Who: Nina Filippova (courlee)

Specimen available

Habitat: ombrotrophic bog, community of treed bog (pine – dwarf-shrubs – Sphagnum fuscum), related trees: probably Pinus sylivestris, Pinus sibirica (dwarf-shrubs, if cortinaria may form micorrhiza with them).
There are about 10 species of cortinaria usually inhabiting in treed bogs in the area (i will post them all). My identifications are prior, but i am willing to work deeply with their systematics. It would be interesting to contact with a specialist in this group, since i am preparing checklist of larger fungi of bog, and probably there may be some collaboration between taxonomical and ecological approaches).

Colors of specimens were described in field with oac (online color chart), but unfortunately it has not names (only indexes), and it is not generally used by mycologists, since that rough common names were added, but they hardly exact (other information about color from pictures).
