Didymodon insulanus fruiting

I found another rare fruiter, D. insulanus, with young sporophytes on the Taff riverbank last week. It was growing on a small area of red sandstone below Llandaff Weir with D. luridus, D. sinuosus, Barbula unguiculata and Bryum dichotomum.

It looks spot on for insulanus microscopically but if anyone thinks it's something else please let me know!


  1. It does look like D insulanus. I'm guessing you've ruled out D spadiceus by checking the costa cells.

  2. Yes, cells overlying costa are short.
