Abstract Two new species in the genera Diploicia and Physcia are described from tropical dry forest of Mexico. Both supported by morphological, chemical molecular evidence. edulis , a heavily consumed invertebrates, is characterized lecanorine apothecia, dull brown epihymenium not diffused green pigment (K−), subhymenium conspicuously inspersed with oil droplets, diploicin chemosyndrome. We provide first evidence to support inclusion apothecia genus . ornamentalis previously reported under...
Abstract Species delimitation among closely related species is challenging because traditional phenotype‐based approaches, for example, using morphology, ecological, or chemical characteristics, may not coincide with natural groupings. With the advent of high‐throughput sequencing, it has become increasingly cost‐effective to acquire genome‐scale data which can resolve previously ambiguous boundaries. As availability increased, numerous analyses, such as BPP and SNAPP+Bayes factor (BFD*),...
Abstract Three species of Graphis ( Graphidaceae ) are described from Mexico two research stations the Universidad Nacional Autónoma de México (UNAM): Chamela Biological Station in Cuixmala-Chamela Biosphere Reserve, Jalisco, and Los Tuxtlas Tropical Veracruz. The new bungartzii Barcenas-Peña, Lücking, Herrera-Campos & R. Miranda is characterized by erumpent lirellae with a lateral thalline margin, striate labia laterally carbonized exciple, transversely septate ascospores, norstictic...
An inventory of foliicolous lichens in Mexican lowland and montane rainforest revealed a total 288 species, 238 which are new records for the country, raising number reported lichen species to c . 1800. Among records, there 29 recently described four Neotropics Americas, while five taxa first time Central America. The 293 now known from Mexico comprise nearly two-thirds pantropical cosmopolitan or intercontinentally distributed taxa, whereas little more than one-third Neotropical American,...
Twelve new lichenized species are described in Arthoniales and Ostropales from seasonally dry tropical forest Mexico: eight Graphidaceae, one Gomphillaceae, each Arthoniaceae, Roccellaceae, Opegraphaceae. The are: Acanthothecis alba Herrera-Camp., Barcenas-Peña & Lücking, differing A. poitaeoides the erumpent to prominent ascomata with partially exposed disc relatively broader ascospores; Bactrospora lecanorina Altamirano other patellarioides-type ascospores by zeorine ascomata, combination...
Abstract Background Mushrooms and lichens are natural therapeutic resources whose millenary importance persists in indigenous mestizo communities of Mexico. However, this regard, the northern part country there few ethnobiological explorations. This study investigates local knowledge medicinal mushrooms used by Yuman peoples, native speakers imminent danger extinction along with their biocultural heritage due to changes traditional primary activities usurpation ancestral lands. Methods...
Pyrenothrix mexicana Herrera-Campos, Huhndorf & Lücking spec. nova is described from leaves in the upper montane rainforest of Oaxaca State, Mexico. It second species genus Riddle, established at beginning twentieth century for single species, P. nigra a corticolous lichen restricted to southeastern United States. Both taxa have same thallus and perithecial morphology anatomy, but differs by its longer, transversally septate ascospores. The anatomy documented systematic affinities are...
In this study we present an analysis of the Pyrenula ochraceoflava group (Pyrenulaceae), focusing on Neotropics and based morphological, chemical, molecular data mtSSU, nuLSU ITS markers. We described three new species from tropical dry forests Mexico, confirm monophyly P. provide evidence for inclusion currently placed in genus Mazaediothecium within Pyrenula. aurantiacoretis sp. nov. is characterized by orange pigment covering thallus net-like fashion, muriform ascospores with 4 rows 1–4...
One new genus and two species of Graphidaceae are described from tropical dry forests Mexico, based on morphological molecular data the mtSSU, nuLSU ITS markers. The Jocatoa in subfamily Graphidoideae is to accommodate Graphis agminalis (syn.: Medusulina texana), previously known Colombia North America. resembles Diorygma but differs by having simple paraphyses tips that do not form an epithecium. similar monophorum larger ascospores, hypostictic stictic acids type paraphysis tips. In...
Five new species of foliicolous lichens are described from the montane forest in States Oaxaca and Puebla Mexico. All taxa belong to family Gomphillaceae (Ostropales): Gyalectidium nashii sp. nov., G. paolae rosae-emiliae Gyalideopsis applanata nov. (also known Costa Rica Guyana), Tricharia oaxacae In addition, pycnidia for Fellhanera naevia (Vain.) Lücking & Cáceres, diahyphae subalbostrigosa Lücking.

Bungartz F., Truong C., Herrera-Campos M. & Clerc P. 2018: The genus Usnea (Parmeliaceae, Lecanoromycetes) in the Galapagos Islands. – Herzogia 31: 571–629.As part of an ongoing, comprehensive inventory all lichens, is revised. In this represented by 27 species. Although 23 species had previously been reported, two are synonyms, and seven historic records must now be considered erroneous. Nine reported here for first time additional four described new to science: mayrhoferi, U. leana,...
Graphis robertusii Bárcenas-Peña, Herrera-Campos y Miranda es descrita por primera vez para la selva alta perennifolia de Los Tuxtlas,Veracruz. Es una especie conspicua caracterizada lirelas erumpentes con margen talino lateral, labios no estriados blancos pruinosos, excípulocompletamente carbonizado, himenio insperso, esporas transversalmente septadas ácidos estíctico, salazínico conestíctico como metabolitossecundarios. G. fue encontrada en corteza del dosel diversos sitios Reserva...
Abstract According to International Union for the Conservation of Nature (IUCN) guidelines, all species must be assessed against criteria during Red Listing process. For organismal groups that are diverse and understudied, assessors face considerable challenges in assembling evidence due difficulty applying definitions key terms used guidelines. Challenges also arise because uncertainty population sizes (Criteria A, C, D) distributions A2/3/4c, B). Lichens, which often small, difficult...
Abstract New collections are reported of the monospecific genus Polypyrenula , an apparently extinct and doubtfully lichenized fungus, typically classified in Pyrenulaceae . Anatomical studies reveal that it is facultatively lichenized. The structure its hamathecium suggests affinities with Dothideomycetes rather than Eurotiomycetes. Molecular analysis using nuLSU mtSSU markers demonstrates for first time inclusion Trypetheliaceae outside core genera as part early diverging lineages this...
