What are these tiny, gilled mushrooms growing on the side of an old dead log?

As far as I know this sp. always grows on wood. They are 6-8"tall, attached gills, white spores. The caps are gray when younger.

The tallest mushroom is about five inches.

The mushrooms in this picture looks like one of the chantrelles. They are usually darker brown, and about 3" tall. Most often growing in moss.

These were growing in sandy soil under white pines. They're about 2" wide and half as thick and fairly hard.

These are hard, woody, and about a quarter of an inch tall. They grow on standing dead oak trees near the base.

Same sp. as the previous picture.

This is a cottonwood log covered with bright yellow spores. Check the next photo.

This pic shows the lower portion of a cottonwood log. The yellow spores come from this pore bearing fungus.

1/2 to 1" wide, on downed wood, probably willow, not fleshy, covered with pinkish-orange spores.

Same sp. as previous pic. The pinkish-orange spores which normally cover the surface of these have been washed off by rain.

These are near the base of a dead oak . Numerous honey mushrooms also present. These are 3" tall and flat across the top.

The mushrooms in this photo are about 10% of the group. They are growing on the ground, and are 5-6" tall.

This is the same species as the following picture.
