A new species of the genus coreomyces (laboulbeniales ascomycotina) collected from the island of java, indonesia.

One new species of the genus Coreomyces was collected on Micronecta sedula from the island of Java; C. javanicus sp. nov. is very similar to and apparently closely related to C. corixae. This species is characterized by a receptacle that is bent towards one side with cell I, nearly rounded. The length of cell I is equal to that of cell II and the perithecia are longitudinal, elliptical or cylindrical. Thalli consistently occurred on the margin of the left elytron of the hosts.

Notes on species belonging to the genus coreomyces (laboulbeniales) collected from java island, indonesia.

Four species of Laboulbeniales collected from Java Island, Indonesia between August and September in 2006 are described. These species, which belong to the genus Coreomyces and were found on the family Corixidae of the order Hemiptera, were as follows; Coreomycus corixae Thaxter, Coreomyces micronectae Thaxter and Coreomyces orientalis Thaxter, which were found on Micronecta sedula Horvath, and Coreomyces recurvatus Thaxter, which was found on Micronecta sedula Horvath and Xenocorixa sp. C. corixae Thaxter and C. orientalis Thaxter were originally found on Micronecta, whereas C. recurvatus Thaxter was originally found on Xenocorixa. All species described herein are new to Java Island. The specimens were deposited in the Biological Herbarium, Division of Science Education, College of Education, Chosun University.

Notes on three species of the genus euphoriomyces (laboulbeniales) from Korea.

Three species of the genus Euphoriomyces (Laboulbeniales) were found newly from Korea. E. agathidii (Maire) Tavales was collected from Agathidium sp. (Leiodidae, Coleoptera). The characteristic traits of this species are the distal portion of the primary axis composed of 5~11 superposed layers and bearing more or less the elongated appendages. E. cybocephali (Thaxter) Thaxter was collected from Pseudocolenis hilleri Reitter (Leiodidae, Coleoptera). The primary axis of this species composed of 5~9 superposed layers is simple, not branched and a single antheridium occurs on the apex of the secondary axis. E. sugiyamae Majewski was collected from Scaphisoma rufum Achard (Scaphidiidae, Coleoptera). This species is very unique in having the antheridia formed as coner cells with lateral necks.

Notes on two species of the laboulbeniales from tibet.

Two species of the Laboubeniales based on the Tibetan collections are described. They are new to the mycological flora of Tibet. Laboulbenia polyphaga found on several parts of Amara majuscula was characterized by having the outer appendages not ramified and simple. Peyritschiella protea obtained on the lower abdomen of Philonthus wuesthoffi, had two perithecia and two antheridia produced on the third layer of receptacle.

Notes on three species of the laboulbeniales newly collected in Korea (2005).

Three species of the Laboubeniales from Korea are described. They are new to the mycological flora of Korea. Corethromyces purpurascens on several parts of Ochthephilum densipenne, Laboulbenia barbara on the metasternum of Philonthus longicornis and L. compressa on the elytra of Harpalus tinctulus were found.
