Hyalosphenia papilio variant

[cuxlander]

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
