TL;DR: A study of the apothecial pigments does not support the distinction of Nesolechia and Phacopsis, and a key to all known species of Lichenodiplis and Minutoexcipula is given.
Abstract: DIEDERICH, P. 2003. New species and new records of American lichenicolous fungi. - Herzogia 16: 41-90. A total of 153 species of lichenicolous fungi are reported from America. Five species are described as new: Abrothallus pezizicola (on Cladonia peziziformis, USA), Lichenodiplis dendrographae (on Dendrographa, USA), Muellerella lecanactidis (on Lecanactis, USA), Stigmidium pseudopeltideae (on Peltigera, Europe and USA) and Tremella lethariae (on Letharia vulpina, Canada and USA). Six new combinations are proposed: Carbonea aggregantula (= Lecidea aggregantula), Lichenodiplis fallaciosa (= Laeviomyces fallaciosus), L. lecanoricola (= Laeviomyces lecanoricola), L. opegraphae (= Laeviomyces opegraphae), L. pertusariicola (= Spilomium pertusariicola, Laeviomyces pertusariicola) and Phacopsis fusca (= Phacopsis oxyspora var. fusca). The genus Laeviomyces is considered to be a synonym of Lichenodiplis, and a key to all known species of Lichenodiplis and Minutoexcipula is given. The genus Xenonectriella is regarded as monotypic, and all species except the type are provisionally kept in Pronectria. A study of the apothecial pigments does not support the distinction of Nesolechia and Phacopsis. The following 29 species are new for America: Abrothallus suecicus, Arthonia farinacea, Arthophacopsis parmeliarum, Carbonea supersparsa, Coniambigua phaeographidis, Diplolaeviopsis ranula, Endococcus nanellus, Epaphroconidia hawksworthii, Globosphaeria jamesii, Hobsoniopsis santessonii, Lichenopuccinia poeltii, Melaspilea canariensis, Minutoexcipula mariana, Perigrapha superveniens, Pezizella epithallina, Phacopsis cephalodioides, Polycoccum minutulum, Pseudoseptoria usneae, Rhymbocarpus cruciatus, Sphaerellothecium parmeliae, Stigmidium mycobilimbiae, Taeniolella delicata, T. phaeophysciae, T. serusiauxii, Tremella papuana, T. phaeophysciae, Unguiculariopsis lettauii, U. thallophila and Vouauxiella verrucosa. New for North America: Endococcus apiciicola, Lichenochora galligena, Lichenoconium cargillianum, Opegrapha melanospila and Tremella leptogii. New for Central America: Cystobasidium usneicola, Endococcus apiciicola, Intralichen christiansenii, Lichenodiplis lecanoricola, Lichenostigma cosmopolites, L. maureri, Opegrapha melanospila, Syzygospora bachmannii, Tremella leptogii and Tremella parmeliarum. New for South America: Buelliella minimula, B. trypethelii, Cystobasidium usneicola, Epicladonia sandstedei, Lichenopeltella heterodermiicola and Lichenosticta alcicornaria. New for the UK: Carbonea aggregantula. New for Australia: Opegrapha melanospila. Zusammenfassung: DIEDERICH, P. 2003. Neue Arten und neue Funde von amerikanischen lichenicolen Pilzen. - Herzogia 16: 41-90. Insgesamt werden 153 Arten von lichenicolen Pilzen aus Amerika gemeldet. Funf Arten werden neu beschrieben: Abrothallus pezizicola (auf Cladonia peziziformis, USA), Lichenodiplis dendrographae (auf Dendrographa, USA), Muellerella lecanactidis (auf Lecanactis, USA), Stigmidium pseudopeltideae (auf Peltigera, Europa und USA) und Tremella lethariae (auf Letharia vulpina, Kanada und USA). Sechs Neukombinationen werden vorgeschlagen: Carbonea aggregantula (= Lecidea aggregantula), Lichenodiplis fallaciosa (= Laeviomyces fallaciosus), L. lecanoricola (= Laeviomyces lecanoricola), L. opegraphae (= Laeviomyces opegraphae), L. pertusariicola (= Spilomium pertusariicola, Laeviomyces pertusariicola) und Phacopsis fusca (= Phacopsis oxyspora var. fusca). Die Gattung Laeviomyces wird als Synonym von Lichenodiplis betrachtet, und ein Schlussel fur alle Arten von Lichenodiplis und Minutoexcipula wird gegeben. Die Gattung Xenonectriella wird als monotypisch betrachtet, und alle Arten auser dem Typus werden provisorisch in Pronectria behalten. Die Apothezien-Pigmente sprechen nicht fur eine Trennung von Nesolechia und Phacopsis. Folgende 29 