Species Profile
Stigmidium degelii is a species of lichenicolous (lichen-dwelling) fungus in the family Mycosphaerellaceae. It was described as a new species in 1993 by the Swedish lichenologist Rolf Santesson. The type specimen was collected in Hordaland, Norway, in 1932. The species epithet honours Gunnar Degelius, who was the author's "first teacher in lichenology".
Stigmidium degelii faces severe threats from air pollution and acid rain, which degrade the quality of its lichen host substrates. Climate change and habitat loss through deforestation and urbanization further reduce available suitable environments for this specialized lichenicolous fungus.
