Some notes were sent into me by Dr. Else C. Vellinga:
Your picture of Lepiota seminuda in fact is a species in the L. sequioarum complex. Cystolepiota seminuda is small (caps up to half an inch, more or less), with a rounded cap and a fine granulose covering, which in young fruitbodies hangs down the cap margin in triangular teeth. The stipe is thin, also finely powdery, with a wine-red tinge to it under the cover. A ring is not really present, there may be traces left on the stipe where the cap broke off from the stipe Your specimen here is bigger, with a flatter cap, radially fibrillose silky, with a prominent ring on the stipe (and lots of microscopic characters which also distinguish it from C. seminuda). Unfortunately, what has been called L. sequoiarum here is in fact a complex of 5 or 6 different species. I’m in the midst of figuring it all out.
So, thanks to Else, and what do you know?
