Rate of drying..

… I’ve notice that with many Amanitas for example, the gills can become yellowish, especially at the gill edge if dried slowly. When I put them in the dehydrator at the proper temp., there is no color change noticed. Perhaps there is a bacterial element involved?

… can provide us with important information about a mushroom’s morphological characteristics, and is one area that probably deserves more rigorous study.

Do you have any pics of dried T. sulfureoides gills I could see?

but the gills, flesh and stipe are not yellow. T. sulfureoides gills remain yellow.

It may be another Tricholomopsis.

These are growing from wood…

It was an old eastern hemlock log. I have little doubt it is the same species as this, which I found last year at the same time, same location. If you look at the mushroom in the middle(in the photo below)you can see the reddening starting to occur on the margin.

(based on photos on MO) Tricholomopsis rutilans and T. sulfureoides are both found “…or in small groups on or near rotting conifers, wood chips, and humus rich in lignin; widely distributed.” Arora places both under T. rutilans. “…and T. sulfureoides, partial to hemlock, with an evanescent veil, and a cap that develops small brownish scales or streaks in age.”

I found T. sulfureoides once growing from an old-growth Western hemlock lock 4 feet off the ground. The tree was 5 feet diameter. Bright yellow cap with tan fibrils, and bright yellow gills. Almost like a wood-growing chanterelle.

Not on wood?

I don’t understand your first comment. These specimens were pretty dried out and I think that is why you see the color change on the gills. The original description mentions this.

Gills should not change color from bright sulphur-yellow. Probably not T. sulphureoides.
