Apothecia: 0.5–2 mm in diameter, spherical to turbinate to discoid, sessile; hymenium yellow-orange to light orange, margin whitish, outer surface orange
Asci: 230-400(-480) x 21-30 µm, cylindrical, 8-spored
Paraphyses: slender, straight, mostly simple, rarely forked, pluriseptate, apical cell not or only slightly inflated, apical cell 35-80 x 4-7 µm, cells below 3 µm, containing orange pigment
Ascospores: globose, 18–22 µm in diameter, hyaline, with a spherical drop of 10–13 µm, uniseriate, ornamentation areolate, consisting of ridges (0.5–)0.7–1.2 µm wide and 0.8–1.5(–2) µm high, forming a complete regular reticulum of (3–)4–6(–7) pentagonal or hexagonal meshes/diameter, meshes 3–5(–6.5) µm wide, ridges and occasionally also ascospore surface between ridges dotted
Host: Campylopus pilifer
Infection; infects the rhizoids of the moss Campylopus pilifer, appressoria are usually covered by a layer of connate hyphae and only visible in optical section. They are slightly kidney shaped in side view 20–30 µm long, 12–18 µm high, 12–17 µm wide, and one-celled. Haustoria usually occur as one per appressorium, forming a ramified and contorted filament with undulating thin walls
Distribution: Canary Islands (Tenerife)
