    Notes: Abstract Total patterns of water-soluble proteins of 35 strains (7 species) of Galactomyces and Dipodascus strains with their respective Geotrichum anamorphs are compared. Quantitative differences among a number of species are found with iso-electric focusing; bands that characterize species are selected. Qualitative differences are found between the teleomorph genera.

    Coenzyme Q systems in ascomycetous black yeasts (1989)
    Springer
    Antonie van Leeuwenhoek 56 (1989), S. 349-356 
    Details
    ISSN: 1572-9699
    Keywords: coenzyme Q ; ubiquinones ; black yeasts ; Exophiala ; Aureobasidium ; Hormonema ; yeast-like fungi ; ascomycetes ; taxonomy ; chemotaxonomy

    Topics: Biology
    Notes: Abstract 72 Strains belonging to 44 species of ascomycetous black yeasts were analyzed for their coenzyme Q systems. Prevalent were Q-10 and dihydrogenated Q-10 systems. Members of the Dothidealean suborder Dothideineae have Q-10 (H2), while those belonging to the suborder Pseudosphaeriineae mostly have Q-10. The anamorph genus Exophiala Carmichael and the teleomorph genus Capronia Sacc. seem to be heterogenous.

    Contributions to a revision of the genusTrichosporon (1992)
    Springer
    Antonie van Leeuwenhoek 61 (1992), S. 289-316 
    Details
    ISSN: 1572-9699
    Keywords: Trichosporon ; white piedra ; systemic mycosis ; taxonomy ; nDNA ; rRNA ; ubiquinone systems ; basidiomycetous yeasts
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The genusTrichosporon was revised using characters of morphology, ultrastructure, physiology, ubiquinone systems, mol% G+C of DNA, DNA/DNA reassociations and 26S ribosomal RNA partial sequences. A total of 101 strains was used, including all available type and authentic cultures of previously described taxa. Nineteen taxa could be distinguished, 15 of which having Q-9 coenzyme systems and 4 having Q-10. Sixteen previously described names were reduced to synonymy. One new species was described. The genus is characterized by the presence of arthroconidia. Few species possess further diagnostic morphological characters, such as the presence of appressoria, macroconidia or meristematic conidiation. The septa of two species were found to be non-perforate, while those of the remaining species contained dolipores at variable degrees of differentiation, with or without vesicular or tubular parenthesomes. All species were able to assimilate a large number of carbon compounds; visible CO2 production was absent. The genus was found to be fairly homogeneous on the basis of a phylogenetic analysis of partial 26S rRNA sequences, with the exception ofT. pullulans which proved to be unrelated. Most taxa were found to occupy well-defined ecological niches. Within the group of taxa isolated from humans, a distinction found be made between those involved in systemic mycoses and those which mainly caused public or non-public white piedras, respectively. One species was consistently associated with animals, while others came mainly from soil or water. One species was mesophilic and another psychrophilic.

    Karyology and hyphal characters as taxonomic criteria in Ascomycetous black yeasts and related fungi (1991)
    Springer
    Antonie van Leeuwenhoek 60 (1991), S. 35-42 
    Details
    ISSN: 1572-9699
    Keywords: black yeasts ; Aureobasidium ; Hormonema ; Hortaea ; Ramichloridium ; Zasmidium ; karyology ; taxonomy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Mycelial development of seventy-three strains of black yeasts and related fungi were studied, and numbers of nuclei per hyphal cell were counted. Two main patterns were apparent in expanding hyphae, viz. (1) uninucleate expanding hyphal cells, septum formation strictly following mitosis, and (2) multinucleate, branched, aseptate hyphal tips, septa being formed in a later stage, leading to oligo- or uninucleate mature cells. Characteristic genera in the two groups areExophiala andAureobasidium, respectively. InZasmidium and in someRamichloridium species all mycelial cells are oligonucleate. The character is indicative for relationships at the family level in black yeasts.

