In this experiment visibly contaminated seeds were removed (otherwise the stored seeds become a proliferating mass of fungal hyphae).
Some hyphae bodies were found encrusted with a precipitate.
The fungus was generally distributed throughout the lock in the form of spores, sporangia and short hyphae.
The white zone, found in each of the samples, comprised fungal hyphae filaments forming loose woolly webs around crystals of the substrate.
In the case illustrated, hyphae have penetrated the epidermal layer of the cotyledon, the cells of which are highly deteriorated.
A transmission electron micrograph of a matured spore and scanning electron micrographs of substrate and aerial hyphae are shown.
Careful histological examination showed no evidence of spores or hyphae in these tissues.
