Spring Cleaning.
I was cleaning and organizing the shed (a veritable mouse haven) and found two growths on two of the interior walls, which I easily removed intact:

They are similar to wasp (hornet?) nests, but I see no entry point anywhere on the glob. The function of the gray spot on the larger glog is unclear to me. The height of the larger is 4 and 1/4 inches; the diameter of the smaller is 4 and 1/4 inches. There is no sign of inhabitants of any kind. What are they?

A bit of garden news: the raspberry that survived the winter is propagating, by rhizomes, I think, or perhaps by runners or stolons. I am not clear about the difference, but will read the more reliable accounts and I will eventually know.
