Role of the conidium in dimorphism of Blastomyces dermatitidis

Mycopathologia, 1978
Fine details of yeastlike cell development of Blastomyces dermatitidis from its conidium are described and illustrated by electron micrographs. When cultured in an enriched medium at 37C, conidia of two strains of B. dermatitidis readily underwent ultrastructural changes consistent with mycelial to yeast dimorphism.

Conidium liberation in Erysiphe graminis

Transactions of the British Mycological Society, 1971
The effects of various factors upon the liberation of conidia of Erysiphe graminis DC. f.sp. tritici Marschal (powdery mildew of wheat) were investigated, using a Hirst automatic volumetric spore trap and a range of meteorological instruments.

THE ERYSIPHE CICHORACEARUM CONIDIUM

Canadian Journal of Botany, 1967
The wall of the conidium of Erysiphe cichoracearum was composed of two layers. The inner layer was probably chitinous and possessed a few spines, whereas the outer layer was three or four times thicker and gelatinous. The end wall of the spore often was incompletely covered with this gelatinous layer. The cytoplasm of the dormant conidium had electron-

Conidium development in Ceratocystis autographa

Mycological Research, 1995
Ceratocystis s.l. includes Ceratocystis s.s., Ophiostoma and Ceratocystiopsis . These genera are distinguished by their anamorphs, ascospore morphology and sensitivity to cycloheximide. Ceratocystis autographa is unusual in that it reportedly has both Ophiostoma and Ceratocystis anamorphs.

Conidium ontogeny in Wallemia sebi

Transactions of the British Mycological Society, 1974
The ontogeny of conidia in Wallemia sebi, an osmophilic hyphomycete, has been studied, principally with the aid of slide cultures but also with the scanning electron microscope. A new technique for slide cultures is described which permitted examination of developing conidiophores at the highest obtainable optical magnification with excellent ...

Conidium Production in Penicillium

Mycologia, 1914
The fertile hyphae or conidiophores may arise as branches from submerged or from aerial hyphae. They are septate except when they are very short. They have approximately the same diameter as the vegetative hyphae from which they branch. They are uniform in diameter from point of origin to the point where the conidium-producing complex of cells begins ...

Phialide and conidium development in the Aspergilli

Transactions of the British Mycological Society, 1978
Observation of Aspergillus flavus Link, Aspergillus parasiticus Speare, and Aspergillus umbrosus Bainier & Sartory, using scanning electron and interference phase-contrast microscopy showed that a mixed colony of uniseriate and biseriate heads, as in A. flavus , was destined to become uniseriate and biseriate prior to phialide development.

Conidium wall structure in Seiridium and Monochaetia

Transactions of the British Mycological Society, 1980
Mature conidia of the Seiridium state of Lepteutypa cupressi and of Monochaetia monochaeta were examined by means of electron microscopy. Differences in wall structure, indicated by light microscopy, were confirmed, and are compared with Luttrell's distinction between euseptate and distoseptate conidia.

Autoregulation of Conidium Germination in Micromycetes of the genus Trichoderma

Microbiology, 2004
The amount of germinated conidia of micromycetes belonging to the genus Trichoderma considerably decreased with an increase in the population density. Strains exhibited different ecological strategies. The maximum number of germinated conidia (30–70%) was recorded when the average distance between conidia was 50 μm.

Conidium Ontogeny in Cacumisporium Capitulatum

Mycologia, 1969
Conidium ontogeny in the dematiaceous fungus, Cacumisporium capitulatum, was studied in culture. As the conidiophore matures, the heavy outer wall of the tapered conidiophore apex is broken and a hyaline meristematic area emerges. Conidia are produced from the hyaline meristematic region on successively produced growing points.
