sulphureus were found. Hypocrea citrina stromata occur on the ground spreading from trunks; their yellow pigment is not concentrated Selleckchem Luminespib around the ostioles. Conidiation in H. citrina is generally more regularly verticillium-like. The type specimen of Hypocrea
colliculosa (K) was examined and found to represent H. pulvinata, based on the shape and size of ascospores, verrucose hairs on the stroma surface and colour and KOH reaction of stromata. The host of H. colliculosa is apparently old Fomitopsis pinicola with a largely disintegrated tooth-like hymenium. The specimen was collected in Vermlandia, Sweden and named but not published find more by Fries. He sent the specimen to Berkeley. Cooke found it in Berkeley’s herbarium and described it.
