Workflow
Log Finds with Habitat Descriptors
ongoing per visitFor each fruiting body record tree species, substrate, elevation band, and surrounding moss or fern indicators.
Track Moisture and Temperature Index
15 minutes per visitAssign simple moisture scores (dry, moist, saturated) after rain events to correlate with fruiting success.
Tools Used
- NotepadPrimary
Maintain structured habitat logs linking tree species, moisture scores, and fruiting dates at each waypoint.
- Date Difference CalculatorPrimary
Calculate days between rain events and fruiting observations to build personal flush trigger models.
- Image CompressorSupporting
Compress habitat panorama photos for waypoint identification without GPS coordinates.
- Time Duration CalculatorReference
Track elapsed time between first pin and peak flush at each mapped tree association.

Tree Association ReferenceTable
Common North American mushroom–tree partnerships.
| Mushroom | Tree Partner | Soil Preference |
|---|---|---|
| Chanterelle | Oak, beech | Moist acidic duff |
| Bolete | Pine, spruce | Sandy well-drained |
| Hen of the woods | Oak base | Hardwood roots |
| Morel | Ash, elm, apple | Disturbed alkaline edges |
Flush Probability IndexFormula
High flush probability when moisture score ≥ 7/10 AND soil temp within species range for ≥ 3 consecutive days.
Citizen Science EthicsStandard
Obscure coordinates for commercially valuable or endangered fungi — share habitat type, not exact GPS.
Photo Waypoints
Unique rock or tree bark photos locate spots better than GPS in closed canopy forest.
Tree Not Spot
Mark the tree base for mycorrhizal species — mushrooms move but roots persist.
Coordinate Privacy
Publishing exact morel coordinates leads to over-harvest — generalize public posts.
Safety Notes
- Never eat a wild mushroom unless you are 100% certain of its identification.
- Habitat mapping often leads off-trail — carry navigation aids and tell someone your plan.
