Bolbitius aleuriatus is a synonym according to researchers who have broadened the concept of Bolbitius reticulatus to include the non-veined, grayish Bolbitius aleuriatus. Thus the species name reticulatus seems a little inappropriate for collections (like the ones illustrated) that lack the veined cap surface. The oldest name should take precedence; Persoon named Agaricus reticulatus in 1798, while Fries did not name Agaricus aleuriatus until 1815.
