Myriosclerotinia borealis is a species of fungus in the family Sclerotiniaceae. It is a phytopathogen, meaning it causes disease in plants. The species is known to affect a variety of crops, including barley, wheat, and canola.

Taxonomy

The genus Myriosclerotinia belongs to the family Sclerotiniaceae, within the order Helotiales. The species borealis is one of several within this genus.

Description

Myriosclerotinia borealis is characterized by its production of sclerotia, which are hardened masses of fungal tissue that can survive in the soil for extended periods. The fungus also produces ascospores, which are the primary means of dispersal.
