In sinicoflava and similar species, the volva is often gray and breaking up…

a bit by the time the cap breaks through it. I have seen specimens that were not quite mature in which the volva was still not very gray. Nevertheless, the graying of the volva is pronounced and happens before the mushroom could be called “old.” The graying of the gills is much slower in my experience.

When I described the species, it was not uncommon for people to find it on forays. However, it has been years since I saw more than one or two in fresh condition in a full year. May be they occur cyclically?

Thanks for keeping an eye out.

Very best,

Rod

Thanks, Rod

Guess I’ll just have to hope I find another so I can check out whether or not the gills and volva gray. How long does the process take? I had these specimens for about 4 hours while photographing these and others and taking measurements.

Regards,

Terri

It seems to lack the orange and deeper brown colors of the american “fulva.”

The rusty spots on the volva as well.

Very best,

I looked at my field notes again and I had noted that the volval remains seemed to stain brownish but I wasn’t certain if that was from something in the soil. If so this is probably fulva I think.

I’m afraid I can’t say as I found this enroute to NEMF and had no way to dry it so I didn’t keep it. At first I thought it was A. fulva but the green tan cap color of A. sinicoflava seemed a better fit after looking at your site. Maybe I’ll find another at which time I will check that out. Thanks for the comment.

Regards,

Teresa

For sinicoflava the volval sac should turn distinctly gray from the top…

down. It would also become less pliable and start to crack and break up.

Let me know if things progress that way or not.

I’m curious.

Very best,

Rod
