Description: Original observation #274298 (Mushroom Observer)
Occurrence Remarks: Growing on calcareous rock and locally abundant. The microscopy of this lichen was one of the most difficult for me, because the hymenium was unusually formed by some brown ragged tissues, which became red under the addition of a drop of KOH. Very small number of spores was observed.
