Three Hypomyces and one Cladobotryum species are studied and reported as new records and also new anamorph/teleomorph connections of fungicolous fungi for Iran. Anamorphs of two species H. aurantius and H. rosellus (Cladobotryum varium and C. dendroides, respectively) have already been reported from Iran. The anamorph/teleomorph association of H. polyporinus/C. clavisporum was also found and wa...

The production of invertases by anamorph (A. nidulans) and teleomorph (E. nidulans) was investigated. The best level of extracellular enzymatic production for anomorph was obtained in Khanna medium containing sucrose as carbon source, whereas for teleomorph the best production was archived using M5 medium containing inulin as carbon source. Despite this, rye flour was selected as carbon source....

Field surveys in Zagros forests located in western Iran were done to study some aspects of biology and host range of Biscogniauxia mediterranea during 2014-2016. The ability of its conidia and ascospores to cause the disease was evaluated under greenhouse condition. Ascospore viability and development of anamorph and teleomorph were surveyed under different conditions. The pathogen host range w...

We studied the possibility of a teleomorph associated with the genotypically diverse septoria speckled leaf blotch (SSLB) pathogen of barley, Septoria passerinii. A teleomorph in the genus Mycosphaerella had been predicted previously based on phylogenetic analyses. This prediction was tested with experiments in the Netherlands and the United States by co-inoculating isolates with opposite matin...

The ability of pathogenic fungi to switch between a multicellular hyphal and unicellular yeast growth form is a tightly regulated process known as dimorphic switching. Dimorphic switching requires the fungus to sense and respond to the host environment and is essential for pathogenicity. This review will focus on the role of dimorphism in fungi commonly called thermally dimorphic fungi, which s...

A comprehensive phylogenetic reassessment of the ascomycete genus Cosmospora (Hypocreales, Nectriaceae) is undertaken using fresh isolates and historical strains, sequences of two protein encoding genes, the second largest subunit of RNA polymerase II (rpb2), and a new phylogenetic marker, the larger subunit of ATP citrate lyase (acl1). The result is an extensive revision of taxonomic concepts,...

Fungi were isolated in pure cultures from decaying giant sequoias Geneva (Switzerland). Isolates genetically identified by ITS rDNA sequencing. Young sequoia trees artificially infected with a culture of Botryosphaeria parva. Henle-Koch’s Postulates demonstrated that parva was pathogenic to Sequoiadendron giganteum. When analysing the microorganisms associated canker and dieback symptoms (Sequo...

A Cordyceps species was found with a Beauveria anamorph state on larval insect cadavers on Obong mountains in Gangwon Provinces, Republic of Korea. Cultures from discharged ascospores formed an anamorph identifiable as Beauveria bassiana. This teleomorph-anamorph connection was also confirmed by the in vitro production of fertile ascomata from conidial cultures with morphology like that of fiel...
