Revision of the genus Restingomyces, including two new species from Mexico

Abstract

To document sequestrate fungal diversity in American tropical regions, we performed a series of field surveys in southeastern Mexico and discovered two new species in the phalloid genus Restingomyces (Trappeaceae, Phallales). Here, we describe them based on morphological and phylogenetic analyses of mitochondrial adenosine triphosphatase (ATPase) subunit 6 and nuc 28S rDNA. Restingomyces guzmanianus is characterized by the brownish peridium, yellowish brown gleba, and ellipsoid basidiospores, whereas R. yaaxtax is characterized by the white peridium, pale green gleba, and small ellipsoid basidiospores. Both species occur in medium-statured tropical dry forest. The original diagnosis of the genus Restingomyces is emended to include these novel species. Illustrations are provided.
