Abstract

GUEVARA-GUERRERO, Gonzalo; BAEZ-ALVARADO, Ivone; GOMEZ-REYES, Víctor M.  and  CASTELLANO, Michael A.. Stephanospora michoacanensis (Stephanosporaceae, Agaricales), a novel sequestrate truffle from North America. Rev. Mex. Mic [online]. 2015, vol.41, pp.73-77. ISSN 0187-3180.

Stephanospora michoacanensis is presented as a new species from North America. This angiocarpic species is recognized by its yellow-cream 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 brownish-ochraceous to reddish orange peridial surface, spiny spores that lack crest-like features. Illustrations of macro-and microscopic features are presented.

Keywords : truffles; hypogeous; carrot-red truffles; sequestrate; Lindtneria.
