Dear Christin,
It does also look to me as root periderm of a woody plant, possible shrub
or dwarf shrub. ‘’The small cells oriented in horizontal rows’’ plus the
shape of the cells, quite regular with straight or slightly diagonal short
cells, resembles the cell pattern of some Ericaceae (for example various
Vaccinium species and Ledum palustre) periderm. However not Calluna and
not Andromeda – the cells are much irregular in both. Empetrum nigrum
periderm also reveals quite regular cell pattern with cells 40-50µm in
length and c.20µm width (which is much of the size of the cells on your
specimen).
If peat formation is something to consider about your organic layer,
perhaps the above suggestion is of some use.
With kind regards
Lucy
