is that sublateritia is said to grow on hardwoods, otherwise it’s a very good suggestion (reminding of spadicea, but with brick coloured spore print).
But Smith has over 400 species in his monograph “The North American species of Psathyrella” – and there are so many look-alikes..
The description of sublateritia is here, starting on page 239:

One special microcharacter to look for, is the long-necked caulocystidia.

keys out to Psathyrella sublateritia

This keys out in Mushrooms Demystified under Psathyrella to Psathyrella sublateritia for which I can not find any info about other than the spores are distinctly reddish-tinted, which they are. The cap is up to 9 cm broad. The stipe is as much as 15 cm long and 2 cm thick. I did find a reference to P. sublateritia in Lincoff’s Audubon Society Field Guide to North American Mushrooms. He states that P. sublateritia is possibly a variety of P. conissans, has a brick red spore print and is somewhat larger.
