Rod, as a matter of interest I have lightened the original image, but as you will notice when this is done the “whites” on the Stipe are partially washed out. I , from memory, think this cap colour was close to what I saw at the time. The light was challenging, with the cloud cover and...

I’m very much obliged for the extra photograph.

Very best,

Rod, comment

Rod, it was getting so dark with storm clouds I was ready to head for home. The track is a bit nasty in wet weather, and it is a bit of a distance from civilisation. I relied on the “Auto White Balance” setting on the camera in this instance. Auto White Balance although a good average, has its limitations, and that is why I use the white balance colour card. (most of the time.)I can however photograph it for you before posting the dried specimen. I have made a note to do so. kk

Ian, did you happen to get a shot of the top of the cap full on?

The original description of luteofusca offers two colors or a range of colors that are apparently based on Ridgway’s color names. In both cases the Ridgway names are modified indicating that the colors of the cap are paler or otherwise different from the Ridgway colors.

The cap seems very dark to me in the first photograph; however, maybe the angle and shadowing are altering the color….??

Very best,

Rod

are more often seen in amyloid-spored taxa than in inamyloid-spored taxa. So I think there is a reasonable argument for placing this material in the Validae.

I’m looking forward to the possibility of seen this material, because I’m pretty sure I have not physically handled a specimen of this before.

I don’t see any sign of yellow volva on the cap, or on the bulb, or on the underside of the edge of the skirt (partial veil). If it was once yellow, it has uniformly turned to gray.

I need to learn more about this material.

Very best,

Rod
