I saw this very fine white fluffy stuff wrapped around and trapped in several plants by the side of a path near some wet meadows beside Lough Neagh. Has anyone any idea what it might be? It reminds me of the fluffy stuff that comes off Salix fragilis in Spring, but surely it's too late in the season for that?
