The upper surface is often densely granular-isidiate, apothecia can be either absent or abundant. Occurs on calcareous soil and walls and crumbling mortar. Few Irish records but probably under-recorded. Chemical reactions negative Intermediate morphs occur between Leptogium plicatile (larger lobes) and Leptogium schraderi (cylindrical lobes). |
