Comments
This strain is recommended by ATCC for use in the tests described in ASTM Standard Test Methods D4300-88, D4445-91, and D4783-89 where only the taxon is specified.
Morphology Colonies growing rapidly, 8.0-9.5 cm in diameter after 4 days; aerial mycelium slightly floccose, white to grayish quickly turning dark bluish green from pistachio green with age. Chlamydospores abundantly produced, branching irregularly with each branch terminating with a cluster of 3 to 6 closely appressed phialides. Conidia broadly ellipsoid to obovoid appearing smooth walled, dark green.
