Hello,
Hyalosphenia papilio as we know it:
In 2007, Chaim Glück described a variation of Hyalosphenia papilio in which the shell is heavily dented below the pores. During his studies this variation proliferated and became dominant in his examined area.
In 2022 I found the same variation in large numbers in samples of peat moss.
Recently (2022) this variation was also found in Estonia.
It appears to be a stable variant.
Cheers,
Hans
