Divergent Aspergillus flavus corn population is composed of prolific conidium producers: Implications for saprophytic disease cycle

Mycologia
The ascomycete fungus Aspergillus flavus infects and contaminates corn, peanuts, cottonseed, and tree nuts with toxic and carcinogenic aflatoxins. Subdivision between soil and host plant populations suggests that certain A. flavus strains are specialized

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 development in Sporothrix anamorphs of Ophiostoma

Mycological Research, 1997
Hyalorhinocladiella and Sporothrix are two common mycelial anamorphs of Ophiostoma that are difficult to distinguish from each other. Sporothrix spp. differ visibly from Hyalorhinocladiella by the presence of denticles on the conidiogenous cells. Graphium and Sporothrix are often synanamorphs of the same Ophiostoma species and the aim of this study was

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.

The fine structure of the Fusarium culmorum conidium

Transactions of the British Mycological Society, 1966
The structure of the conidium of Fusarium culmorum has been studied by means of ultrathin sections and electron microscopy. The cell wall is at least a triple layered wall of low electron density and fibrous nature. The inner wall continues uninterrupted into the cross-walls which did not show any pores.

Conidium ontogeny in the Chalara state of Ceratocystis adiposa

Transactions of the British Mycological Society, 1977
The Chalara state of Ceratocystis adiposa (Butl.) C. Moreau forms two types of conidial chain, one of which is easily fragmented and composed of hyaline conidia, the other persistent and composed of hyaline or pigmented conidia. A sheath exists around the persistent chains.

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 ontogeny in Riessia semiophora

Canadian Journal of Botany, 1973
Riessa semiophora is an imperfect fungus with basidiomycetous affinities. In culture, the fungus produces two types of conidia: unicellular microconidia and the compound stauroconidia that typify the genus. Both types of conidia are dikaryotic and on germination give rise to a mycelium bearing clamp connections.

Ethylene not responsible for inhibition of conidium germination by soil volatiles [PDF]

Netherlands Journal of Plant Pathology, 1978
Volatile factors inhibiting the germination ofBotrytis cinerea andCochliobolus sativus conidia on membrane filters were emanated from six alkaline and two acid soils of different organic content and origin. Addition of lime or chitin increased the inhibitory action.

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.
