Five species of the Laboulbeniales, including two unrecorded species are reported from South Korea. They are as follows; Dioicomyces anthici Thaxter on Anthicus confucii Marseul, Laboulbenia melanaria Thaxter on Anisodacthius tricuspidatus Morawitz, L. philonthi Thaxter on Philonthus wuesthoffi Bernhauer, Peyritschiella japonicus Terada on Philonthus japonicus Sharp, and Scaphidiomyces baeocerae Thaxter on Scaphisoma unicolor Achard. Among these species, L. melanaria Thaxter, S. baeocerae Thaxter and the male thallus of D. anthici Thaxter are newly described from South Korea. L. Philonthi Thaxter and P. japonicus Terada are newly collected in some places where were unlike with the examined region ago.

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.

Estimation of Cell Concentration by Light Transmitter During the Culture of Methylotrophic Yeast Pichia pastoris

The multiple correlation coefficient between the values determined by dry weight and those determined by fluorometer was observed with r = 0.96 and the standard error of calibration was 0.034. Using the best calibration data, in order to reconfirm the reliability of the fluorometer results in comparison with those obtained by dry weight on the cell concentration, fedbatch cultures were carried out. The results obtained by fluorometer measurements were in good agreement with those obtained by dry weight. The on-line monitoring of cell concentration by the fermentor system linked to a computer equipped with fluorometer was successfully carried out.

Interesting Species of the Laboulbeniales from Upo Swamp

Eight species belonging to two genera of the Laboulbeniales, parasitic on the family Carabidae and Staphylinidae of the order Coleoptera, were collected from Upo natural swamp in 1996-2001. They are as follows; Laboulbenia anoplogenii parasitic on Platynus daimio, L. cristata on Paederus parallelus, L. egens on Tachys laetifica, L. flagellata on Platynus daimio, L. pedicellata on Bembidion morawitzi, L. philonthi on Philonthus wuesthoffi, L. stenolophi on Acupalpus inornatus and Philonthus longicornis, and Peyritschiella biformis on Philonthus micaticollis. Among these species, the genus Platynus as the host of L. anoplogenii and the genus Acupalpus as the host of L. stenolophi are new to science. Bembidion morawitzi as the host of Laboulbenia pedicellata and Philonthus micanticollis as the host of Peyritschiella biformis are new to Korea.

Notes on Species of the Laboulbeniales from Yunnan Province of China

Six species of the genus Laboulbenia were collected from some regions of Yunnan Province, China, in July, 1994. They are as follows; Laboulbenia acupapi Spegazzini was collected on Abacetus submetallicus (Nietner) and Stenolophus iridicolor Redtenbacher. The host of this fungus has been only found on genus Acupalpus in the world so far, but it was newly found on genus Abacetus and Stenolophus. Laboulbenia anoplogenii Thaxter subsp. abaceti Santamaria was collected on Abacetus submetallicus (Nietner). Laboulbenia elaphri Spegazzini was collected on Nebria ochotica Sahlberg, but the host of this fungus has been only found on genus Elaphrus in the world so far. It was newly collected on genus Nebria. Laboulnebia flagellata Peyritsch was collected on Harpalus platynotus Bates and Platynus sculptipes (Bates). Laboulbenia polyphaga Thaxter was collected on Harpalus bungii Chaudoir. Laboulbenia vulgaris Peyritsch was collected on Bembidion misellum Harold and Bembidon scopulium (Kirby).
