Oluna’s material belongs to the small-spore form of this species that has been described as Coprinus heptemerus f. parvisporus J. Breitenb. & F. Kränzl., Fungi of Switzerland, 4 Agarics, 2nd part: Entolomataceae, Pluteaceae, Amanitaceae, Agaricaceae, Coprinaceae, Bolbitiaceae, Strophariaceae. (Lucerne) 4: 236 (1995). Never mind, before we publish this new combination, we would like to measure the spores of the type specimen of Coprinus heptemerus M. Lange & A.H. Sm.

Spore size here seems small for C. heptemerus.

The spore size in the 1953 Lange and Smith description Mycologia 45: 751, available on Cyberliber, gives spore size for C. heptemerus as 10.8-15 × 4.4-7.5 um.
