Sobre la presencia de pseudopyrenidium tartaricola (eurotiomycetes, hongos liquenícolas) en los Pirineos

The presence of Pseudopyrenidium tartaricola is mentioned in the
Pyrenees, specifically in the province of Huesca (Spain). Ps. tartaricola is a lichenicolous fungus with
predominantly arctic-boreal distribution, which grows on different terricolous or muscicolous species
of Ochrolechia. The provided record is the first mention for Spanish mycoflora, and corresponds to the
southernmost European locality known for this fungus. This floristic note is complemented with
original iconography of the habit and ascòspores.
