We describe the new genus Marcelaria Aptroot, Nelsen & Parnmen for the Laurera benguelensis group, a small lineage within Trypetheliaceae that is well-supported in molecular phylogenetic studies and features distinctive ascoma morphology. The genus is characterized by sessile, solitary to ag...

description We describe the new genus Marcelaria Aptroot, Nelsen & Parnmen for the Laurera benguelensis group, a small lineage within Trypetheliaceae that is well-supported in molecular phylogenetic studies and features distinctive ascoma morphology. The genus is characterized by sessile, solitary to aggregate ascoma warts with broad, flat ostiolar region and often a split between the inner ascoma wall and the surrounding tissue. Three species are accepted in this genus, all previously placed in Laurera sensu lato: the neotropical and African M. purpurina (Nyl.) Aptroot, Nelsen & Parnmen, with bright red ascomata; the East Asian M. benguelensis (Müll. Arg.) Aptroot, Nelsen & Parnmen, with (orange-yellow) perithecia and an orange pruinose thallus, as well as inspersed hamathecium; and the East Asian M. cumingii (Mont.) Aptroot, Nelsen & Parnmen, with (orange-yellow) perithecia with a broad ostiolar region and a smooth, non-pruinose thallus, also with inspersed hamathecium. All three species are illustrated and a taxonomic key is given. The pigment chemistry of the species was clarified using comparative TLC analysis.

Introducimos el nuevo género Marcelaria Aptroot, Nelsen & Parnmen, para el grupo de Laurera benguelensis, un linaje pequeño dentro de Trypetheliaceae que tiene buen soporte en estudios de filogenia molecular y una morfología distintiva de sus ascomata. El género se caracteriza por tener ascomata sésiles, solitarios a agregados, con la región ostiolar ancha y plana y frecuentemente una fisura entre la pared interior del ascoma y el tejido adyacente. Se aceptan tres especies en este género, las cuales previamente fueron incluidas en el género Laurera sensu lato: M. purpurina (Nyl.) Aptroot, Nelsen & Parnmen, una especie del Neotrópico y de África tropical con los ascomata rojo brillantes; M. benguelensis (Müll. Arg.) Aptroot, Nelsen & Parnmen, una especie de Asia Oriental con ascomata amarillo-anaranjados y el talo con pruina naranja y el himenio insperso; y M. cumingii (Mont.) Aptroot, Nelsen & Parnmen, otra especie de Asia Oriental con ascomata amarillo-anaranjados y himenio insperso pero el talo sin pruina. Todas las especies y sus tipos son ilustradas con imágenes y se agrega una clave taxonómica. La química de los pigmentos se clarificó usando análisis de TLC comparativa. Descrevemos o novo gênero Marcelaria Aptroot, Nelsen & Parnmen para o grupo Laurera benguelensis, uma pequena linhagem dentro de Trypetheliaceae que é bem apoiada em estudos filogenéticos moleculares e apresenta morfologia distinta do ascoma. O gênero é caracterizado por verrugas de ascoma sésseis, solitárias a agregadas, com região ostiolar ampla e plana e, com frequência, uma divisão entre a parede interna do ascoma e o tecido circundante. Três espécies são aceitas nesse gênero, todas previamente colocadas em Laurera sensu lato: a neotropical e africana M. purpurina (Nyl.) Aptroot, Nelsen & Parnmen, com ascomas vermelhos brilhantes; a asiática M. benguelensis (Müll. Arg. ) Aptroot, Nelsen & Parnmen, com peritécio (amarelo-alaranjado) e um talo pruinoso alaranjado, bem como hamateca inspersa; e a M. cumingii (Mont.) Aptroot, Nelsen & Parnmen, do leste asiático, com peritécio (amarelo-alaranjado) com uma ampla região ostiolar e um talo liso, não pruinoso, também com hamateca inspersa. Todas as três espécies são ilustradas e uma chave taxonômica é fornecida. A química do pigmento das espécies foi esclarecida por meio de análise comparativa de TLC.
