i live just south of bc, and the mushrooms going off right now are lobsters and chantrells.........do a spore test.....

My brother-in-law saw that I was eating some wild mushrooms (ones that I had done MUCH research on!). He got me a wonderful guide:
__National Audubon Society Field Guide to North American Mushrooms__. It has excellent pictures and all the info about spore prints, etc.

This is what it says about "Zeller's Bolete"---

Description: Black to dark olive-brown, dry, wrinkled cap with large, irregular, yellowish pores and reddish to yellowish-tan stalk.

Cap: 2-4" (5-10 cm) wide; convex to flat with age; margin incurved when young; dry, very powdery, wrinkled to bumpy, becoming smoother; blackish to dark olive-brown, fading to brown, often with reddish margin. Flesh white to yellowish, sometimes bruising blue. Tubes: often deeply sunken with age; olive-yellow, bruising blue. Pores large, yellow, often bruising blue.

Spores: 12-15 X 4-5 u; elliptical, smooth. Spore print: OLIVE BROWN.

Edibility: Good Season: Sept. - Oct. in Pacific NW; November--March in California
Habitat: On ground, in coastal forests and under redwood.

Lookalikes: B. crysenteron has brownish cap that typically cracks in a quiltlike pattern.

Comments: This beautiful western bolete has a dark cap with a powdery bloom.

(For a spore print, I simply get some stiff white paper--but have used paper towel or white rag in a pinch. Put the mushroom head on top of the paper...spore-side down. Leave it for a few hours...or overnight. In the morning, you should have a good spore print.)
