    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.

    Notes: Abstract A 15 year-old girl and her 50-year-old mother from Jabalpur, India, were found to have phaeohyphomycotic skin lesions due toPhialophora richardsiae. Among the antimycotics testedin vitro, clotrimazole was found to be most active. Topical application of clotrimazole cream cured the lesions completely.

    Topics: Biology
    Notes: Abstract The anamorph life cycle of the black yeastExophiala (Wangiella) dermatitidis is described. The fungus is dimorphic, yeast cells being the prevalent form of propagation. The fungus is strongly hydrophilic, probably completing its anamorph life cycle in submersion. Adaptation to dry conditions is slow. Types of conidiogenesis comprise annellidic, phialidic and sympodial reproduction, in addition to isotropic development. Phialoconidia fail to germinate under the conditions tested, and thus may have a function other than dispersal. Sterile, multicellular bodies resembling aCapronia teleomorph are described.

    Topics: Biology
    Notes: Abstract Freeze-fracturing of outer wall layers ofCladosporium conidia revealed two types of ultrastructure, coinciding with taxonomic characteristics. The outer conidial layers were essentially smooth in the human pathogenic species,C. bantianum, C. carrionii, andC. trichoides. In contrast, mosaic arrays of rodlets on conidia were observed with freeze-fracturing in the saprobic species,C. cladosporioides, C. coralloides, C. herbarum, C. sphaerospermum, andC. variabile. Conidia ofC. elatum were an exception among the saprobic species as they had smooth surfaces. The present study supports the suggestion that the human pathogenicCladosporium species should be transferred to another genus.

    Keywords: black yeasts ; Dothideaceae ; Aureobasidium ; Kabatiella ; Hormonema ; Selenophoma ; dothiora ; Pringsheimia ; taxonomy ; PCR-ribotyping
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Taxonomic markers for differentiation of the anamorph genera Aureobasidium, Hormonema and Kabatiella were developed using PCR-ribotyping with the primers 5.8S-R and LR7 for amplification and the restriction enzymes Alul, DdeI, Hhal, MspI and RsaI for digestion. Aureobasidium and Hormonema are optimally differentiated with MspI; DdeI is particularly useful to distinguish aureobasidium, Kabatiella and Selenophoma. Relationships of the anamorph genera Aureobasidium, Hormoneng and Kabatiella with the teleomorph genera Pringsheimia and Dothiora are discussed.

    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Trimmatostroma abietis from the needles of conifers and from stone, mostly in Germany, is described. On the natural substrate it is characterized by stromatic conidiomata. Conidia are mostly two-celled, are arranged in long chains, and originate by intercalary dilatation of fertile hyphae. The wide morphological plasticity of the fungus and its physiological profile are described. Its occurrence as a saprophyte and possibly opportunistic pathogen on plants and as an invader of environments with low water activity, particularly stone surfaces, are discussed. Relationships with other taxa are outlined.

    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.

    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.

    Notes: Abstract The human-pathogenic fungus, Phialophora cyanescens sp. nov. is characterized by the abundant production of chlamydospore-like cell aggregates resembling the form-genus Phaeosclera Sigler et al., and by elongate phialides with ellipsoidal conidia. A brown pigment and a blue, acid-labile pigment may be present.
