Ultrastructure of septa in Blastobotrys and Sporothrix

Abstract
Transmission electron micrographs of septa in Blastobotrys species invariably showed central micropores. Septa of species of Sporothrix, however, exhibited three types of pores: (a) micropores which were central if single, or scattered; (b) central simple pores with Woronin bodies; (c) dolopores. The results confirm the heterogeneity of the genus Sporothrix.
