Destem two of them so its just the cap
Gently put on on a white paper and the other on black paper
Cover both with a glass
Leave for like 8 hours
Spore print will show up on at least one of them
Discussion
Im not convinced these are Armillaria Mellea, whats the habitat?
I don't know if its useful. My paper wasn't just black and the little moth interferes. 
The fact the spores are white rules out some things
Yeah. Nothing at all showed up on the white paper either. Because they were white obviously.
I thought it might have been "Soapy Knight" , but I've since abandoned that hypothesis.
