The mushroom was kept in a temperature-and-humidity-controlled herbarium with 5,000 other collections. Perhaps it was exposed to moisture in the mail. I’m glad you are willing to try again.

Yes, I just got to the mushroom this morning.

It seemed really dry when I sent it, especially since it was the smallest of the batch. Maybe the bag wasn’t sealed well, and it got into a humid environment. Were you just getting around to looking at it after 4 months? I’ll try again if I come across another specimen.

Brian, I received this specimen, but it looks like it was not entirely dry when it went into the plastic bag.

I’m not going to try to work with it.

to me the photo looked somewhat like A. citrina…. except for the lined cap margin. So I’m wondering if this may be an example of A. brunnescens var. straminea. Ret describes this species as sort of a cross between brunnescens and citrina.


But, the lined cap margin in this obs does still appear as a problem. Perhaps the development of the sulcate margin is due to the cap margin becoming partially dry and somewhat collapsed atop/between the gills?
