Description

Teleomorphs are extremely rare in nature. It forms hemispherical to pillow-shaped stroma on wood, painted in yellow tones, with whitish flesh, with holes with peritheum . Askeys are cylindrical, 92-128 × 5.5-6.7 microns. Ascospores are warty, bicellular, then decompose into unequal cells.

Colonies on agar with 2% malt extract on the 4th day 3,5-6 cm in diameter. There is no pronounced smell. The reverse is unpigmented. Conidial sporulation in small velvety bluish-green cushions collected in concentric circles or concentrated around the edge of the colony.

On the 4th day of corn-dextrose agar, colonies with copious sporulation in pads in light green tones, without yellowish tones.

Conidiophores are incorrectly branched, ending with a branched sterile part of about 100 microns in length with twisting or hook-shaped branches. Phialides in whorls of 3–6, almost spherical to flaky, 3.3–5.6 × 2.8–3.5 μm. Conidia are pale green, oblong to ellipsoidal, 3-4.5 × 2.1-2.8 microns, smooth-walled. Chlamydospores are terminal and intercalary, sometimes bicellular.

Ecology and Importance

A widespread fungus found in soil and on various plant substrates, sometimes as a cocoa endophyte .

The teleomorph is known only from broad-leaved wood (possibly Sideroxylon ) on Reunion Island .
