Who: jdoe

No specimen available

Notes:
Hygrophaneous- brown when whet buff with brown center when dry, bruises blue with green tint at times, purple black spore print, caps slightly umbonate and lumpy planar with age, some very wavy. Separable pellicle. Cap 15-50 mm and stipe 20-50 mm or so.

These were found growing in several large clusters on year old mulch in a landscaped area growing amongst gingo and ivy. Sun obstructed in this area most of the day and a mulched Hill is directly adjacent that provides significant runoff water.

I am not sure if these are caerulescens, caerulipes, ovoideocystidiata, or something different.

compare to this find which is from rhode island- seems to macroscopically resemble p. stuntzii, but microscopically match ovoideocystidiata (according to alan rockefeller), though another user on shroomery who is trustworthy carried out further microscopy and claimed that it matched p. stuntzii microscopically as well.

anyway, cool find.

This will give you guidance in performing microscopy if you wish to:

The best two things you can do to compare your collection to Psilocybe stuntzii is –
Find and examine the following description, which may be hosted elsewhere: Mycologia 68(6): 1261 (1977)
Compare visually to other collections from this site and others if you prefer.

Also, if you have or can briefly borrow a microscope, you can photograph and measure the spores and cystidia.

Regarding the rareness of finding this species outside its normal zone, these things happen in biology and shouldn’t be too large of an alarm.

Also, Psilocybe stuntzii is somewhat distinguishable by boths its blue ring on the stipe, and its seperable gelatin-like pellicle when fresh.

How can I distinguish stuntzii from other species? This matches previous stuntzii observations well however it seems stuntzii has not been documented outside of the PNW while cyanescens, ovoidiocystidiata, and others have been. Would microscopic features help?

…do a comparison with observations of Psilocybe stuntzii.