Arten sind neu fur Amerika: Abrothallus suecicus, Arthonia farinacea, Arthophacopsis parmeliarum, Carbonea supersparsa, Coniambigua phaeographidis, Diplolaeviopsis ranula, Endococcus nanellus, Epaphroconidia hawksworthii, Globosphaeria jamesii, Hobsoniopsis santessonii, Lichenopuccinia poeltii, Melaspilea canariensis, Minutoexcipula mariana, Perigrapha superveniens, Pezizella epithallina, Phacopsis cephalodioides, Polycoccum minutulum, Pseudoseptoria usneae, Rhymbocarpus cruciatus, Sphaerellothecium parmeliae, Stigmidium mycobilimbiae, Taeniolella delicata, T. phaeophysciae, T. serusiauxii, Tremella papuana, T. phaeophysciae, Unguiculariopsis lettauii, U. thallophila und Vouauxiella verrucosa. Neu fur Nordamerika: Endococcus apiciicola, Lichenochora galligena, Lichenoconium cargillianum, Opegrapha

TL;DR: A two-locus phylogenetic study of the order Arthoniales is presented here using the nuclear ribosomal large subunit (nucLSU) and the second largest subunit of RNA polymerase II (RPB2) to analyse the first large phylogeny of this fungal group.
Abstract: A two-locus phylogenetic study of the order Arthoniales is presented here using the nuclear ribosomal large subunit (nucLSU) and the second largest subunit of RNA polymerase II (RPB2). This analysis is the first large phylogeny of this fungal group and includes 476 sequences and 240 specimens representing 132 species sampled from 31 genera (in their traditional circumscription). In addition to the previously recognized families (Arthoniaceae, Chrysothricaceae and Roccellaceae), three additional family-level groups are recovered, one being poorly supported. Therefore, the new family Roccellographaceae is described and the family Opegraphaceae is reinstated. Morphological characters such as growth form, fruit body type, exciple, hypothecium and ascospores colour, ascospores septation pattern, and chemistry are found to be of limited use in delimiting families and genera, which indicates an unusual level of plasticity in the Arthoniales. This high level of homoplasy might indicate that the Arthoniales is an old group with taxa having evolved in parallel for very long times. The genera Arthonia, Arthothelium, Chiodecton, Hubbsia, Ingaderia, Lecanactis, Lecanographa, Llimonaea, Opegrapha, Roccellina, Schismatomma and Sclerophyton were found paraphyletic. In order to make these genera monophyletic, the new genera Dimidiographa, Fulvophyton, Paraingaderia, Paralecanographa, Paraschismatomma and Sparria are newly described and the genera Alyxoria, Dictyographa and Zwackhia reinstated. The new species Lecanactis borbonica and Paraingaderia placodioidea are described.

TL;DR: A second fascicle of 75 Canadian lichens has been issued by the National Herbarium of Canada (CANL), including three lichens new for North America and one new combination was made in the exsiccata.
Abstract: A second fascicle of 75 Canadian lichens has been issued by the National Herbarium of Canada (CANL). Thirty-seven complete sets were distrib- uted. Included in the series were three lichens new for North America: Catillaria biformigera (Leight.) P. James, Ionaspis melanocarpa (Kremp.) Arn. and Lecanora cfr. laxula H. Magn.; and two species new for Canada: Buellia dialyta (Nyl.) Tuck. and Opegrapha rufescens Pers. One new combination was made in the exsiccata: Lecanactis megaspora (Merr.) Brodo and one is made here: Cladina terrae-novae fo. cinerescens (Ahti) Brodo. The National Herbarium of Canada is continuing to issue sets of Canadian lichens with this second fascicle of Lichenes Canadenses Exsiccati. By so doing, it hopes to make the Canadian lichen flora better known to the scientific community at large, and to provide uniform and well identified lichen material for general study. Fascicle II contains 75 numbers (nos. 76-150) including 42 from British Columbia (mainly from the Queen Charlotte Islands), ten from Saskatchewan, five each from Manitoba, Ontario and Quebec; two from Nova Scotia and Newfoundland; and four from the Northwest Territories.
