Clavulinopsis subarctica (Pilát) Jülich 1985 is a rare fungus which is occasionally found among Sphagna in raised bogs. It’s one of the very few clavarioid fungi (along with Clavaria sphagnicola) that grow in the demanding conditions of this biogeocoenosis. Indeed, I was surprised to find a coral fungus in the middle of a wet, sparsely treed peatbog west of the Kinyamiskoye lake near Ugut, and I doubt I’d ever find out what it was without help from a true expert in wetland fungi, Nina Filippova (check out her amazing flickr album).
You can read about this species (as Ramariopsis subarctica) in a 2012 Czech Mycology article by Martina Vasutova. As far as I know, it’s been collected in Yugra on one occasion, but, just like Ascocoryne turficola, it’s so rarely found mostly because it grows in nearly inaccessible spots very few mushroom enthusiasts would visit voluntarily 🙂
