The basidiomycetous yeast Rhodotorula yarrowii comb. nov.

Sequence analysis of the D1/D2 domains of the large subunit rDNA of Cryptococcus yarrowii (CBS 7417) indicates that this species does not belong to the hymenomycetous fungi, but instead is of urediniomycetous affinity. Therefore, the name change Rhodotorula yarrowii comb. nov.

Antibiotic secondary metabolites of Dichotomomyces cejpii.

Nine fungal strains of Dichotomomyces cejpii were studied for their ability to produce antibiotic metabolites. It was found that they produced secondary exo- and endometabolites with antimicrobial activity against Gram-negative and Gram-positive bacteria, yeasts and moulds and with a toxic effect against animal organs in vitro. Detailed chemical characterization of these active principles need to be carried out.

Four new species in Lipomyces.

For new species in Lipomyces are described. In terms of nuclear genome comparison the genus Lipomyces comprises three species-clusters. A key to the nine species now assigned to the genus, is given.

Cystofilobasidiales, a new order of basidiomycetous yeasts.

The order Cystofilobasidiales is described for teleomorphic basidiomycetous yeasts with holobasidia and teliospores. Their septa have dolipores, but lack parenthesomes. D-Glucuronate, nitrate and nitrite are assimilated and myoinositol is usually assimilated.

Molecular taxonomy and GC/MS of metabolites of Scytalidium hyalinum and Nattrassia mangiferae (Hendersonula toruloidea).

ARDRA of ribosomal genes confirmed that the hyphomycete Scytalidium hyalinum is identical to the coelomycete Nattrassia mangiferae (Hendersonula toruloidea, with arthroconidial synanamorph Scytalidium dimidiatum). S. hyalinum may be just a melanin-less cultural mutant of S.
