This issue of Mycological Research News features: Sudden Oak Death (Phytophthora ramorum) discovered on trees in Europe; and ‘Fusarium graminearum’comprises nine separate species. Eleven research papers appear in this part. Molecular studies reveal that the perithecioid Porinaceae are nested within ostropalean fungi; and that Gelasinospora species are nested with those of Neurospora, necessitating a broader concept of Neurospora. Also investigated are Armillaria species in the Czech Republic, and the status of Tricholoma bufonium. A new phytopathogenic Phytophthora is described with three subspecies causing diseases in Alnus; as are two new kickxcellalean fungi; and a new Streptopodium on papaya. Variation in and distributions of Duddingtonia flagrans and Eutypa leptoplaca genotypes are also reported.
