LICHENS OF THE TINTERN FORAY. By H. H. Knight, M.A. T H Erocks in the Tintern district were similar to those met with at the Spring Foray at Matlock last year. In both districts Carboniferous Limestone rocks occur, but instead of the Millstone Grit of Derbyshire we had Old Red Sandstone rocks. The Wye Valley at Tintern however is well wooded, and consequently calcareous lichens were less plentiful than in the exposed valleys of Dovedale and Millers Dale. The most interesting find was O$egra$ha $araxanthodes, a lichen of shady calcareous rocks.
Transactions British Mycological Society. Several of the lichens in'this list were found on sandstone walls; these compared favourably with the grit walls in the Matlock district. Tree lichens were more numerous than in Derbyshire, though only some of the common species were met with. The parasitic fungus Ticothecium rimosicolum Arn. was found growing on Rhizocarpon petraeum. In the Journal of Botany, May 1925,Dr Watson has described under the. name Clathroporina calcarea a lichen found at the foray last year in Dovedale and Millers Dale. A few lichens in this list (indicated by the letter G.) were found on the left bank of the River Wye in Gloucestershire. Placynthium nigrum S. F. Gray Collema cheileum Ach. C. granuliferum Nyl.
