2010-10-10 Burgenland, district Oberpullendorf (spruce monoculture forest, 780 m AMSL).Some Polytrichum species surely, but I don't think it is P. commune or P. formosum.See also this shot here as well as this one and this one.
Orthotrichum affine. The presence of this moss is an indicator of relatively good air quality.Jan. 26, 2013, Millcreek Canyon, approx. 5,920 ft., growing on a tall deciduous tree, mainly on the north side, at about six feet from the ground.With respect to the moss, capsules and peristome teeth are visible (has 8 teeth). The leaves of the gametophtye have a common spiral arrangement, and appear to be mostly erect and only arranged in only a few spirals, and have recurved margins with acute tips . Capsules are furrowed (that can be see in connection with at least one of the capsules depicted here) and emergent to shortly exserted. There are at least three species of lichens.
This moss formed mats on the trunk of an oak tree near Mariah Meadows Resort (in hills Near Cobb, Lake County, California, March 29th 2012). This photograph was taken at home later from a collected piece to show a young capsule with its calyptra and a mature capsule with its peristome. Image I12-0482.
