capsici such as globose oogonia with paragynous antheridia, chlamydospore
, torulose hyphae and lemon shape of sporangia with long pedicels as described by Mchau and Coffey (1995).
koningiopsis hyphal tip, hooks and chlamydospores
adhere to the hyphae of F oxysporum ciceri causing hyphal depression.
The Fusarium identification key proposed by Booth (1977) describes several characteristics, such as colony aspect, microconida formation structure, chlamydospore
presence and characteristics, macro and microconidia presence and size.
After incubation, the lid of the petri plate was removed and the edge of the cover slip was observed under the microscope (10X and 40X objectives) for typical morphological features like yeast cells, hyphae, pseudohyphae, chlamydospores
or arthroconidia along with budding yeast cells for Trichosporon spp.
ramorum), sporangia and chlamydospores
, and were placed directly into the inoculation cages (see below).
This fungus colonizes the roots of both plant species and produces hyphae and chlamydospores
in the rhizoplane of tomato plants.
On the other hand a surprising result was obtained where 36 strains failed to produce germ-tube and out of these 2 were positive for chlamydospores
coupled with results of carbohydrate assimilation and chromogenic agar these were identified as C.
However some authors consider it to be polymorphic exhibiting several different morphological forms including budding yeast cells (blastospores, blastoconidia), pseudohyphae (elongatged yeast cells that appear as filamentous cell chains), true hyphae and chlamydospores
The topics include the influence of light on the biology of Trichoderma, asexual development from conidia to chlamydospores
, metabolomic approaches to studying their interaction with plants, marine-derived Trichoderma as a source of new bioactive metabolites, and Trichoderma as a human pathogen.
africana doesn't produce chlamydospores
, doesn't grow at 42[degrees] C, tests negative for L-proline aminopeptidase activity, and grows in rough colonies on bird seed agar, instead of smooth ones.
audouinii was flat and had a brown velvety surface, and microscopically it showed thick-walled chlamydospores
either ter-minal or intercalary (Fig.
This is because ectomycorrhizal inoculum can persist for a short time after a disturbance as chlamydospores
, sclerotia, on root tips of surviving trees, and, briefly, as hyphae emanating from dying or recently dead root tips.
