Sclerococcum stigma (Dactylosporaceae) a new combination for Dactylospora
stigma, a forgotten lichenicolous fungus that grows on Porpidia macrocarpa. A new combination,

localities in the Alps (Swabia and Austrian Tyrol) and the Pyrenees (Catalonia). A detailed description
of the species is included, and it is compared with the related species of the genus.
