Resumen

Se ha realizado una revisión sistemática de las especies norteamericanas con similitudes morfológicas con Inocybe grammata basándose en materiales recolectados en el este y oeste de Norteamérica y Centroamérica. Se confirman ocho taxones en el grupo propuesto aquí como I. sect. Albodiscae sect. nov., cuyas especies se caracterizan a menudo por un pileus bicolor con un disco pálido distinto, el margen cubierto de fibrillas sedosas superficiales, un estipe completamente pruinoso con una base bulbosa marginada ligera o evidente, basidiosporas angulares a angulares-nodulosas con comparativamente pocos nódulos, y cistidios de paredes gruesas. Las especies de la sección se distinguen principalmente por el tamaño del basidioma, el color y la textura del pileus, la variación en la longitud de las basidiosporas y el número de nódulos, hasta cierto punto la localización geográfica y la asociación vegetal. La sección incluye la ampliamente distribuida I. grammata (= I. albodisca), que se asocia con coníferas y abedules en el este de Norteamérica; I. albodiscoides sp. nov. del noroeste del Pacífico, anteriormente incluida en I. grammata e I. albodisca; I. floridana del norte de Florida, notificada por primera vez en más de 75 años; I. acriolens, una especie aparentemente asociada a la cicuta y el pino en el sureste de Canadá y el noreste de EE.UU.; I. grammatoides, una especie asociada al álamo temblón en las regiones septentrionales de EE.UU. y el sureste de Canadá; I. velicopia sp. nov., una especie asociada al roble y al castaño ampliamente distribuida por el este de EE.UU. y Costa Rica; I. panamica sp. nov. de bosques de roble y roble-Oreomunnea (Juglandaceae) de Costa Rica y Panamá; e I. vestalis, una especie europea hermana del resto de la secta Albodiscae, pero que carece de las características de I. velicopia. Albodiscae pero que carece del pileus bicolor distintivo. Se infieren filogenias independientes de ITS+28S, rpb2 y rpb1. Se proporcionan descripciones taxonómicas, ilustraciones y/o notas de los taxones norteamericanos.

title = "A revision of the Inocybe grammata group in North America including four new taxa",

abstract = "A systematic revision of North American species with morphological similarities to Inocybe grammata was conducted based on materials collected in eastern and western North America and Central America. Eight taxa are confirmed in the group proposed here as I. sect. Albodiscae sect. nov., species of which are often characterized by a bicolorous pileus with a distinct pallid disc, the margin covered with superficial silky fibrils, entirely pruinose stipe with a slight or obvious marginate bulbous base, angular to angular-nodulose basidiospores with comparatively few nodules, and thick-walled cystidia. Species in the section are mainly distinguished by basidiome size, pileus color and texture, variation in basidiospore length and number of nodules, to some extent geographic location, and plant association. The section includes the widely distributed I. grammata (= I. albodisca), which associates with conifers and birch in eastern North America; I. albodiscoides sp. nov. from the Pacific Northwest, previously subsumed under I. grammata and I. albodisca; I. floridana from northern Florida, reported for the first time in more than 75 years; I. acriolens, an apparent associate of hemlock and pine in southeast Canada and the northeast U.S.; I. grammatoides, an aspen associate in northern regions of the U.S. and southeast Canada; I. velicopia sp. nov., a widely distributed associate of oak and chestnut in the eastern U.S. and Costa Rica; I. panamica sp. nov. from oak and oak-Oreomunnea (Juglandaceae) forests in Costa Rica and Panama; and I. vestalis, a European species sister to the rest of sect. Albodiscae but lacking the distinct bicolored pileus. Independent phylogenies of ITS+28S, rpb2, and rpb1 are inferred.

Albodiscae sect. nov., species of which are often characterized by a bicolorous pileus with a distinct pallid disc, the margin covered with superficial silky fibrils, entirely pruinose stipe with a slight or obvious marginate bulbous base, angular to angular-nodulose basidiospores with comparatively few nodules, and thick-walled cystidia.

Albodiscae but lacking the distinct bicolored pileus. Independent phylogenies of ITS+28S, rpb2, and rpb1 are inferred.
