Sarcosoma globosum - an indicator of climate change?

Occurrence of a spring ascomycete, Sarcosoma globosum has increased in Finland during the last three decades. River banks and old spruce forests are its typical habitats. Some of its habitats are damaged or even destroyed, however, because of forestry and building of roads and houses. It is a care-demanding fungus on the Finnish Red List, according to the IUCN criteria, but its present status is being discussed.
