Observation 10256: Lecidella euphorea (Flörke) Hertel
When: 2008-06-24
Herbarium specimen reported

Notes: crustose lichen, on juniper wood flake
THALLUS: gray, verruculose, thick, very dull, K-
APOTHECIA: black, lecideine, plane becoming v convex, rim prominant briefly when young becoming inconspic, matte-shiny, epruinose, large, epihymenium greenish-black, hymenium clear, hypothecium golden to reddish brown, exciple very thin and greenish to dark brown, all parts K-, all parts POL- or few tiny POL+ white crystals scattered throughout
SPORES: 8 per ascus, 1 cell, bluntly elliptical, clear, 11-13 × 6.2-7.0 µm (Q=1.8-1.9) (N=2), walls 0.7 µm thick

Would need to observe structure of ascus tip stained in IKI to be sure it is really Lecidella, but no Lecidea s. lato even comes close (Lecidea s. str. is strictly saxicolous).
