Weather: Grey cloud cover but no rain

I found this in the front yard at a house right beside Mclean Creek Park. The house is located right on the edge of a clear cut. The dominate overstory species in the area range from Douglas fir, Grand fir, and Western Redcedar to Alder and baby Douglas fir growing in the clear cut. Around the edge of the property the most dominate understory species where Red huckleberry, salal, swordfern and some invasive species of blackberry and closer to the road scotch broom.

I found this on the ground all around the house and through out most of the backyard. It formed dense mats that where so thick they where spongy.
