In Dr. Harry Thiers monograph of the boletes of California (California
Mushrooms, A Field Guide to the Boletes, Hafner Press, 1975,
out-of-print), one white Leccinum is listed, _Leccinum californicum_.
But it is listed as being known only from the type locality in El
Dorado Co. and having a context that is "unchanging when exposed". The
spores of L. californicum are listed as 14.5-17.5 X 5.5-6.5 microns.
Send Dr. Thiers a good description. He can be reached via email at
