GUZMAN-DAVALOS, Laura; HERRERA, María de Jesús; CARDONA, Beatriz E.  y  SALDARRIAGA, Yamillé. Gymnopilus tuxtlensis (Basidiomycetes, Agaricales), a tropical species known from Mexico and South America. Act. Bot. Mex [online]. 2006, n.76, pp.67-75. ISSN 2448-7589.

Gymnopilus tuxtlensis was described on the basis of specimens from Los Tuxtlas region, Veracruz, Mexico. In this work, more than 20 specimens either recently collected or deposited in several herbaria were studied. These specimens document a wider distribution of the species in Mexico (Jalisco), and its first record from South America, based on collections from Colombia and Venezuela. This species grows in tropical regions and is very characteristic because of its small, mustard-yellow basidioma, with a strigose base, long and characteristic pleurocystidia and smaller cheilocystidia.
