Notes: These were growing on the ground/hardwood debris.
Caps were up to ~ 2 cm across and dry.
Did not detect any distinctive odor.
Spore print was whitish to sl creamy.
Spores were amyloid and ~ 8.0-10.9 X 5.0-6.1 microns, ellipsoid to elongate and smooth.
There was numerous Cheilocystidia that varied in shape but much of which I believe would be called “strangulate” and ~ 60 X 5-6 microns.
They looked somewhat like M. capillaripes, but lacked many of the basic characteristics including a conifer habitat.

The technical description of the cheilocystidia needs either further translation or pictures for me, I guess it’s within the realm of possibility that they are somewhat similar.
The leaves in the photos are Madrone and I confirmed today that there is no conifer debris within reasonable range.
A few were left today after a pounding rain and again crushing them, I convinced myself that I got a faint whiff of bleach.
Spores 8.1-11.6 × 4.5-6.2 um, elongated pip-shaped to almost cylindrical, smooth, amyloid. Cheilocystidia 30-70 (-80) x 6-16 × 3.5-5.5
um, as a rule forming a sterile band (lamellar edge homogeneous), fusiform to
subcylindrical, with reddish contents, clamped, mucronate or apically passing
into a simple to furcate neck, or into two necks, but also with rounded apex
(and then clavate), devoid of any additional excrescences. pleurocystidia
numerous, extending over the entire face of the lamelae, similar to the
cheilocystidia but in rare cases with colourless contents. Lamellar trama
brownish vinescent in Melzer’s reagent. Hyphae of the pileipellis 1.8-8 um
wide, clamped, covered with simple to branched, coarse excrescences l-30 x
0.9-3 um which may form dense masses. Hyphae of the cortical layer of the
stipe 2.5-3.5 um wide, clamped, smooth to fairly sparsely and often coarsely
diverticulate, excrescences simple, straight or curved, cylindrical 2.7-8 x l-2
um, terminal cells (not always developed equally well) 4-7 um wide, straight to
curved, variously diverticulate.
Generally on fallen needles of conifers (Juniperus, Pinus, Picea) but occasionally
on litter of deciduous trees (e.g. Quercus). Known from Europe, North
Africa (Maire, 1928: 39, as M. langei, and Malengon & Bertault, l9i5: 229),
and the United States.
This area is devoid of pines and conifers as far as I recall.
Live oak is dominant and I don’t know what those leaves are.
Doesn’t the habitat seem wrong for M. capillaripes? Which is really common right now in deep beds of pine needle duff. But I don’t see pine needles here…
I didn’t notice any color difference on the gill edges but the photos kind of indicate a subtle marginate characteristic.
I did crush a couple but if there was a bleachy odor it was too subdued for me.
Unfortunately, I did not save these and while I didn’t see any obvious Pleurocystidia, I did not make a concerted effort to look for it.
With regard to the Cheilocystidia, I’m seeing mixed signals as to what the M. capillaripes cheilocystidia actually looks like. Is there a definitive description somewhere?
If the gills are marginate, as they appear to be in the second photo, this would put us in the section Rubromarginatae, where nothing described in Maas Geesteranus’s monograph seems to be a better match than M. capillaripes. Maas G says that it “occurs occasionally on litter of deciduous trees”. Cheilocystidia could pass too, I suppose. The absence of odor (nitrous) is a problem; did you crush it before smelling? It would help to know about pleurocystidia too.
