Size. 1cm to 4cm.
Shape when young. Pins are rounded, Slightly Convex to irregular plane
Shape when mature. Convex
Surface. Moist, Circular Striations where the various colors are like levels from margin to where attached to substrate, very soft like smooth skin almost. I also checked today, and the ground really sucked up the moisture, making the fruiting bodies really dry.

When Dry. Whitish to Greyish-White.

Lamellae: Pores. Pin size. Mostly Equal in Size. Yellowish Tan to Brown.

Stipe: none.

Flesh: Same color as gills, with a brown separation line between lamellae and flesh of pileus. Juicy; taste not explainable but somewhat distinct, only slightly noticeable.

Mycellium: White, very small amounts under peeled bark.

Spores: White, Appearing almost beige under the microscope, pill capsule shaped. No noticeable dextrinoid or amyloid reaction, they just appeared to pick up the yellow hue of Iodine.

Hard to tell

Idk as shown in the two new images I uploaded of the cross section, they dont show any noticable hair. But it is possible and almost seems that their is hair that is so short and dense that it just seems to be a smooth hairless texture.

Its hard to tell

I guess I would consider it almost velvety like you would consider T. villosa. That seems pretty spot on.

Are you saying the cap is bald and smooth?

Your first two pictures I snagged and color balanced, sharpened a bit, etc..
These seem to be hairy to me. The concentric bands of ridges and furrows show it particularly. unless I’m crazy which is possible.

When I found Trametes suaveolens it had a similar feel, very soft and smooth. I would have used the word tomentose to describe that, which I would also use to describe your first two pictures.
For whatever that’s worth :)

edit* I’d have to ask which of the specimens in your pictures that is a cross section of. Is it of the older flatter ones and the pores are all blown out and toothed also?

No hair.

(Hirsuta means hairy)
Insomnia’s notes mentioned ‘very soft like skin’. Insomnia, did you get a picture of a cross section?
I can agree with T. villosa.

the pore surface…

is tooth-like, which suggests Trametes villosa.
