A Revision of the Names of Foliicolous Lichenized Fungi Published by Batista and Co-Workers Between 1960 and 1975

Abstract

AbstractBetween 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.
