Mysterious spots on tunnel raspberries

An Extension agent found these spots on tunnel raspberries last week. The fruit has been sent to the clinic for identification. We have a couple of theories on what it may be, and will let you know what it is as soon as we receive confirmation.

  1. Hi,
    the results just came in from our clinic in Clemson. Cladosporium and Botrytis were found on stamen tissue on the fruit surface. This complex of plant tissue and fungus likely caused the discoloration. The Botrytis (causes gray mold) concerns me for obvious reasons.
