Agaricus guachari, sp. Nov. (Agaricales), from Venezuela.

Abstract

[ES] Se propone y describe Agaricus guachari como especie nueva para la ciencia. Este hongo se encontró viviendo sobre excrementos de "guácharo" (Steatomis caripensis Humboldt), que es un ave nocturna que habita en cuevas y se alimenta de frotos de plantas tropicales en Suramérica. El hongo presenta basidiomas blancos en fresco, que al rozarlos o cortarlos pasan rápidamente a tomar un color rojizo. Este hábitat tan característico, unido al hecho de presentar velo universal bien desarrollado y reacción negativa frente al reactivo de Schaeffer, confiere a esta especie una identidad propia que la separa y diferencia de los otros táxones de Agaricus conocidos hasta ahora. Además de la descripción completa, se aporta una detallada iconografía con los datos más relevantes sobre sus características micro- y ultramicroscópicas.

[EN] Agaricus guachari is proposed and described as a new species. It was found growing on dung of a nocturnal bird called "guácharo" (Steatornis caripensis Humboldt), in a cave, showing white basidiomata, which reddenned quickly when cut or robbed. Tbe habitat, presence of a well-developed universal veil and negative Schaeffer's reaction distinguished this species from the rest of taxa included in this genus. Data, including iconography, micro-and ultramicroscopic features, are also added.
