It was growing in a tray of flower-seedlings, where I had shoved the
packet in
the edge of the soil and it had got damp.

(It's about 1/5" tall, with a slightly shaggy top, nothing of note under
the
soil - that's the soil it came from on top of the packet)

Maybe this one?

First thought was yes - the third of the photos on that page looks just
like it. But I think the gills are darker in mine than that one.

But thank you. I'm only looking for curiosity sake, so if I don't get
an exact match it's not a problem.
