This one — I only found the one, and the color is different than any other found, but not by much. This one is dull yellow, but with a brown tone, and more brown in the disc. But what really separated this one as different was the taste, it is very faintly acrid. It is mild at first, and then after 5-10 secs. it is like a hint of acrid. You can keep it on the tongue for awhile, and you just think, oh yeah, that is acrid isn’t it? But you don’t need to spit it out. Not like other acrid ones, like R. cremoricolor, where withing secs. I am trying to get it all off my tongue.
This one seems fully mature and open, and the gills are still white. With the brown tones, and the faintly acrid taste, this is well described in Theirs as R. ochroleuca. The one problem is that he describes this one as found in the Fir forests of northern Humboldt Co. So, this one is far a field here, being found in San Mateo Co. under live oak.
But I don’t know what else to call it.
