Abstract

The original material of Sphinctrina tigillaris, collected in 1864, was relocated, re-examined, found to represent a species of Chaenothecopsis, and is transferred to that genus as C. tigillaris comb. nov. It occurred on a specimen of a polypore, now identified as Perenniporia meridionalis, on a beam in a Northamptonshire church, and does not appear to have been collected since. Perenniporia meridionalis is a predominantly central and southern European species which has not previously been recognized in the British Isles, although other English specimens have now been located in collections at Kew and referred to the related P. medulla-panis. The name Sphinctrina tigillaris had been overlooked since its original description in 1865, and is nomenclaturally distinct from Lichen tigillaris, the basionym of Cyphelium tigillare. Notes on five other calicioid fungi found on polypores, and a key to the six now known, are also included.
