Lichenicolous fungus on Pertusaria
Lepista Zacarias, 16-04-2016 22:54
Dear all,
Does anyone know something about the lichenicolous fungus in the photos attached?
It grew on the apothecia of Pertusaria heterochroa, has an brownish ascomata formed by more or less radially disposed hyphae (conidiophores?) at the top of which the conidia is formed. Conidia brown, 1-septate with dimensions in the ranges 4.6 - 7.7 × 2.2 - 3.4 µm.
Thanks in advance,
zaca

Re : Lichenicolous fungus on Pertusaria
You should look at Minutoexcipula, more remotely Lichenodiplis.
