Southern Illinois Morel Season
"Virgin morel hunter here… any pointers? I'm in Southern Illinois." Southern Illinois (roughly south of I-64, including the Shawnee Hills) is usually where the Illinois season begins. It often starts two to four weeks ahead of the Chicago area.
Southern Illinois timing by area
| Area | Typical window | Notes |
|---|---|---|
| Shawnee Hills / far south | late March to mid-April | South slopes first |
| Mississippi and Ohio river bottoms | early to late April | Bottoms warm later but hold moisture |
| Metro-East / I-64 corridor | early to late April | Overlaps with St. Louis-area timing |
These are typical ranges. "Its still a bit cool in this area" is a fair early-April read in many years.

Land and rules
Shawnee National Forest allows gathering mushrooms for personal use only, with no selling. On IDNR state parks and fish and wildlife areas, collection is allowed at many sites for personal use, not resale, during the site's open hours. It's not allowed in dedicated nature preserves. During spring turkey season, areas open to turkey hunting are closed to mushroom hunters until 1 p.m. Call the site ahead of time for local rules, and always get the landowner's permission on private land.
Beginner pointers
- Scan "10 to 20 feet away, not directly down," then slow down once you find one.
- Carry a mesh or paper bag, not plastic.
- Learn the cut-in-half test and get ID help from experts. This page makes no edibility claims.
