 Note: This species reminds one macroscopically of Boletellus emodensis, but the two species are distinguishable in the field by the differences in their morphological characters. B. obscurecoccineus has pink pileus and stipe, both with carmine fibrils and scurfy warts on the surface, as compared to those of Boletellus emodensis.
