The genus Coppinsia (lichenized Ascomycetes, Agyriaceae) with the single species C. minutissima sp. nov. is described as new from the British Isles. This minute lichen occurs on soil and bryophytes in metal-rich habitats. It is characterized by a minute thallus, biatorine apothecia with an almost reduced but generally cupulate exciple, slightly branched and apically unthickened paraphyses, a Trapelia-type ascus, and non-septate, ovoid ascospores.

Twenty species of lichenicolous ascomycetes are recorded for the western Pyrenees. Capronia hypotrachynae Etayo & Diederich (on Hypotrachyna species, also known from the Canary Islands and from Papua New Guinea), Llimoniella pubescens Etayo & Diederich (on Lepraria species, also from Scotland and Papua New Guinea), Polycoccum microcarpum Diederich & Etayo (on Cladonia species, also from Scotland), Skyttea megalosporae Etayo & Diederich (on Megalospora tuberculosa), Sphaerellothecium cinerascens Etayo & Diederich (on Cladonia parasitica) and S. parmeliae Diederich & Etayo (on Parmelia s. str., also from Finland) are described as new.

Between 1960 and 1975, 212 names of foliicolous lichenized fungi (or believed to have such a biological status) were described or used by A. C. Batista and co-workers. A considerable number of the new names were not validly published but mentioned as nomina nuda in various papers, while a further 69 names exist only as herbarium names. A taxonomic revision demonstrates that 36 of the 38 validly described genera ( = 95%) and 56 of the 68 validly published species and varieties ( = 82%) are either synonyms of previously known taxa, or represent non-lichenized or lichenicolous fungi, or cannot be readily identified and remain nomina dubia. Most of the descriptions refer to pycnidia, particularly those of the Strigulaceae (5 genera, 8 species or varieties), the hyphophores of Gomphillaceae (6 genera, 10 species), and the genus Microtheliopsis (3 genera, 3 species), whereas campylidia of the Ectolechiaceae are under-represented. A further six, monotypic genera correspond to lichenicolous or non-lichenized fungi. The following validly described taxa remain as autonomous genera or species of foliicolous lichens: Amazonomyces Bat., a generic name taken up for two species previously placed in Stirtonia and Cryptothecia, with two new combinations: Amazonomyces sprucei (R. Sant.) Lücking, Sérus. & Thor comb. nov. [Bas.: Stirtonia sprucei R. Sant.; Syn.: Amazonomyces palmae Bat. & Cavalc], and Amazonomyces farkasiae (Lücking) Lücking, Sérus. & Thor comb. nov. [Bas.: Cryptothecia farkasiae Lücking]; Lyromma Bat. & H. Maia, a distinctive genus of the Dothideales, with two species described by Batista and co-workers, and one new combination: Lyromma palmae (Cavalc. & A. A. Silva) Lücking & Sérus. comb. nov. [Bas.: Anconomyces palmae Cavalc. & A. A. Silva]; Arthonia lecythidicola (Bat. & H. Maia) Lücking & Sérus. comb. nov. [Bas.: Ameropeltomyces lecythidicola Bat. & H. Maia]; Arthonia orbignyae (H. B. P. Upadhyay) Matzer [Bas.: Opegrapha orbignyae H. B. P. Upadhyay; Syn.: Arthonia opegraphina Lücking]; Asterothyrium aspidospermatis (Peres) Lücking & Sérus. comb, nov. [Bas.: Actinoteichus aspidospermatis Peres] and Asterothyrium pernambucense (Cavalc.) Lücking & Sérus. comb. nov. [Bas.: Actinoteichus pernambucensis Cavalc], two apomictic pycnidial forms of Asterothyrium, in addition to the reinstalled A. umbilicatum (Müll. Arg.) Müll. Arg.; Byssoloma guttiferae (Bat. & Peres) Lücking & Sérus. comb. nov. [Bas.: Crocicreomyces guttiferae Bat. & Peres; Syn.: Byssoloma aeruginascens Vězda]; Phyllobathelium leguminosae (Cavalc. & A. A. Silva) Lücking & Sérus. comb. nov. [Bas.: Septoriomyces leguminosae Cavalc. & A. A. Silva]; Tricharia couepiae (Bat.) Lücking & Sérus. comb. nov. [Bas.: Aderkomyces couepiae Bat.] and Trichothelium brasiliense J. L. Bezerra & L. Xavier. Echinoplaca amapensis Bat. & Poroca, a distinctive species with characters that suggest a placement into the Arthoniaceae, will most probably require a new genus when more material is available. One species is validated and two are described as new: Bapalmuia verrucosa Serus. & Lucking spec, nov., Enterographa batistae Lucking & Serus. spec, nov. and Opegrapha ducket Bat., J. L. Bezerra & Cavalc. ex Lucking & Serus.
