A macro and micromorphological study of selected Ganoderma curtisii
specimens collected in Mexico were done. Traditional taxonomic methods were used,
making dissections through a trajectory from the base to the border of the pileus. The
macromorphological variation according to the state of maturation, presence or
absence of shine and color of the pileus, and form, color and size of the stipe, was
described; some relationships were established with the microscopic structures:
spores, structure of the pilear surface and hyphal system. From the observed
relationships, the most relevant was the yellow to orange-yellow pileus without shine
related with the cuticle poor developed, with cells not well-formed, thin-walled or
absent, present in young adult, immature or intemperized specimens. In adult
specimens, the cuticle cells from pileus margin are hyaline, with a very visible lumen
and generally septate, different from the cuticle cells from basidiomata center, which
are yellow to yellow-brown and thick-walled.
