There is a strong yellow component in the cap color…

of A. sinicoflava. It is a strange color, some cameras “find” red in this color. I have always thought that there was a significant olivaceous tint. I have learned that grayish yellow seems olivaceous without true green in the pigment.

Also, instead of having a ring of volval fragments on the stem, sinicoflava is usually found with a sac at the base. The sac may be white in young material, but becomes gray (and cracks) from the top down as the mushroom ages.

Very best,


of course

it was different colors and little

I thought maybe sincoflava

I think this is distinct from the material examined so far for the rhacopus-like taxa.

If you should find this again, I would be very interested in examining such material.

Very best,

The images seem almost silvery gray or bluish gray to me. Is this an accurate representation of the color that you saw?

This material belongs to the group of taxa similar to A. rhacopus. We had many collections of this species at the Northeast Mycological Federation’s “Sam Ristich Foray” last weekend in Maine.

Very best,
