). A smooth membranous veil originating anteriorly extends beyond the spore body posteriorly, enveloping the entire spore. Sutural ridge prominent anteriorly but thinner posteriorly. Keel-like appendages situated along the sutural ridge join together at the posterior extremity. Sporoplasm deeply staining and binucleate. Spore valves thin and smooth. Polar capsules pyriform, subterminal, one on either side of sutural line. Polar filament with 3–4 coils, not clearly visible. Dimensions, based on 15 fixed spores, as ranges with means and ± SD in parentheses: spore length 9.6–19.2 (13.64 ± 3.67); spore width 10.2–22.4 (19.03 ± 3.64); spore thickness 14.0–20.0 (16.09 ± 1.92); spore veil 32.0–48.0 (40.43 ± 6.47); polar capsule length 6.4–8.0 (6.93 ± 0.64); polar capsule width 3.2–5.4 (4.0 ± 0.80); spore length: spore width = 1: 0.8–0.96; polar capsule length: spore length = 1: 1.5–2.4.
