Sooty Mold
In India, a black, fluffy fungal growth was observed on the
auricles of older leaves on either side of the leaf sheath. The
fungus was identified as Microxyphiella hibiscifolia Bat.,
Nasc., & Cif. Elongate to linear pycnidia, black to dark olive
in color, attach superficially to epidermal cells. Although described
as a pathogen (Singh and Grover 1968),
sooty mold fungi generally colonize insect honeydew or plant exhudates
and are not considered to be plant pathogens.
