Laboulbeniales (Ascomycetes) of Finland and adjacent parts of the U.S.S.R.

Abstract

About 160 000 specimens of insects, belonging to 1 100 species, and a few millipedes, mostly from museum collections, were investigated with respect to the occurrence of ectoparasitic,laboulbeniaceous fungi in Finland and adjacent parts of the U.S.S.R. In all 166 species of insects (Coleoptera and Diptera) were found to be infested by 88 taxa of Laboulbeniales (81 species from Finland and 42 species from the U.S.S.R.), all are reported from the area for the first time. All the fungus taxa are illustrated and their distribution mapped. Twenty-four taxa are described as new for science : Cantharomyces aploderi n. sp ., Dichomycesfurcifer subsp. subarcticus n. subsp., Eucantharomyces fennoscandicus n. sp., Fanniomyces copromyzae n. sp., Hydrophilomyces arcuatus n. sp.,

Infection of Harmonia axyridis (Coleoptera: Coccinellidae) by Hesperomyces virescens (Ascomycetes: Laboulbeniales): Role of mating status and aggregation behavior

“…It is a member of the Laboulbeniales, minute ascomycete fungi that complete their entire life cycle on a single arthropod host (Huldén, 1983;Tavares, 1985). The species was Wrst noted in the western United States on Chilocorus bivulnerus Muls.…”

A new species of Laboulbenia and new records from Panama

“…Thalli of Laboulbeniales were removed with a fine needle from the host insects and placed in a polyvinyl alcohol mixture for preparing permanent slides (Kirschner and Chen 2008). For the identification of the Laboulbenia specimens collected in Panama, the first two parts of Thaxter's world monograph of the Laboulbeniales (1902Laboulbeniales ( , 1908, Spegazzini's monograph for Argentina (1917), monographs from Asian (Shen et al 2006;Sugiyama 1973) and European countries (Huldén 1983;Majewski 1994;Santamaria 1998) were consulted, as well as the species descriptions published after 1908. Measurements are given as mean value ± standard deviation and extreme values in brackets based on n measurements or, when few measurements without statistical treatment were done, only as extreme values without brackets.…”

Autophagomyces, Bordea, and a New Genus, Rossiomyces, (Laboulbeniales)

“…In Finland, Hulden (1983) found what he identifies as A. falcatus on Cryptophagus bimasculatus (Panzer), C. pilosus, and C. setulosus Sturm. I have not seen any of Hulden's material.…”
