Ocellularia turbinata Mangold

in A.Mangold, J.A.Elix & H.T.Lumbsch, Fl. Australia 57: 656 (2009)

T: Kroombit State Forest, Dawes Ra., 53 km E of Biloela, Qld, 24°25’S, 151°02’E, alt. 800 m, on bark in rainforest on gentle slope, 27 Aug. 1993, J.A.Elix 34749; holo: CANB; iso: B.

  Thallus endophloeodal to epiphloeodal, to c. 300 µm thick, pale greenish to yellowish grey, dull to glossy, smooth, verrucose to verruculose, sparingly rimose. Protocortex indistinct, discontinuous, to 20 µm thick. Algal layer ±well developed, continuous; calcium oxalate crystals sparse, ±large and clustered. Vegetative propagules not seen. Ascomata ±conspicuous in older stages, to c. 0.8 mm diam., ±rounded to irregular, apothecioid, solitary, ±strongly emergent, ±verrucose and depressed-urceolate to urceolate. Disc with the columella visible from above, mainly epruinose, grey, free to often fused with the thalline rim, conical and often raised above it. Pores formed by the thalline rim margin, small to somewhat gaping, to c. 0.6 mm diam., ±rounded, moderately thin, entire when immature, becoming split to eroded, then the apex of the proper exciple becoming visible from above as a brownish to dark grey line, otherwise concolorous with the thallus or brighter; thalline rim incurved to erect in older stages. Proper exciple fused, moderately thin, brownish internally to dark brown or carbonised marginally, non-amyloid. Hymenium to c. 130 µm thick, not inspersed, conglutinated; paraphyses thin, straight to ±bent, parallel to slightly interwoven, unbranched, with ±thickened tips; columellar structures well-developed, to 500 µm wide, often replacing most of the hymenium, entire or becoming complex, conical, usually in large part raised above the hymenium, carbonised, with or without a sparse covering of greyish granules. Epihymenium hyaline to brownish, with greyish or brownish granules. Asci 8-spored; tholus thick when mature. Ascospores transversely septate, oblong to ellipsoidal, with ±rounded ends, hyaline, amyloid, 15–25 × 5–8 µm, with 4–7 (–8) locules; locules initially ±rounded to angular, becoming subglobose to oblong or lentiform, with hemispherical end cells; septa thin to thick, regular; ascospore wall thick, occasionally indistinctly halonate; endospore thick. Condiomata emergent, with a dark pore area. Conidia bacilliform, to c. 7 × 1 µm.
CHEMISTRY: Thallus K+ yellowish → brown, C–, P+ orange; containing constictic acid (major), stictic acid (major), hypostictic acid (minor to trace), α-acetylhypoconstictic acid (trace), hyposalazinic acid (trace), cryptostictic acid (trace), α-acetylconstictic acid (trace).
  Occurs on bark in rainforest to 1130 m altitude in eastern Qld and north-eastern N.S.W.; also in Brazil (Bahia, 1875, Miss Wilson ex Herb. Willey 712, FH-TUCK).
