1. plants light green, very debsely packed together, leaves tubular, seemingly without midrib.... 2
2. Stems 1-9 cm tall leaves 4-8 mm long.... Leucobryum glacum
A close up of the cell structure of the leaves would be a nice addition :-)
ReplyDeleteI think you need to look at Figure 4 again, those leaves are only about 1 1/2 mm tall, not cm. I think you have the wrong species here - it is albidum, not glaucum.
