Attachment and Germination of Conidia
1992Aquatic hyphomycetes have been shown to be successful colonizers of leaf material in freshwater streams (Ingold 1956, 1966, 1975, 1984; Shearer and Webster 1985a,b; Webster 1981). The initial requirements for colonization of a fresh substratum are the formation and liberation of conidia by the parent colony; these reach a peak concomitant with leaf ...

Mycological Research, 1991
The asexual conidial apparatus of Polyporus varius is illustrated. Both clamped (dikaryotic) and unclamped (monokaryotic) mycelia produce aerial conidiophores with sparingly branched chains of dry, ovoid, unicellular conidia. Most conidia from the mycelium with clamp-connections germinate to give unclamped mycelia, but about 10% give mycelia with ...

Biolistic transformation of conidia of Botryotinia fuckeliana
Current Genetics, 1994Botryotinia fuckeliana, the causal agent of grey mould, was biolistically transformed to hygromycin B resistance using a plasmid (pOHT) containing a bacterial hygromycin phosphotransferase gene fused to regulatory sequences from Aspergillus nidulans. Multiple copies of the plasmid, precipitated onto tungsten particles, were delivered into the conidia ...

Biological destruction of conidia ofVerticillium biguttatum
European Journal of Plant Pathology, 1996Because biological control ofRhizoctonia solani in potato with conidial suspensions of the mycoparasiteVerticillium biguttatum was often less successful in sandy soils than in loamy soils, we examined soils of potato fields for the presence of organisms destructive to conidia ofV. biguttatum.

Scanning electron microscopy of Penicillium conidia
Antonie van Leeuwenhoek, 1982The morphology of conidia in 211 species and 12 varieties belonging to the genus Penicillium Link ex Gray have been studied and compared. According to surface ornamentation, conidia have been classified into six groups: A, smooth-walled (7% of the species); B, delicately roughened (13%); C, warty (28%); D, echinate 910%); E, striate with low irregular ...

Germination of conidia in Phoma betae
Transactions of the British Mycological Society, 1988Variations in conidial germination in vitro and the influence of spore washing, molarity of the growth medium, pH, temperature, age of culture and light on the germination of conidia in Phoma betae are described. The germ-tube arises internal to the wall of the spore which is ruptured during germination.

The nature of the secondary conidia of Sporothrix schenckii
Mycopathologia et Mycologia Applicata, 1970Observations of secondary conidium production in an African strain ofS. schenckii revealed that secondary conidia are produced (1) acropetally on short sterigmata, (2) sympodially on short conidial appendages, and/or (3) sympodially or acropetally on short sporogenous cells which arise directly from the primary conidium. The secondary conidia therefore

The role of the conidia of fungi in fox spots
Studies in Conservation, 1996AbstractThe rusty-red, irregularly shaped areas known as foxing or fox spots are prevalent on rag paper used in books from the sixteenth to the nineteenth century. Foxing may vary in size from just visible spots to large areas covering most of a page, and in some cases the stain migrates through successive pages. The present study investigated the role

Mycologia, 1994
The process of endospore cleavage (sporan? giospore formation) within what were originally bal? listosporic conidia was examined with light and elec? tron microscopy in two isolates of Basidiobolus ranarum. A pathogenic isolate was obtained from skin ulcers on a frog (Davis isolate) and a nonpathogenic isolate was obtained from toad feces (Toad isolate)
