Ecology: Biotroph; phytopathogenic; growing on stems and leaves, amphigenous. Host or Phorophyte Taxonomy: Galeopsis tetrahit L.; Galeopsis, Geraniaceae and Labiatae.

Reproduction Strategy: With sexual (and possible asexual) stages. Ascocarps: Cleistothecioid, orbicular, forming independently from the host thallus or mycelium, in loose groups and gregarious, (.085)-.1-.16-(.18) mm in diam.. Margin: External filaments present (often shorter than the cleistothecial diam.); interlaced with each other and interwoven with surrounding mycelium, mycelioid, straight, .25-2 µm long, 3.5-8 µm in diameter, hyaline and pigmented (brown), numerous, growing all across the lower half of the ascocarp (often forming a dense felt around the fruit-bodies), smooth, thin, not ramified and ramified (rarely), not branched, septate.

Asci: 5-16 asci per ascocarp, not stipitate and indistinctly stipitate, 40-80 µm long, 20-45 µm wide; dehiscence unitunicate (asci always immature in the current season, overwintered asci present).
