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.

Ultrastructure of conidium ontogeny of Pseudobasidiospora caroliniana

Transactions of the British Mycological Society, 1979
The conidia of Pseudobasidiospora caroliniana are formed eccentrically on the conidiogenous cell by holoblastic extension of the wall. The unequal development of the conidium base is related to the distribution of endoplasmic reticulum and the vesicles originating from it.

Basidiospore germination and conidium development in Dacrymycetales

Transactions of the British Mycological Society, 1983
Basidiospore germination and conidium development are described in Dacrymyces stillatus, Calocera viscosa, C. cornea, C. pallidospathulata and Ditiola peziziformis . With the exception of C. pallidospathulata , all show 100% germination on malt agar within a day. Basidiospores are unicellular when discharged, but septation occurs subsequently.

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.

PHIALIDE AND CONIDIUM DEVELOPMENT IN ASPERGILLUS CLAVATUS

American Journal of Botany, 1976
Phialide formation in Aspergillus clavatus begins with the formation of thin areas in the vesicle wall. These thin‐walled regions and adjacent cytoplasm then push out synchronously to produce the phialides. Mature phialides are broadly oval with an attenuated base and tapered apex.

Polykaryon Formation Using a Swollen Conidium of Trichoderma reesei

2004
The cellulolytic fungus, Trichoderma has oval and mononucleate conidia. When these conidia are incubated in a liquid medium, they begin to swell and their shape becomes spherical followed by an increase in inner space. In such swollen conidia, it is possible to produce a larger autopolyploid nucleus using a mitotic arrester compared with the case of ...

Surface structure of the conidium and conidiophore of Stemphylium botryosum

Canadian Journal of Microbiology, 1973
Observations with the scanning electron microscope reveal tuberculate prominences up to 0.75 to 1.0 μ high and 0.5 μ wide on the suface of the conidium. The prominences are 1.0 to 1.5 μ apart and in the mature conidia have flattened cap-like tops. The swollen tips of the conidiophores are finely warted.

Further electron microscope studies of the conidium of Alternaria brassicicola

Archiv f�r Mikrobiologie, 1969
The freeze-etching technique, aldehyde fixation and heavy metal shadowing of wall material were used in an electron microscope study of the maturing spores of Alternaria brassicicola (Schw.) Wiltshire. The walls are composed of fibres, probably of chitin. The plasmalemma has rectangular grooves in its outer surface and corresponding ridges on the inner

Dermatophytes: conidium-ontogeny and classification.

Acta microbiologica Academiae Scientiarum Hungaricae, 1975
The ontogeny of the conidia of representative Dermatophyte species has been examined by time-lapse microphotography. The results are summarized in five main conclusions. (i) the genera Microsporum, Trichophyton and Epidermophyton have holoblastic conidium-ontogeny; (ii) the investigated species exhibit polymeristematic development; (iii) delivery of ...
