Panaeolus cyanescens

I think this collection is another example of P. cyanescens even though the umbo is very strikng.
P. cambodginiensis is described as having a dark colored cap, this specimen has a very pale/white cap. Also, P. cambodginiensis is described as having very thin metuloids with less pigmentation. The metuloids observed here were highly variable, but most were thick walled. Spores (13.1 × 10.3 microns; Q= 1.3) were also within the described range for P. cyanescens.
