Mycelial mattress of Rhizopus stained with LCB

Rhizopus forms long unbranched hyphae called sporangiophores that produce sporangia in an upright fashion once the somatic hyphae have spread considerably. The sporangia at the tips of these upright hyphae are bulbous structures. Branching structures, called rhizoids, anchor the fungus into the substrate, releasing digestive enzymes and absorbing nutrients for the fungus. The mycelial mat…

Soft rot of tomatoes

Tomatoes which were accidentally left out in the kitchen at room temperature for two days showed a cottony growth. On fixing the sample on a slide and observing under a foldscope, branching pattern of hyphae resembling that of Rhizopus stolonifer was observed        (ref. ipm.ifas.ufl.edu/pdfs/Postharvest_Disorders.pdf) R. stolonifer can cause soft rot on soft fruits. Ripe…
