The Lobarion
The following provides some guidance on the identification of theLobarion lichen community.For fuller details see James, P.W., Hawksworth, D.L. & Rose, F.(1977). Lichen Communities in the British Isles pgs 322-327 in Lichen Ecology,Seaward, MRD (Ed.), Academic Press, London).
When well-developed this is a spectacular community that can include some of the largest foliose lichens.Unfortunately most of its constituent species are highly sensitive tosulphur dioxide, acid rain and excessive ammonia levels and many examples of theLobarion in Wales are now species poor.
The Lobarion is likely to be present on a tree or shrub or any rock facethat supports the following:-
Any species of the genera:
| Degelia | Menegazzia | Parmeliella (except P. parvula - see below) |
| Fuscopannaria | Nephroma | Pseudocyphellaria |
| Heterodermia | Pannaria | Sticta |
| Lobaria |
|
|
Any of the following species (* = species individually listed in Section 42):
| Agonimia octospora | Leptogium brebissonii* | Phyllopsora rosei |
| Collema fasciculare* | Leptogium cochleatum* | Porina coralloidea |
| Collema furfuraceum | Pachyphiale carneola | Porina hibernica* |
| Gyalecta flotowii* | Parmotrema crinitum | Punctelia reddenda |
| Gomphillus calycioides | Peltigera collina | Thelopsis rubella |

Any three of the following species:
| Acrocordia gemmata | Leptogium lichenoides | Opegrapha sorediifera |
