Bryophyte of the Month
Orthotrichum cupulatum var. riparium Huebener, 1833
The debatable variety Orthotrichum cupulatum var. riparium photographed on rocks by the river at Richmond, Yorkshire during the Spring meeting 2018
Note the slightly exserted capsules, in which this differs from the usual Orthotrichum cupulatum. Accepted as a distinct variety by many bryologists in Europe, it is regarded by Smith (2004) and others as '...most likely an environmental modification not worthy of any taxonomic status'. The jury is still out...
Each month we will be displaying here a new bryophyte image, and the images shown in previous months will be kept for viewing in the gallery. Submissions for this page are very welcome, and should be sent to the Web Master , preferably as a 600 pixel width JPEG. It would be very useful if some explanatory text could be sent to accompany the image.
