that you suspect may represent the bisporigera group, a couple drops of KOH goes a long way (yellow reaction on the cap surface of bisporigera). Also, the spores of bisporigera are amyloid whereas any species from Vaginatae has non-amyloid spores.
had an annulus before I picked it but not when found. That’s why I only propose could be. Found lots of goodies that day.
if this may have had a ring that dropped off the stipe. Cap appears to lack marginal striations, which would be unusual for section Vaginatae. Also, stark white color and yellow stain (on stipe) suggest this may represent the bisporigera complex. Stipe base appears to feature a bulb.
with the staining of bisporigera in KOH but I never considered the lack of striations in this specimen. Thanks for the info. As is my habit when I find too many species I often forget to expand my notes and do chem. tests.
