New records and a new species of Canalisporium from aquatic habitats in Panama.

摘要

Canalisporium panamense, a new species of aquatic mitosporic fungus from wood submerged in freshwater habitats in Panama, is described and illustrated. The characteristic features of the new species are colonies with few conidia, conidiogenous cells integrated, and dematiaceous muriform conidia. The conidia of C. panamense are larger in size (50-70x46-60 micro m) and have more septa than other described species in the genus. C. caribense, C. elegans, C. kenyense, and C. pulchrum are reported for the first time from wood submerged in rivers in lowland forests of Panama. No Canalisporium species were found at high elevations..
