This is mostly just a guess/semi informed attempt at an ID, but I think the dark red/white ones are Earliella scabrosa and the brown one may be in the Genus Microporos or possibly Lentinus brumalis (pictures range from rather similar to quite different, so I'm nowhere near 100% sure)

I think the photo of the gills would likely be the Earliella

I'm not going to make an uneducated guess, but I will say when identifing mushrooms it's useful to get an overall shot (like you've provided), but also a closer shot of the mushrooms and a shot of the underside of the mushroom (where the gills/pores are) as a lot of the key idenfying/differentiating features aren't super obvious from a distance

Edit: tbh I think you've got two distinct mushrooms in the photo; the more red and pale bracket fungus and the more brown and uniform fungus closest to the camera

Edit2: were the mushrooms on stems or were the visible parts in the photo connected directly to the wood?

Wow that view is stunning!

Can you explain what makes it gravel bike as opposed to a mountain/off-road bike, or are the terms effectively synonymous?

Lots of them will have some minor fluorescence, but some exhibit in a much greater/uniform form:

I know a common one that carries this similar type of yellow/green fluorescence are sulphur tuft mushrooms, I believe it is to do with the toxic alkaloids which they contain (but I could be wrong)
