Questions
When do people record mushrooms in Michigan?
In the public records, the busiest months are: Oyster mushrooms (May), Chicken of the woods (Sep), Morels (May), Lion's mane and other Hericium (Sep), Hen of the woods (maitake) (Sep), Chanterelles (Jul). That is when people reported them, not a forecast or a statement that anything is safe to eat.
When do people record wild fruit and nuts in Michigan?
Records of plants with fruit peak as follows: Sumacs (Jul), Elderberries (Aug), Blackberries, raspberries and relatives (Jul), Wild roses (hips) (Sep), Blueberries, huckleberries and relatives (Jul), Pawpaw (Aug). Fruit on a plant in a record says nothing about ripeness or edibility.
Is this a guide to what is safe to eat?
No. It lists when people recorded species in public datasets. It does not identify anything or judge edibility. Confirm every find with a qualified local expert.
