Hello Rosie,
These are rhizomes (uncharred) and nodules (possible charred) of Equisetum
At least that's what I think
Check the anatomy of the rhizome cells. If they are thick-walled
rectangular to elongated cells with angular ends of the short cells then
you have the best chance for Equisetum rhizomes.
All the best
