If it is this species

it would be new to Croatia. But then again that does not tell much it is a country in a stage of fungal knowledge in the very beginning.

Description of Infundibulicybe mediterranea:
By: Irene Andersson (irenea)

Pileus 1–8 cm broad, not very fleshy, subelastic, typically plane at first with disk shallowly depressed and margin incurved, often with a small umbo, disk becoming umbilicate or deeply depressed, finally infundibuliform, margin upturned or arched, sometimes lobed or incised and undulate, not hygrophanous, occasionally appearing as hygrophanous due to water soaking, subglabrous to matted fibrillose, rarely diffracted-scaly near the disk, at first dark chestnut brown to brown (Bc 20 dark brick or 19 bay), then paler (Bc 15 brick, 10 cinnamon, 14 rusty-tawny and 13 rust). Surface light brown with a KOH drop in both fresh and dried basidiomes. Lamellae crowded to close, thin, narrow, sometimes forked or intervenose, white; edges even, entire, concolorous. Stipe 1.5–5 × 0.3–0.5 cm, short, central or subexcentric, equal or with a somewhat enlarged base, concolorous with the pileus or slightly paler (Bc 11 sienne, 13 rust, 10 cinnamon), white-pruinose, glabrous or slightly longitudinally striate, stuffed with white medulla, becoming hollow; the base often with copious white tomentum with adhering leaves and woody debris. Context thin, elastic, white in the pileus, watery brown in the stipe, unchanging. Odor and flavor fungoid; edible, good. Spore print white.

Spores 4.5–6 × 3–4 μm, on average 5.5 × 3.8 μm, sublacrymoid or lacrymoid in all sides, hyaline, smooth, inamyloid, indextrinoid, acianophilous, with several oil drops and a small apiculus (FIG. 2a⇑). Basidia 20–25 × 6–7.5 μm, four-spored, clavate, often with a ventral constriction (FIG. 2b⇑). Hymenophoral trama regular in young stages, but subirregular to irregular in aged basidiomata, made up of hyaline, elongate, cylindrical hyphae. Cystidia and marginal cells absent. Pileipellis a xerocutis made up of loosely interwoven, often protruding brown-encrusted hyphae, these 3–16 μm diam, cylindrical to subclavate (FIG. 2c⇑). Thromboplerous hyphae not seen. Clamp connections present at nearly all septa.

Habitat: scattered, gregarious, often in arcs, occasionally subcaespitose on leaves and humus, under broadleaf trees (Quercus suber, Q. ilex). February–December. Common in Sardinia but seen also in southern France, Corsica and Morocco.

Interesting.

What are the features of this?

Yes I know.

That’s the problem with Clitocybe: no reliable macro details, no reliable micro details. A hard thing to crack.
I’ll leave it as squamulosa for the moment in defeat of a better option.

The other one

(obs 131871) – a bit more squamulosa-like, but… hard to tell.
Micro characters are usually not helpful either.

And the other one?

This also looks somewhat odd.

I wonder
By: Irene Andersson (irenea)

how many unknown species we have in this group… These look too brown and too smooth for squamulosa, but I have no other idea.
