| Source | 44pp, The British Lichen Society |

| Review (by Malcolm Storey) | Reprinted from Lichenologist 15(1): 1-44, single-sided printing, so alternate pages are blank. A useful guide, but now (2004) rather outdated by the discovery of as many species again. A useful review in British Wildlife (vol 15, No 3, Feb 2004, pp 192-199) gives an overview of more recent developments. |
| Examine |  Compound Microscope |
| Specimen Preparation | Microscope slides of spores/asci usually needed; staining with Melzer’s Iodine for asci. |
| Identification difficulty | Comparatively straightforward, if the lichen is identified. |
