associated with the fruiting body, are smooth and ellipsoidal to oblong. Each basidiospore is approximately 6 to 7 μm long and appear to possess a germ pore. Coprinites was originally placed in the family Coprinaceae based on the visible structures, or macromorphology of the fruiting body and the microscopic features preserved in the amber specimen. The combination of characters present did not match any modern genus of the mushroom order Agaricales leading Poinar and Singer to erect the genus Coprinites. The lack of autodeliquescence along with the mushrooms morphology lead David Hibbett, Michael Donoghue and David Grimaldi to question the placement of Coprinites. They noted the characters of the genus are similar to those of genus Leucocoprinus mushrooms. They suggested that Coprinites could be treated as either a member of Coprinaceae or Agaricaceae, to which Leucocoprinus belongs. With a number of molecular studies a large portion of the genera formerly placed in Coprinaceae, including Coprinus, have been moved into Agaricaceae. Thus supporting the suggestion of Hibbet, Donoghue, and Grimaldi.
