I did not realize that this moss comes down to near sea level in our area.
This is getting moved back to Homalothecium in 2013.
Weedy pleurocarp
Looks similar too and was growing with Kindbergia praelonga. K. praelonga looks smaller and feathery, instead of a tangled mass of stems.
This looks similiar to one I saw at Lefferts Pond yesterday: http://www.inaturalist.org/observations/197811
Heavy growth on the trunk of an old walnut tree.
Stem and branch leaves are very different, and the stem leaves are squarrose. The capsule is cylindrical, narrow below the mouth when dry, and about 2.5 mm long, not including the lid. The seta is papillose.
Plant is irregularly pinnately branched. I showed a sample from the same patch to Ken Kellman and he said it's K. praelonga because it's not as large and plumose as K. oregana.
The plants were growing in the shade with leaf litter, next to a trail and not far from a stream.
