A ring of pink conidiophores and conidia is formed around the margin of the scab. Inoculation tests showed the fungus unable to penetrate through sound cuticle though it readily made entrance through wounds. It has been occasionally reported on living twigs and leaves and as a common saprophyte has long been known. The first account of it in America was from New York ^^ in 1902 though it was described in 1899 as injuring pears in Germany.^^^ Mycogone Link

RFFMD9A1–Aspergillus fungus, computer artwork. This is a toxic fungus that causes diseases in humans. These include fungal ear, lung and skin infections (otomycosis and pulmonary aspergillosis, and mycotic keratitis). It also produces aflatoxin, one of the most powerful naturally occurring carcinogens. This can cause cancers and disorders of the lung, liver, spleen, stomach, colon and kidney.
