hello rejsharp,
when you scanned the mushroom, what part did you scan ?
do you try the cap, the stem, the underside of the cap, and did one the place seems a better place (more distinct spectrum) ?
i will try as soon as i have my scio, it would be a good idea to test the inside (after cutting the cap or the stem), because it think a lot of things in a real forest can get glue on the cap.
regards,
philippe
