Fairy Ring and Tree Cattle

There's nothing substantial to this post, but I noticed recently that I have a fairy ring in the yard.  This isn't a very good picture--it would be nicer if the grass was shorter, but the same rain that made the mushrooms bloom also made the grass take off.  Once mowed, the ring is much less apparent.

This is the first year I have noticed this ring, and it is relatively small--less than five feet across.  The mushrooms themselves are fairly large, and I have no idea what kind they are. I assume they will be back next year, in a somewhat larger circle.  We shall see.

This is near the blackberries growing near my garage that I referred to a couple of months ago.  Before the blackberry bushes, that spot had a big rose bush that eventually keeled over, then the rose bush rootstock grew up and bloomed for a few years.  As a nearby crepe myrtle has grown up, it has gotten too shaded, so the rootstock rose has been ailing, as well.  Finally, I pulled everything out.  When I yanked up some of the old canes, I saw some very curious little bugs.  They moved very fast but in herd fashion--like antelope or cattle.  I poked around on Google for a while and found that's exactly what they're called: tree cattle, aka bark lice.  I saw the nymph form.  Eventually, they ran away.

Before this starts to resemble a Jim's Journal strip (unless it's already too late), I should stop.
