i’ll update the observation when i go out again tomorrow or monday.
i thought they were Hypholoma fasciculare and didn’t really give them a second thought.
they were growing in and around oaks and hardwood debris in mixed forest.
if they are fruiting i’ll collect a few specimens.

you have something to say here, you’re the one that actually saw them. I expected you to say that you saw some yellow green on them, because the luminosity on photos could hide the true color. And the cap, what was the color?

H. lateritium has red to btick red caps and is paler at the margin. Dave perhaps you found a different species, or an extremely faded one. If you enlarge the photo and zoom in, you may dectect some yellowish-green colorations along thwe margin and at the stipe apex. Perhaps these mushrooms changed gill color to the purpleish shade as seen in the photos. If that is the case I would say they are H. fasciculare.

I suppose that…

I’ll need to try to remember to taste the ones that do not obviously key out as capnoides or lateritium based upon color, stature, and substrate.

The link contains another good discussion about these two species names.

I don’t see much yellow on the gills in this obs (130586), maybe just a touch of yellow along the margin. For fasciculare or subvirde to show so little yellow/green on the gills, I think the mushrooms should be more mature than the ones seen here.

I wouldn’t rely on substrate.

Both can be found on deciduous and coniferous wood, H. lateritium especially on fir and spruce. H. capnoides rather seldom, mainly on oak.
Both can have bitter-tasting flesh although very very rare in capnoides.
But IMO H. lateritium always has stout bigger fruitbodies, the odor is different and the cap color much brighter, more vivid not blunt.

H. capnoides and…

H. lateritium (formerly H. sublateritium) are quite similar. Lateritium is generally reported as having a more reddish color on the cap. But I have seen examples of lateritium with very pale cap color. My understanding is that the two species may be distinguished by substate; capnoides on conifer wood and lateritium on hardwood. MushroomExpert says, “Smith, Smith & Weber (1979) report the possibility of mushrooms intergrading between Hypholoma capnoides and Hypholoma sublateritium.”

“Lamellae adnate, close; color firstly sulphur yellow, then dark reddish brown” like H. lateritium I don’t see any sulphur yellow tones on these.

“Stipe (7)14-66×1-4 mm, central, cylindrical, with little expanded base; color sulphur yellow” idem.

“Pileus 4-35 (-45) mm diam., first conical, convex, then finally flattened, with or without an umbo; color yellow (5Y 7/6-7/8) in younger stages then sulphur yellow; surface smooth, subviscid to dry; margin regular, little or not striate, rarely bearing velar remnants; context thin, greenish. Lamellae adnate, close; color firstly sulphur yellow, then dark reddish brown (5YR 2.5/2-3/2) with the maturity of basidiospores; margin regular, with the same color as the sides. Stipe (7)14-66×1-4 mm, central, cylindrical, with little expanded base; color sulphur yellow; surface dry to little humid, longitudinally striate; basal mycelium whitish, poorly developed, rhizomorphs absent. Veil arachnoid, very ephemeral, observed in earlier stages and absent in adult basidiomata. Spore print dark vinaceous brown.Basidiospores (5.5-)6-8(-9)× 3.55 µm, (Q =1.50-2.00, Qm =1.71, n =148), ellipsoid to slightly ovoid both in side and frontal view; smooth and thick-walled, with truncate germ-pore; color yellowish brown in KOH. Basidia 15-23×4.5-7 µm, clavate, bearing four sterigmata. Pleurocystidia (19)25-38(-47)×(5.5-) 8-12 µm, as chrysocystidia, fusoid to clavate, with mucronate apex; smooth and thin-walled, with yellowish amorphous content, numerous in the gill sides. Cheilocystidia (13-)18-22(-26)×6-8 µm, as leptocystidia, utriform to cylindrical, with rounded apex; hyaline, lacking yellowish contents; hard to find in dry specimens. Pileipellis composed by parallel, poorly gelatinized hyphae, 5-9 µm diam., with walls slightly thickened and incrusted by yellowish pigments. Hypodermium cellular, formed by subglobose hyphae, 15-29 µm diam. hyphae, with walls thickened and incrusted by yellowish pigments. Context composed of interwoven, hyaline hyphae, smooth and thin-walled, 5-10 µm diam. Hymenophoral trama regular, formed by hyphae with slightly incrusted walls, yellowish in KOH, 3-7(-10) µm diam. Stipitipellis composed of parallel hyphae, smooth and thin-walled, 3-7 µm diam. Caulocystidia 30-44(-60)×8-10 µm, as chrysocystidia, similar to the pleurocystidia; scattered in the stipe apex, hard to find in dry specimens. Clamp connections present in most septa.

Habitat: cespitose to fasciculate on wood of Eucalyptus spp., Araucaria angustifolia (Bertol.) O. Ktze., Prunus sellowii Hoehne, among others.

Distribution: Widespread in tropical and subtropical areas of Africa (Pegler 1977; Reid & Eicker 1999), Asia (Pegler 1986), Central America (Pegler 1983), Europe (Krieglsteiner & Enderle 1986), North America (Smith 1951), and South America (Dennis 1970; Pulido 1983).

H. lateritium

Yes, it could also be the H. lateritium. I did not refer to that because it’s more likely confusion between H. fasciculare and H capnoides.

you might be right…

it seems H. capnoides to me from what I see.
