Blue mold

 The rotted areas are soft, watery and light brown in color. The surface of older lesions may be covered by bluish-green spores that initially are nearly snow white in color. The lesions are of varying shades of brown, being lighter on the yellow or green varieties and on the pale cheeks of colored varieties and showing dark shades of brown on the most highly colored varieties. The soft, watery consistency of the rotted tissue seems to be a more distinguishing feature than the color variations.
