The yeast genus Saccharomycopsis Schiönning

In order to eliminate the confusion resulting from the homonymsSaccharomycopsis Schiönning andSaccharomycopsis Guilliermond and to eliminate the usage of the nameEndomycopsis which has been perpetuated contrary to the International Code of Botanical Nomenclature, the authors in this article outline the history of the speciesSaccharomycopsis capsularis Schiönning andSaccharomycopsis guttulata (Robin)Schiönning and give their reasons for proposing the nameCyniclomyces nom. nov. for the genus to which the second species is assigned, a step which permits the use of the generic nameSaccharomycopsis Schiönning to designate the genus currently cited asEndomycopsis. Um Unklarheiten, herrührend von den HomonymenSaccharomycopsis Schiönning undSaccharomycopsis Guilliermond, zu beseitigen und um den fortgesetzten Gebrauch der BezeichnungEndomycopsis, welche im Gegensatz zum Internationalen Code der botanischen Nomenklatur steht, auszuschliessen, haben die Autoren dieses Artikels die Geschichte der ArtenSaccharomycopsis capsularis Schiönning undSaccharomycopsis guttulata (Robin)Schiönning dargelegt und ihre Gründe dafür angegeben, den NamenCyniclomyces nom. nov. für die Gattung zu gebrauchen, zu dem die zweite Art zugeteilt wird. Dieser Schritt würde den Gebrauch des GattungsnamenSaccharomycopsis Schiönning für die Gattung, die gegenwärtig alsEndymycopsis zitiert wird, zulassen.

Six new Candida species from South African insect sources

Representatives of six new yeast species,Candida amylolenta, Candida entomaea, Candida insectamans, Candida insectorum, Candida nitrativorans andCandida silvicultrix have been recovered from material of various Bostrichid, Buprestid, Cerambycid, Platypid and Scoltyid infestations in indigenous trees in the Transvaal, Orange Free State, Natal and the Southern Cape Province. Descriptions of the new species are given. Vertreter von sechs neuen Hefearten,Candida amylolenta, Candida entomaea, Candida insectamans, Candida insectorum, Candida nitrativorans undCandidasilvicultrix, wurden von Material von verschiedenen Bostrichid, Buprestid, Cerambycid, Platypid und Scolytid Käfern, die einheimische Bäume in Transvaal, im Oranje Freistaat, in Natal und in der südlichen Kapprovinz, befallen, isoliert. Beschreibungen der neuen Arten werden gegeben.

Three new yeasts from South African insect sources.

Representatives of three new yeast species,Sterigmatomyces polyborus,Hansenula philodendra andTrichosporon melibiosaceum, have been recovered from insect infestations inFicus sycomorus, Cussonia umbellifera andAcacia karroo respectively. Descriptions of the new species are given.

Four new, relatedCandida species from South African insect sources

Representatives of four new yeast species,Candida hylophila, Candida dendronema, Candida silvanorum andCandida entomophila have been recovered from material of various Bostrichid, Cerambycid, Scolytid and Platypid beetle infestations in indigenous trees in the Transvaal, Natal and the Cape Province in South Africa. Descriptions of the new species are given and their relationship with previously described taxa is discussed.

Bullera dendrophila sp. n.

Two strains of an undescribedBullera species were recovered from frass of Buprestidiae larvae infesting a moribund specimen ofDichrostachys cinerea in the vicinity of Groblersdal in the Transvaal. A description of the new species,B. dendrophila is given.

Saccharomycopsis synnaedendra, a new yeast from South African insect sources

An undescribed, ascogenous, filamentous yeast species has been recovered from the ectosymbiontic fungal flora associated with xylomycetophagous Scolytoidea infesting indigenous trees along the North Coast of Natal and the South Coast of the Cape Province. A description of the new species is given. Ein bisher nicht beschriebene askogene, mycelbildende Hefeart wurde von der ectosymbiotischen Pilzflora in Gemeinschaft mit xylomycetophagen Scolytoidea isoliert. Diese Ambrosiakäfer fallen einheimische Bäume entlang der Nordkuste Natals und der Südkuste der Kapprovinz an. Die neue Art wurde beschrieben.

Five newTorulopsis species from South African insect sources

Representatives of five new yeast species,Torulopsis dendrica, Torulopsis philyla, Torulopsis silvatica, Torulopsis insectalens andTorulopsis nemodendra, have been recovered from material from Cerambycid, Platypid and Scolytid beetle infestation in indigenous trees in Natal and the Cape Province in South Africa.Descriptions of the new species are given and where possible, their most likely relationship with other species is indicated.
