RECORDS OF SUFFOLK CLADONIAE (LICHENS) S . A . MANNING, F . L . S . SOME of the cup-lichens, "reindeer m o s s e s " , and certain other m e m b e r s of the liehen g e n u s Cladonia f o r m an element of the Suffolk flora which is of s o m e importance in s u c h places as dunes, heaths, and expanses of sandy shingle. Unfortunately these interesting and often attractive plants are neglected by m a n y naturalists and botanists and it would probably be useful to f u t u r e workers to record the presence of s o m e of them in the county before more of their habitats are rendered unsuitable or disappear completely. In the following list n a m e s are arranged alphabetically. Where a species is included in that work, its n u m b e r in the C e n s u s Catalogue (Watson, 1953) is given in parenthesis after its name. Records are referred to the vice-county divisions (East Suffolk, v.c. 25, and West Suffolk, v.c. 26), which are separated by the line 1° E . longitude. A n asterisk indicates that Watson did not list the species for that particular vice-county. U n l e s s otherwise indicated, speeimens s u p p o r t i n g each record are preserved in the herbarium of the author, w h o m a d e those gatherings which are not accredited to other collectors. s Cladonia
