Bonsoir
qqes champi sous la dent.... et notamment cette colonie de mini champi (0.5cm) sur une branche de charme au sol (petites spores cyanophiles rondes de <6microns), en général sans stipe à part qqes uns

il y a un Lentinellus créé récemment par PA Moreau et d'autres, il faudrait vérifier si ça colle
Lentinellus herbarum
Basidiospores 5.5–6.5–7.5r4.5–5–6 mm, Q=1.13–
1.45, V=50–130 mm3, ellipsoid to broadly ellipsoid,
rarely subglobose, showing a distinctly amyloid
verruculose ornamentation with low, punctiform to
shortly elongate warts, often aligned in short crests
(Figs 2, 9); suprahilar zone undifferentiated, often
more thinly punctate. Basidia (19–)22–27r7–8 mm,
mostly utriform, wider in the lower part, often somewhat
constricted under the apex and with a move
slender base, filled with small numerous lipoid droplets,
then with 1–3 large yellowish droplets after spore
ejection, with 4 horn-like sterigmata to 7 mm long;
basidioles abundant, mostly clavate, sometimes septate.
Hymenial cystidia (leptocystidia) scarce, sometimes
rare, between the gills cylindrical to narrowly utriform
with large rounded apices and hyaline contents, 25–
33r7–11 mm; on the gill surface (especially towards
the edge) and edge, fusiform with an enlarged base,
22–29r5–7.5 mm (Figs 2–7), often with several
yellowish droplets or condensed amorphous content
reminiscent of chrysocystidia (congophobic and cyanophobic).
Pseudocystidia rather abundant on the edge
and sides, but not emerging, widely cylindrical to clavate,
8–12 mmwide, with refringent content or large droplets
somewhat greenish in Congo red. Subhymenium
8–12 mm thick, filamentous, dense, congophilic. Gill
trama irregular,di- to trimitic with many thick-walled,
skeletal hyphae 4.5–9(–16) mm wide, with 1–1.5(–2) mm
thick yellowish wall, and sometimes locally condensed
refringent content; thin-walled generative hyphae 4.5–
7.5 mm wide, with many septa, sometimes incrusted,
and frequent transitions towards skeletal hyphae;
gloeoplerous hyphae, with radial orientation scarce,
non-septate, filled with small lipoid droplets or homogenous
refractive content. Pileitrama of the same
composition, with a radial parallel structure. Suprapellis
an intricate trichoderm, 50–70 mm thick, congophilic,
made of numerous, mostly unseptate endings
of ascending gloeoplerous hyphae (pseudocystidia)
4–7.5(–9) mm wide, with dense lipoid content, mixed
with repent generative hyphae 2.5–4.5(–5) mm wide,
abundantly branched with scarce to numerous erected
diverticula up to 10–15 r2.5–3.5 mm. Subpellis not
differentiated. In sulfobenzaldehyde, gloeoplerous
hyphae, pileic and hymenial pseudocystidia immediately
turning black, with a diffuse pinkish colouration;
basal content of fusiform hymenial leptocystidia turning
flaky, and greyish. Pigmentation intraparietal on thickwalled
hyphae in the cap and gill tramae; amorphous
incrustations on some generative hyphae in gill and
pileus tramae. In Melzer’s reagent, 5% KOH or cresyl
blue, no colouration on the trama or in any part of
sporophores occurs. In fuchsin, hyphal incrustations
are fixed in colour in the pileipellis of fresh material,
on the surface of non-gloeoplerous hyphae. Clamp
connections not seen in any part of basidioms, including
basidia; dolipore at septa very distinct.
