Recognized by sight: Even assuming this is subgenus Homophron, section Homophron which is kind of hard without seeing pluerocystidia (The hyaline spores match, but other groups can have hyaline spores too). We will still need spore sizes and to see the caulocystidia for a confident ID…

I’ll give these pink-spored Psaths a closer look next time I find some.

Yes.

Using the Smith key, assuming the subgenus is right (Which we need to see thickwalled pleurocystidia to confirm), with hyaline spores (sect. Homophron) and red spores, the choices seem to be:

P. rhodospora (Staining red at the stem base, so maybe not that)
P. littenii (Many pleurocystidia showing refractive contents in KOH and cheilocystidia 20-65 X 10-25 µm)
P. sublateritia (Distinguished from P. conissans with stipe (5-)8-15(-20) mm thick & many caulocystidia 40-90 X 6-12 µm & ventricose at the base with a very long neck)
P. conissans (Distinguished from P. sublateritia with stipe 2.5-5 mm thick and caulocystidia subvesiculose to clavate and up to 70 X 20 µm)

Also, seems I misread the key, spore size would be more important if these had brown spores…

Yes.

Byrain, do you know any Psath other than…

P. conissans that has a pink spore print?
