Description:

"About 1/3"" across, under oak log. Long legs (some broken off). Very cool cryptic texture on back. Alas, it's pancake spatula is covered with dirt, but you can tell it is there! Thanks to Ken-ichi for providing a fabulously detailed description of his observation of this very weird species on the other side of the mountains three days ago: http://www.inaturalist.org/observations/1207572 ID as per https://www.flickr.com/photos/23660854@N07/5548809652/in/set-72157603944294012 and http://bugguide.net/node/view/368921/bgpage"
