Summary: Features include minute, blackish, shiny cups on cankers on living branches and twigs of true fir, smooth to flaky external surface, and microscopic characters. This is not the same as Godronia abietina (Ellis & Ev.) Seaver or Godronia abietis (Naumov) Seaver.
Microscopic: spores 40-67 x 3.5-4.5 microns, filiform [thread-like], with many oil droplets, finally distinctly 5-8-septate; asci 8-spored, or rarely 4-spored, reaching 118-135 microns long and 9-14 microns wide; paraphyses filiform, slightly enlarged in upper part, "somewhat agglutinated but not forming an epithecium"
Notes: Grovesiella abieticola was found in OR (Seaver). There are collections from BC at the Pacific Forestry Centre.
