Ocellularia neopertusariiformis Hale

Bull. Brit. Mus. (Nat. Hist.), Bot. 8: 315 (1981)

T: Sabaragamuwa, Sri Lanka, M.E.Hale 47145; holo: US.

  Thallus endophloeodal to epiphloeodal, to c. 100 µm thick, pale to medium greenish grey, dull to glossy, smooth, ±verrucose to verruculose, ±rimose; verrucae near ascomata often eroded exposing the white to pale pinkish medulla. True cortex ±discontinuous, to c. 20 µm thick, formed by irregular to periclinal hyphae, or the thallus with a discontinuous protocortex. Algal layer well developed, continuous; calcium oxalate crystals large, clustered. Vegetative propagules not seen. Ascomata ±conspicuous, to c. 2 mm diam., ±rounded to irregular, perithecioid or apothecioid, solitary to marginally fused, immersed to emergent, often ±irregular and verrucose, urceolate to subglobose, occasionally depressed. Disc not visible from above. Pores formed by the thalline rim margin, to c. 0.5 mm diam., ±rounded to irregular, moderately thin to thick, usually ±depressed, entire to ±split, often evanescent, the apex of the proper exciple becoming visible from above as a brown to dark grey line, otherwise concolorous with the thallus; thalline rim incurved. Proper exciple fused, of moderate thickness above, yellowish brown to brownish internally and at the base, dark brown to carbonised marginally and above, prosoplectenchymatous, often amyloid at the base. Hymenium to c. 300 µm thick, not inspersed, moderately conglutinated; paraphyses ±bent to distinctly curly towards the tips, parallel to slightly interwoven, unbranched, with slightly thickened tips; columellar structures absent. Epihymenium hyaline, lacking granules. Asci 4–8-spored; tholus initially rather thick, thin when mature. Ascospores transversely septate, oblong-fusiform, with acute or faintly appendiculate ends, hyaline to yellowish or becoming pale brownish, amyloid, 80–200 × 10–20 µm, with 24–40 locules; locules ±rounded to angular, oblong to lentiform, with hemispherical to conical end cells; septa thin, regular; ascospore wall thick, thickly halonate only at the ends; endospore thick. Pycnidia not seen.
CHEMISTRY: Thallus K–, C–, P–; containing hypoprotocetraric acid (major), 2-hydroxy-hypoprotocetraric acid (major), 4-O-demethylnotatic acid (trace), convirensic acid (trace).
  A common, corticolous species in lowland and montane rainforest in eastern Qld and N.S.W.; also in Sri Lanka.
