Entomogenous fungi of arboreal Coleoptera from Worcestershire, England, including the new species Harposporium bredonense

During entomological surveys in ancient woodland and orchards in the English county of Worcestershire, dead arboreal beetles were found exhibiting external evidence of primary colonisation by anamorphic fungi belonging to the Clavicipitales. One of these proved to be an undescribed species and a new taxon is proposed: Harposporium bredonense on the larva of a longhorn beetle, Leiopus nebulosus (Cerambycidae), with a Hirsutella synanamorph. Hirsutella guignardii on the adult histerid beetle, Paromalus flavicornis, is a new host record, as well as a new fungal record for the British Isles. In addition, Lecanicillium psalliotae and Paecilomyces farinosus were isolated from mummified ecloded pupae of the Noble Chafer, Aleurostictus nobilis (Scarabaeidae), which is recognised as a rare or endangered species in Britain.
