Knudsen, K. & H. Fox 2011: Acarospora benedarensis: a rare terricolous maritime lichen from Ireland, Scotland, and Wales. - Opuscula Philolichenum 9: 31-34. [RLL List # 223 / Rec.# 32899] Abstract: Acarospora benedarensis, a rare terricolous lichen endemic to Ireland, Scotland and Wales, is discussed. It is recognized as having a much higher hymenium than described in the protologue with correspondingly tall asci. It is probably not a member of the new genus Silobia but further study of its systematic position is needed. A lectotype is also designated.
