Summary

This work deals with some observations on Piedra in the Republic of Ecuador and it is a part of a general review about superficial mycoses which is now carried out in Guayaquil.

This study comprises the two varieties, black and white. Beside the description of the nodules, with its microscopic characteristics, the cultures are also described in both aspects: macroscopic and micromorphologic.

In black Piedra details of the asci are presented along with ascospores ofP. hortai (Brumpt)Fonseca &Leao, 1928. The A. found certain resemblance between the ascospores described and those ofP. javanica Boedijn &Verbunt, 1938. Typical black colonies were obtained beside otherTrichosporon type about which some interpretations are made.

In white Piedra its rarity is mentioned. The isolated organism is identified withT. giganteum Behrend, 1890 and its microscopic and cultural characteristics are described.
