Caution: Do NOT use iSpot to identify fungi to eat!
Some fungi are very poisonous so a mistaken ID could have serious consequences.
No interactions present.
Cannot be sure from the photo, but I think there is at least one fissural, as distinct from tuberculate, soralium visible. B. fuscescens has both types; B. subcana has tuberculate soralia only.
But I think I recall DNA evidence casting doubt on their being separate species in any case.
