Recognized by sight: Looks like a black staining Hygrocybe. Doesn’t look like the stipe is slimy which would indicate H. singeri and it’s reddish and I would guess live oaks are a lot more like than redwoods in southern California suggesting H. nigrescens over H. conica. However, I have seen a black staining Hygrocybe in southern California growing in a lawn (observation 310) which I’ve referred to as H. conica.
Used references: Looked at the page on H. conica on Mykoweb: http://mykoweb.com/CAF/species/Hygrocybe_conica.html.

is a large red capped species with a orange margin. I have only seen it in Live Oak/Bay habitat in interior Humboldt Co.

H. nigerescens is a European name, I am not sure we get it in California. I am not convinced that how viscid the stipe is should be considered taxonomically significant. It gets less viscid as it dries out. H. singeri is a name from California, so I think it is very likely to be that one.
