The fungi living on the oak tree exude liquid. A clear ooze.
A creature, whose name I don't know, a spinner but perhaps not a spider, has extruded these webs along the top of the clipped yew hedge, pushed out fine threads through tiny openings. The webs mist the severe line.
I also think of the way breath clouds a window: a category different from exudations and extrusions. But back to the Realm of Ooze and Extrusion, what are you thinking of? Tell me, please.
