Very rare, it is found on bark, usually of Elder Sambucus nigra or on young Elm Ulmus spp. It is recorded on the Isles of Scilly, Lundy Island, South Devon, Ireland and Portugal. More recently (2001) it was reported as new to mainland Cornwall from six metalliferous mine sites, where it occurs on trees in patches of scrub as a twig epiphyte of Elder, Sallow Salix spp. and Common Gorse Ulex europaeus .
