This rock looks to have some type of Orthotrichaceae with brown sporophytes left over from last season. There also appears to be some Dicranum sp. in the lower left of the photo. These are just my best guess given what I can make out from the photo.
For this photo I am not sure what type of moss is in the lower center of the photo. Would anyone like to hazard a guess? As for the large patch of lighter green moss, I would bet money that is a species of Thuidium.
Thanks for sending the photos Em!
