Vouauxiella lichenicola (Linds.) Petr. & Syd.
Ascomycota, incertae sedis: pycnidia immersed in apothecia of Lecanora species, notably L. chlarotera, conidia grey-brown, smooth-walled (described as finely verrucose by Sutton (1980)), produced in chains. Widespread and locally frequent.
Refs: Hawksworth (1976), 58 (line illustration); Hawksworth (1981), 65; Hawksworth (1983), 28; Sutton (1980), 24, 25 (line illustration); Diederich in Nash et al. (2004) 714.
Vouauxiella verrucosa is a rarer species on the same hosts, differing in its coarsely verrucose conidia. Microscopic examination is required for identification of these species.

Cross section of upper part of pycnidium and spores (in water, examined with Nomarski DIC, which has taken out some of the brown colour of the spores), in apothecium of Lecanora chlarotera, on Ash (Fraxinus excelsior) twig, Daimh-sgeir, Jura, May 2011 (BLS meeting). Note that the ostiole is oriented to the left in the photograph.
