Bactrospora totonacae (Arthoniales, Ascomycota), a new species from Veracruz, Mexico
Background and Aims: Bactrospora is a genus of crustose lichens characterized by its black, verrucose to denticulate and little apothecia, and mostly acicular, or sometimes muriform spores, longer than wide. The genus is represented by 38 accepted species. The aim of this work is to describe Bactros...

| description | Background and Aims: Bactrospora is a genus of crustose lichens characterized by its black, verrucose to denticulate and little apothecia, and mostly acicular, or sometimes muriform spores, longer than wide. The genus is represented by 38 accepted species. The aim of this work is to describe Bactrospora totonacae, a new species from the tropical dry forest of Veracruz, Mexico. Methods: The specimens were collected on the “Cerro de los Metates” in the municipality of Actopan, Veracruz, Mexico. Macrochemical tests, UV reaction, and a thin layer chromatography were performed; likewise, the presence of amyloid substances distributed in the thallus and ascomata was verified with Lugol’s solution. The voucher is deposited in the herbarium XALU of the Facultad de Biología of the Universidad Veracruzana. Key results: The new species Bactrospora totonacae is characterized by the pruine K+ reddish magenta in its disc. Conclusions: The described species is unique in Bactrospora because the combination of pruine K+ reddish magenta and a thick carbonized exciple has never been reported in this genus. |

Antecedentes y Objetivos: Bactrospora es un género de líquenes costrosos que se caracteriza por el color negro, aspecto verrucoso a denticulado y pequeño de sus apotecios, posee esporas mayoritariamente aciculares y en ocasiones muriformes, pero siempre más largas que anchas. El género está representado por 38 especies aceptadas. El objetivo de este trabajo es describir Bactrospora totonacae, una especie nueva del bosque tropical seco de Veracruz, México.Métodos: Los especímenes fueron recolectados en el “Cerro de los Metates”, municipio Actopan, Veracruz, México. Se realizaron pruebas macroquímicas, reacción UV y cromatografía en capa fina; asimismo, con la solución de Lugol se verificó la presencia de sustancias amiloides distribuidas en el talo y el ascoma. Las muestras estudiadas se depositaron en el herbario XALU de la Facultad de Biología de la Universidad Veracruzana.Resultados clave: La nueva especie Bactrospora totonacae se caracteriza por presentar pruina K + magenta rojizo en el disco. Conclusiones: La especie que se describe en Bactrospora es única porque la combinación de pruina K + magenta rojizo y un excípulo carbonizado y grueso no había sido reportada en alguna otra especie de este género.
