Little puffball like fungi on a treestump ,about 20mm high and 15mm in diameter.
No identification made yet.
No interactions present.
I would say it was a puffball but hard to say from photo which one it is.If possible try to get a good close clear shot and size of fungi if you find any more also photos of underside (gills,pores,spines,) and stem ,habitat help too.
