. The vegetative hyphae of neither strain
fragmented during growth. The aerial hyphae of both strain
NRRL 15337T and strain NRRL B-16106T fragmented intoshort chains of conidia. This was clearly observed in scan-
ning electron micrographs of 14-day growth of both strains
(Fig. 1 and 2). The vegetative mycelia were branched and
approximately 0.5 km in diameter; the spores were ovoid
and 0.45 to 0.55 by 1.0 to 1.1 km and had smooth surfaces.
