Observation 18387: Bolbitius vitellinus (Pers.) Fr.

Notes:
Kind of fragile but not slimy.

Spores brown, smooth, ellipsoid-truncate with a large germ pore.

Brachybasidioles present in the pileipellis.

Cheilocystidia is present but no pleurocystidia was observed.

Cap surface?

Did you check the quality of the cap surface? With the brown spore print and the large germ pore, this could point to Conocybe and such.

Not Entoloma

Entoloma spores are always somewhat angular, and there is no germ pore. Also, if it was Entoloma, the spores would be at least salmon-brown, not just brown.
