Four strains of an ascogenous yeast were isolated from the guts of the woodlice species Armadillidium vulgare (Latreille). This yeast differed from all known yeasts by its inability to grow in culture without the presence of a metabolite produced by some common soil fungi such as Cladosporium cladosporioides, Aspergillus alliaceus, and Penicillium spp. Phylogenetic analysis based on 18S rDNA and 26S rDNA (domain D1/D2) sequences indicated that the yeast represents a new taxon in the genus Debaryomyces. The new species Debaryomyces mycophilus is thus proposed. It was, furthermore, shown that the fungal metabolite necessary for growth of D. mycophilus did not provide the yeast with carbon, nitrogen or vitamins. The active compound was partially purified and it was shown that it is a siderophore used by the yeast as a source of iron. The addition of ferrichrome or high concentrations of FeCl(3) to growth media replaced the obligate dependence on a fungal metabolite. Symbiosis among fungi, based on the availability and utilization of iron, is an aspect of mycology that has not previously been recognized. The addition of chelated iron to isolation media could lead to the discovery of many unknown yeasts and fungi.

A new genus Ballistosporomyces Nakase, Okada et Sugiyama in the Hyphomycetes is described for yeasts that reproduce by both nonballistosporous conidia and ballistospores, but not by budding yeast cells. Non-ballistosporous conidia are produced on a sterigma-like stalk which proliferates sympodially or percurrently. Strains in this genus have Q-10 as the major isoprenologue of ubiquinone, do not contain xylose in the cells, and show positive Diazonium blue B reaction. Two new species, Ballistosporomyces xanthus (type species) and B. ruher, are described in the genus. Ballistosporomyces xanthus has a G + C content of DNA of 62.1 mol% and forms yellow colonies, whereas B, ruher has a G + C content of DNA of 50.8 mol% and forms red colonies. Some properties of the new genus indicate a Ustilaginale affinity. Ontogenetic and chemotaxonomic comparisons are made between Ballistosporomyces and other supposedly related basidiomycetous yeast genera.In 1987, Nakase (26) reported the isolation of two strains of yeasts which produce both ballistospores and "sterigmatoconidia" (conidia developed on sterigmata, not forcibly discharged, and often observed in strains of Sterigmatomyces and Fellomyces), but not budding cells. These two yeasts represent two distinct species but they cannot be placed in any known genera. Therefore, a new anamorphic yeast genus, Ballistosporomyces Nakase, Okada et Sugiyama, in the Hyphomycetes, is proposed for these yeasts. Two new species, Ballistosporomyces xanthus Nakase, Okada et Sugiyama (type species) and B, ruher Nakase, Okada et Sugiyama are described in the genus.
