This species has been plentiful in this area for the last week or so. Spores ~ 12.0-13.2 X 8.0-9.1 microns, ellipsoid and moderately rough. California material may be different from what these have been traditionally called, but I'll stay with the old name until more definitive studies have been made. Edit11-20-2016; the spores for C. seidiae are listed as (12)12.5-14.5(15) X (7.5)8-9 microns. They are wider than for C. vanduzerensis and these match the description better. Browner caps are also characteristic for C. seidiae.
