Species plates
True Morel
Morchella spp.
Hollow honeycomb cap fused to a hollow stem. Pits are true pits (not wrinkles). The single most hunted spring mushroom in North America. Always cut in half lengthwise — true morels are hollow from tip to base.
Find: Hunt 10–18 °C soil after a warm rain. Natural morels hug dying elm, ash, apple, cottonwood and old-growth fir. Burn morels appear the spring after a wildfire, often at snowmelt line. Walk slowly and scan 1–3 m ahead; they camouflage as pinecones.
Pick: Pinch or cut at soil line. Do not yank the mycelium. Keep mesh bags so spores drop. Never wash in the woods. Split every specimen in the field and discard anything not fully hollow.
- True honeycomb pits, not wrinkles
- Completely hollow when sliced
- Cap fused to stem (not hanging)
- No reddish bruising or chambered pith
Lookalikes: False morel (Gyromitra); Verpa / half-free morel
King Bolete / Porcini
Boletus edulis complex
Fat brown bun cap over a swollen white stem with a fine net (reticulum) near the top. Underside is a sponge of pores, never gills. Pores start white, age yellow-olive. Flesh does not stain blue in true B. edulis.
Find: Mycorrhizal with spruce, fir, pine, and birch. Hunt after cool rains in late summer–fall. Look on forest edges, old roads, and mossy benches. Check every button for maggots by slicing the stem.
Pick: Cut high enough to leave the base. Slice immediately — if the sponge is green and the stem is tunneled, dry it or leave it. Never soak.
- Pores (sponge), never gills
- White netting on upper stem
- Flesh does not stain blue
- Young pores white, not red
Lookalikes: Bitter bolete (Tylopilus felleus); Blue-staining boletes
False Morel
Gyromitra esculenta
Wrinkled, brain-like reddish-brown cap, not a honeycomb. Stem is stuffed or chambered, not a single hollow. Spring fruiting in the same woods as true morels — the most important lookalike of the year.
Find: Same season as morels. Learn so you can walk past it.
Pick: Do not pick for the table. Photograph for ID practice.
- Wrinkled brain folds, not pits
- Stem stuffed or multi-chambered
- Red-brown, not gray/yellow honeycomb
Lookalikes: True morel
