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.

Ultrastructure of conidium germination of Cochliobolus carbonus

Canadian Journal of Botany, 1974
Multiseptate conidia of Cochliobolus carbonus germinate in water by one or two polar germ tubes. The septa between cells within a conidium contain a central pore, which is plugged before germination but open during germination, so that all cells are interconnected. During germination, vacuoles enlarge, endoplasmic reticulum profiles increase in number,

Conidium Formation in Species of Aspergilli

Mycologia, 1945
1. In three species of Aspergillus (clavatus, fumigatus, and repens) the conidia are formed as uninucleate cells on uninucleate phialides.2. The conidium of A.

Autoinhibition of Conidium Germination in an Isolate ofBipolaris [PDF]

Mycologia, 1980
Investigations on an isolate of Bipolaris sp. demonstrate that this fungus displays autoinhibition of conidium germination. Filtrates from 3-7-da-old agitated liquid cultures permitted germination in less than 5% of the conidia tested. Addition of nutrients to 5-da filtrates failed to overcome inhibition completely. The inhibitory activity of filtrates

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.

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. A secondary wall forms inside the phialide apex.

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.

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.

Conidium Ontogeny in Pyricularia¹

Journal of Phytopathology, 1984
AbstractConidium ontogeny of twenty‐three isolates of Pyricularia (including international races, some nutritional, coloured mutants and isolates obtained from cultivated and wild species of Gramineae) was studied. Among them, sixteen isolates were found to be of typical blastic type of conidiogenesis characteristic of the genus Pyricularia.
