Stephanospora michoacanensis (Stephanosporaceae, Agaricales), a novel sequestrate truffle from North America

Abstract

Stephanospora michoacanensis is presented as a new species from North America. This angiocarpic species is recognized by its yellowcream peridial surface color, and broadly ellipsoid to subglobose, spiny or crested, inamyloid spores with a distinct, complete or nearly complete corona at its base. Stephanospora michoacanensis is similar to S. caroticolor, but S. caroticolor has a bright yellow to reddish yellow peridial surface, and larger spores. Stephanospora michoacanensis also resembles S. chilensis, but S. chilensis has a brownishochraceous to reddish orange peridial surface, spiny spores that lack crest-like features. Illustrations of macro-and microscopic features are presented.
