The Fall Transition Quiz

Late August is a shift change — chanterelles clocking out, hen and lion's mane clocking in. Every new arrival has a double. Can you tell the fall pairs apart?

A quiz score is not an eating license

This quiz is for educational purposes only. Never eat a wild mushroom based on an app result, a photo, or a quiz score. Verify every find with multiple expert sources — spore print, field guide, and an experienced mycologist — and when in doubt, don't eat it.

Fall Transition Quiz

Six pairs from the seasonal handoff — each question is one species clocking out or clocking in, next to its double.

Question 1: Which cluster at the oak base is Hen of the Woods (maitake)?

[IMAGE PENDING]

Cluster A

Hundreds of small, overlapping gray-brown spoon-shaped caps; white pore surface; dense ruffled cluster at an oak base

[IMAGE PENDING]

Cluster B

A few huge cream-tan fan-shaped caps, each hand-sized or bigger; large pores running down the stalk

Question 2: Which toothed mass on a wounded hardwood is Lion's Mane?

[IMAGE PENDING]

Mass A

Spined mass branching like white coral, spines hanging along the branches

[IMAGE PENDING]

Mass B

A single unbranched pom-pom of long spines, no branches, all one mass

Question 3: Both shelves are orange-brown and on wood. Which is safe-to-pick Chicken of the Woods?

[IMAGE PENDING]

Fungus A

Velvety brown rosette with a yellow rim, growing from a CONIFER base among needles

[IMAGE PENDING]

Fungus B

Sueded bright-orange shelves, yellow pore surface, growing from an OAK trunk

Question 4: Two brown clusters on the same dead log. Only a spore print separates them. Which prints WHITE?

[IMAGE PENDING]

Cluster A

Smaller scattered caps, smooth and moist; thin fragile ring; overnight print comes out RUSTY-BROWN

[IMAGE PENDING]

Cluster B

Dense honey-tan cluster, dark scales at cap center, thick cottony ring; overnight print comes out WHITE

Question 5: Which cluster goes in the basket as Oyster Mushrooms?

[IMAGE PENDING]

Cluster A

Shelf-like white-to-gray caps on a standing dead trunk, gills running onto a stubby off-center stem, faint anise smell

[IMAGE PENDING]

Cluster B

Bright orange caps in a dense cluster at a stump or from buried roots, sharp-edged orange gills, orange flesh throughout

Question 6: Late-season boletes are past their prime and harder to read. Which aging bolete is still a Porcini?

[IMAGE PENDING]

Bolete A

Pores gone olive-YELLOW with age; fine WHITE netting on the upper stem; taste test of a tiny cap piece (spit out): mild, nutty

[IMAGE PENDING]

Bolete B

Pores gone distinctly PINKISH with age; COARSE DARK netting down the whole stem; taste test: instantly, unbearably bitter

Fall Transition Pairs to Study

Hen of the Woods (Grifola frondosa)

  • Hundreds of small, overlapping gray-brown caps
  • White pore surface underneath
  • Ruffled cluster at the base of mature oaks
  • Same oak often refruits for years — worth marking

Berkeley's Polypore (Bondarzewia berkeleyi)

  • A few HUGE cream-tan fan-shaped caps
  • Large pores running down the stalk
  • Same oak bases, same weeks
  • Not dangerous — tough and bitter with age

Lion's Mane (Hericium erinaceus)

  • Single unbranched pom-pom of long spines
  • Wounds and dead limbs of standing hardwoods
  • No toxic lookalikes in North America
  • Still verify every find before it's food

Bear's Head Tooth (Hericium americanum)

  • Branches like white coral, spines along branches
  • Also a Hericium — also edible
  • Fall's rare low-stakes mix-up
  • Knowing WHICH species you found is the habit that matters

Oyster Mushroom (Pleurotus ostreatus)

  • Pale white-to-gray shelf-like caps ON dead wood
  • Gills run onto a stubby, off-center stem
  • Faint anise smell when fresh
  • Must be growing from wood, not soil

Jack-o'-Lantern (Omphalotus illudens)

  • Orange cap, sharp-edged orange gills, orange flesh
  • Dense clusters at stumps or from buried roots
  • Causes hours of severe GI illness
  • Also famously mistaken for chanterelles

Three more pairs from this quiz — porcini vs bitter bolete, chicken of the woods vs velvet-top, and honey mushroom vs Deadly Galerina — carry over from peak season and are covered in depth in the Late-Summer Lookalike Quiz.
