Didymodon fallax?
I have moved on to this moss. I have no idea what it is.. All the leaf tips are shed. the leaves are 2mm X .5mm the cells are linear at the base to quadrate at the apex. the stems are about a centimeter tall and packed together. It has rotten wood attached to it. Notes on the packet say 12-26-80 WS Rice hummus N84 3100 Skamania co T7n rwe sw14 s 7. So I guess it was collected in Skamania county at 3,100 feet on hummus. But it clearly is attached to rotten wood.

Pappilose!
I let my slide sit out overnight and now I can clearly see that these are pappilose leaf cells.. Kewl.. mystery solved...

Codriophorus (Racomitrium) aciculare from the herbarium
I am in the slow process of identifying 33 year old bryophyte (moss) samples from the TESC herbarium. I did two Racomitriums today. Racomitrium is tricky and the experts disagree so I try not to spend too much time banging my head over them. Here are some pictures of Codriophurus aciculare .
This one tricked me because I do not recognize cells like this to be pappilose. I honed on on Racomitrium aciculare right away in my field guide but kept dimissing it due to lack of pappilose cells. I love the online key to Oregon Racomitrium, in it I learned that these cells are pappilose, just not in a way that I recognize.
