on ground, gravelly prairie
On rock in south puget sound prairie. In burned areas, but not until after many years.
On large rock seasonally submerged in river.
Most common in the drier regions of California. Grows in dense cushions.
Schistidium has a reddish wash, tends to grow in loose cushions, and is especially common in areas of intermittent flowing water.
Racomitrium has strongly sinuose lateral walls of the laminal cells (G. leibergii and G. trichophylla can appear that way as well) and is most common in the more coastal humid regions of California.
Narrow leaves with recurved margins and long hair point that is almost as long as the blade. Capsules bend back into the cushion, the lid has a long beak, the calyptrae only covers the lid, and capsules are held erect when old and dry.
Growing in round cushions on boulders near the creek.
Granite boulder, alongside small lake in pine grove. Apparently ideal habitat for this species.
Identified by microscopic examination.
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.
Commonly called Black-Tufted Rock Moss. Referring to brighter green moss pictured directly below Red Roof Moss (the one with all the large sporophytes). Difficult to see in photo, but sample was almost black on the bottom and brighter green on the top and un-branched. As you can see in photo, was growing on a rocky, periodically-wet substrate.
