This fits Caulorhiza umbonata quite well except for one tiny detail…there’s nary a redwood in sight. Not even close. So, is there a Caulorhiza that likes live oak? If not, what else might fit? The gills were pale yellow ochre and badly weathered. They probably were attached. Pileus 4.5cm across, Stipe .6cm at apex, and total height 12 cm.
Oops, I missed that little note in Arora.
12/24/08: I’ve found several of these this new season in the same area that I originally found this individual. The location is an old cemetery and I realize that all but one that I’ve found were fruiting right next to wood framing around grave sites. It seems possible if not likely that those wood frames were made from Redwood.

For the record, Caulorhiza umbonata does not need to be growing around Redwood trees…
I have seen C. umbonata growing out of a pile of redwood chippings and mulch that was dumped in a median in a parking lot. I considered if there were redwoods nearby (i think there were), however, the pseudorhiza was not rooting straight down. The pile of redwood was shallow, and the stipe took a 90 degree angle as the redwood litter thinned below. As you can imagine, it was a total pain in the ass to uproot!!
So basically, it seems the stipe was growing sideways to consolidate for the shallow depth of redwood matter. All sources I’ve read say C. umbonata is saprobic (though perhaps it also has the potential to become symbiotic).

This is not necessarily relevant to this observation, however, i thought it should be noted that redwoods don’t need to be growing around an area, for the Redwood Rooter to show up.

C. hygrophoroides?

C. hygrophoroides is a Peck species described from NY in 1879. It is a hardwood lover, according to DArora.
