as the anamorphic state - Helicosporium virescens.

Grown on bark of Abies balsamea from this location (grown in damp chamber)

This species produce rather distinctive greenish colonies on the substrate. Under the microscope one will notice helicoid (coiled in a spiral) conidia produced on small peg-like conidiogenous cells with denticles. The conidiophore is hair-like, unbranched, pigmented and measuring at least 500u in length.

The greenish coloration of the conidia in mass, and their production on long unbranched conidiophore make this species rather distinctive.
