from conidiogenous pegs. Conidia produced on the longer
conidiogenous cells, nearly ovoid, 2.0–4.0 × 2–2.5 µm,
mean ± SD = 2.27 ± 0.19 x 2.12 ± 0.16 µm, L/W=1.1:1,
similar to conidia obtained from old cultures. Swollen
hypha also present.
An unidentified red pigment is always associated with
ascostromatic structures and the asexual morph in artificial
culture. Patches of red pigment are accumulated inside the
ascostroma, visible when cut. The red pigment appears in
culture as both diffusible and water insoluble substances.
The soluble red pigment stains the medium soon after the
