Basidia and pseudoparaphyses could not be observed due to deliquescence. Pleurocystidia not observed.

Elements of veil 45–200 × 5–30 µm, consisting of from C. littoralis by its more robust habit, smaller spores (9–12.5 cylindrical septate hyphae, rarely branched, densely packed, × 7–9 µm) and by fruiting on strongly nitrified sites (gardens, very variable in size and shape. roadsides and paths or on lawns). Coprinus sterquilinus differs Habit, Habitat & Distribution — Growing solitary on sand in from C. littoralis by its larger spores (17–26 × 10–15 µm) and littoral dunes with psammophilous vegetation.
