Brunnipila on fern
Edvin Johannesen, 29-07-2022 17:00
Edvin JohannesenQuick question, if I may: Are there several species of Brunnipila which can occur on pteridophytes? I have one on dead stem of Athyrium distentifolium at 1100 m alt. Is there a good key to Brunnipila?

Re : Brunnipila on fern
Good is relative and substrate preferences in the genus not well explored.
