A group of two subspecies, uncialis and biuncialis. Although they are distinct based on molecular data, they are kept at the level of subspecies due to their closeness. Also, the diagnostic features are very variable and none of them is absolutely reliable. Subsp. uncialis has tri- to tetrapolytomous branching, while subsp. biuncialis has (anisotomous-) dichotomous branching. The latter also has a powdery surface of the central cavity of podetia and usually contains squamatic acid (UV+ blue-white).
