exceptionally bifurcate, hanging stipes with a rough surface, 0-1.5 mm long and 0.4-0.6 mm diam. Sporodochial conidia hyaline, smooth, 0-1-septate, with rounded or truncate apices, simple conidia (4.5-)5.5-7.5(-8.5) x (3-)3-4(-4.5) µm (n=50), 1-septate conidia (7-)8.5-12.5(-15) x (3-)3-4(-4.5) µm (n=60). Prothallus whitish, byssoid, 0,5-1 mm wide. Ascomata and pycnidia unknown (Ertz et al. 2011: 355).

Photobiont: Photobiont Trentepohlia.

Chemistry: Thallus and stipes of sporodochia C-, K-, KC-, P-, UV-. Sporodochia C+ red, K+ yellowish, KC+ red, P-, UV-. TLC: lecanoric acid, cf. roccellic acid and a colourless substance becoming pale olivaceous or brownish, UV+ green after heating (Ertz et al. 2011: 355).

Ecology: On underhang of volcanic rock.

Distribution type: Only known from the type locality.

Taxonomy: The species is easily distinguished from all other known Tylophoron species with Blarneya-type sporodochia by the stipitate sporodochia and the white, felty C- thallus.
