Cross-site reference

Lichen taxonomy

Every genus observed in the atlas, with its canonical color (the same dot you see in stone strata, chips, and biodiversity bars). Identification is genus-level by default; species-level guesses are listed where morphology was unambiguous.

Caloplaca

16 stones

Bright orange placodioid rosettes — Mediterranean calcareous-rock specialist.


Species guesses observed

  • Caloplaca aurantia
  • Caloplaca sp
  • Caloplaca sp. or Candelariella sp

Verrucaria

14 stones

Endolithic — lives inside the stone matrix; visible only as black perithecial dots on the surface.


Species guesses observed

  • Verrucaria nigrescens
  • Verrucaria sp

Aspicilia

12 stones

Pale grey-green crustose film — the background substrate of Jerusalem-limestone communities.


Species guesses observed

  • Aspicilia calcarea

Candelariella

7 stones

Egg-yolk-yellow granular crustose — pioneer on smooth carbonate.


Species guesses observed

  • Candelariella sp

Lecanora

4 stones

Cosmopolitan urban-tolerant; *L. muralis* common on man-made stone.


Species guesses observed

  • Lecanora muralis

Bryophyta

1 stones

Mosses (not lichen — bryophyte). Often signals moisture availability at stone base.


The community profile is consistent with Galun & Haluwani (1977), Lichens on tombstones in Jerusalem: the dominant trio of Caloplaca + Aspicilia + Verrucaria with sub-dominant Lecanora, Candelariella and occasional foliose Xanthoria. Genus-level identification from photographs is reliable for distinctive morphologies; species-level requires microscopy and chemical spot tests (K, C, KC, P, UV).
