Re:A discomycete, inner surface of loose bark of Alnus
This is also a Rutstroemia of the group R. firma. But the substrate (Alnus) and your drawing of the excipulum which I interpret as abundant gel between the cells (I am not sure) indicate a different species foir which I have no name, but for which usually the name R. firma (or Poculum firmum) is applied. R. alni is different by much larger spores. About the latter Urs Roffler and I have recently published an article in SZP (Switzerland).
