Abrothallus curreyi
≡*Conida curreyi (Linds.) Vouaux, Bull. Trimestr. Soc. Mycol. Fr. 30 (2): 163 (1914).
Holotype: New Zealand. Otago, Saddlehill Bush, parasitic on Parmelia perforata [=Parmotrema reticulatum] on trunks of trees, 5.x.1861, W.L. Lindsay – E [fide Hawksworth (1977b: 173) this specimen is also the holotype of the fungus Microthelia cargilliana Linds. (=Lichenoconium cargillianum (Linds.) D.Hawksw. (q.v.) that parasitises the apothecial discs of the host (Hawksworth 1977b: 172–173)].
Description : Lichenicolous, developing on upper surface or somewhat immersed in upper layers of host (Vouaux 1914a: 163) Apothecia minutely papillate, black, convex, immarginate, partly immersed, discoid to tuberculiform becoming irregularly stellate or radiate with age. Epithecium dark-brown, granular. Hymenium colourless, I+ blue. Hypothecium dark-brown, granular. Asci clavate, 30 × 15 μm. Ascospores simple, colourless to brown, broadly ellipsoidal or suboblong, straight or slightly curved, with a tendency to become 1-septate, 7.5–8.5 × 6–6.5 μm.
S: Otago (Dunedin) on thalli of host in forest. Known also from Mexico where it is a parasite on Ramalina yemensis (Vouaux 1914a; Hawksworth 1977b).
?Palaeotropical
Host : Parmotrema reticulatum.
Illustrations : Lindsay (1866c: pl. XXIX, figs 1–5).
