Setomelanomma holmii was originally described from France, but has recently been identified in USA and Canada. The fungus causes sudden needle drop disease in spruce trees appearing as solitary black fruiting bodies with sparse setae on the needles.
In the lab, it is a slow-growing pale mouse-grey fungal colony with a compact center where often short fluffy mycelium are seen.
Setomelanomma holmii is classified in the Pleosporales, one of the largest orders in the Dothideomycetes. Dothideomycetes is the largest and most diverse class of ascomycete fungi. It comprises 11 orders 90 families, 1300 genera and over 19,000 known species.
