Candle-snuff fungus, Xylaria ( X. hypoxylon, I think). These are small, twisty, white-tipped black thingies growing from the roots of a dead birch. Each is about an inch high. Smoke-like wisps of spores waft from the tips if you brush them.
One of the Boletaceae, I'm guessing Pale Roughstem, Leccinum holopus. Edible, speaking species-wise? Probably, but not these particular mushrooms-- they're growing in a nature reserve, which means poisoned karma if you pick one.
