None of the rows peaks in December in Pennsylvania. Records of Hedgehog mushrooms, King bolete, Lion's mane and other Hericium drop below the listing line after November. "Peak month" means the month with the most records for that row; "rising" and "tailing off" describe the record counts on either side of it, nothing about the plant or fungus itself.

Source and date

Counts are public records by calendar month, shown as a share of each row's busiest month. A record means someone reported the species that month; it says nothing about quantity, ripeness or safety. Records follow where and when people go out, so busy weekends and popular parks count more than remote ground.
