In var. davallianum the spines of the spores are 2–2.5 µm. Distal laminal papillae are hollow or occasionally solid, ca. 2 per lumen, usually simple but in some specimens (e.g., Ontario, Bruce County, C. Williams 1200, CANM) mostly 2-fid and hollow (with a distinct saddle between the projections) and distinctly C-shaped in optical section.