    Neotypification of the genusTrichosporon (1992)

    Notes: Abstract The currently accepted type species of the genusTrichosporon Behrend isT. beigelii. This species has formerly been regarded as identical toT. cutaneum. However, these fungi are now known to represent separate species with different ecology. The first species described inTrichosporon wasT. ovoides, an agent of human white piedra. A neotype strain is designated for this species, while a lectotype strain is indicated forT. cutaneum. The nameT. beigelii is considered as doubtful and consequently cannot be maintained.

    Evolution of black yeasts: possible adaptation to the human host (1993)
    Springer

    Keywords: black yeasts ; dimorphism ; ecology ; ecophysiology ; evolution ; halotolerance ; medical mycology ; melanin ; meristematic growth ; opportunistic fungi ; taxonomy

    Topics: Biology
    Notes: Abstract Ascomycetous black yeasts show adaptations to a wide array of environmental conditions. Dothideaceous black yeasts are mostly found on plant leaves, while among herpotrichiellaceous species there are numerous opportunists on humans. Factors which are of ecological significance include the presence of melanin and carotene, formation of thick cell walls and meristematic growth, presence of yeast-like phases, presence of additional forms of conidiogenesis, thermo- and osmotolerance, adhesion, hydrophobicity, production of extracellular polysaccharides, siderophores and acidic or alkaline secondary metabolites. The potential pathogenicity of a species is partly determined by its natural ecological niche. Dothideaceous black yeasts are osmotolerant rather than pathogenic. Herpotrichiellaceous black yeasts probably have low competitive ability and are found in rather special niches as secondary saprophytes, e.g., on bacterial mats, on other fungi or in poor environments. Some species possibly utilize animal vectors for dispersal.

    Phylogenetic relationships ofCryptococcus neoformans and some related basidiomycetous yeasts determined from partial large subunit rRNA sequences (1993)

    Keywords: Cryptococcus ; Trichosporon ; rRNA ; phylogeny ; taxonomy ; basidiomycetous yeasts

    Topics: Biology
    Notes: Abstract The genusCryptococcus was found to be heterogeneous on the basis of partial rRNA sequences. The human-pathogenic speciesC. neoformans, comprising 4 serotypes and havingFilobasidiella neoformans andF. bacillispora as teleomorphs, was found at a relatively large distance fromFilobasidium. Serotypes B and C had identical sequences, while in A and D they were different, with D closer to B and C than to A.Filobasidiella depauperata, which lacks a yeast-like anamorph, clustered withF. neoformans. The genusFilobasidium was clearly separated fromFilobasidiella and clustered withC. albidus, C. kuetzingii, C. gastricus, C. lupi, C. vishniaciae, C. bhutanensis, C. aerius, C. terreus andC. ater. The latter may represent the anamorph ofFilobasidium elegans. The organe to red species ofCryptococcus, as well asC. aquaticus andC. yarrowii, were found completely unrelated with these taxa,C. macerans being affiliated toCystofilobasidium capitatum. The genusTrichosporon was found relatively homogeneous; it includesC. humicola, C. curvatus and the filamentous speciesHyalodendron lignicola. Cryptococcus flavus andC. dimennae probably belong to the Tremellales, though distances between these species are large. The positions ofC. laurentii andC. luteolus remains to be determined.

    Nutritional physiology and selective isolation ofExophiala dermatitidis (1993)

    Keywords: Exophiala ; Wangiella ; black yeasts ; taxonomy ; physiology ; chromoblastomycosis ; cystic fibrosis

    Notes: Abstract The nutritional physiology of ten strains ofExophiala dermatitidis was investigated. The growth reactions to lactose, citrate, nitrate, nitrite, lysine, creatine and creatinine differ from those found in closely related black yeasts. In addition, it is the onlyExophiala species which is able to grow at 40° C. A selective medium containingmeso-erythritol as sole carbon source was evaluated. This medium is particularly useful for the isolaton of black yeasts from lungs of patients with cystic fibrosis as well as from the environment.
