The pileus appears wet because it had been raining, the surface should be described as dry. The specimens were in less than ideal condition when found so while I think the cystidia are cheilocystidia I had difficulty getting a good section. If it might be helpful, I can give it another go with the dried material. Thanks for the replies.

germpore in Pholiota spores

in the Pholiota species with light coloured spores, such as Ph. lenta, the germ pore can be quite invisible; it is more that you know that it should be there, than that it is visible.
For Ph. tuberculosa the descriptions give: no germ pore.
The shape of the spores is definitely Pholiota-like, and i don’t see any ornamentation on the spores.

If the spores really don’t have a germ pore, which seems likely, and the mushroom is wet I’d go with Gymnopilus.

The cystidia fits Gymnopilus. It would be helpful if you label your micrographs so I know which part of the mushroom I am looking at. When I photograph microscopic features I also take pictures of little bits of paper with the different microscopic features so when I upload them I know which parts of the mushroom the micrographs refer to.

Pholiota tuberculosa has a dry pileus surface and lacks pleurocystidia, but the old basidia turn yellow in in KOH.
the shape of the cheilocystidia fits Ph. tuberculosa very well.

are yellow brown with no germ pore, I would expect spores this color to produce an orange spore print in mass. Pleuro- and Cheilocystidia abundant.
