Psathyrella maculata

[BubikolRamios]

Local page points to Psathyrella maculata being very similar to Lacrymaria lacrymabunda.

All namely Psathyrella maculata, except the red squared part. Local page says for Psathyrella maculata that there should be black dots on edges of gills, but as one can see and then speculate, black drops on Lacrymaria lacrymabunda could also dry out to that, or not ?

Yes, in Lacrymaria lacrymabunda, the black droplets can also dry right on the gill edges and cause black spots there. However, the gill edges as a whole remain whitish and stand out in color from the gill surfaces.
Unfortunately, in my photos, the image of the gills of the most mature fruiting body isn’t very clear.
The marbled gill surfaces are typical of mature L. l.

Looking at the posted photos, however, I also see marbled gill surfaces in the details that are supposed to depict Psathyrella maculata!
I don’t think the photos have been correctly identified!
(I don´t know what it is ... maybe a somehow "strange-looking" Lacrymaria lacrymabunda. But there is another species (besides L. pyrrotricha, which is more vividly coloured and less smooth in my opinion): Lacrymaria glareosa - but I can´t tell them apart, microsc. features needed, growing often in poor soil, with pebbles.)

In German-language identification guides, Psathyrella maculata is not described as having black droplets or marbled gills, nor are such features shown in photos. The gills darken with maturity, while the edges remain lighter. The mushroom is rather rare in Germany; I’ve found it twice (from the same location). Darker, tightly adpressed scales on the cap, which stand out clearly against the background are typical ("dirty patches")
This species grows on wood (sometimes also on buried wood). It often occurs together with Kuehneromyces mutabilis on the same piece of wood.
In Germany they say Psathyrella maculata might be mixed up with Psathyrella caput-medusae, my fruiting bodies of P.m. closely resembled Psathyrella cotonea - but none of these species really resemble L.l.

Good photos of Psathyrella maculata where you can also see the gills (my specimens were smaller, relatively light in color, and less mature)

Thanks, found one of my old photos that exhibits exactly that, white gills edge and marbled surface at Lacrymaria lacrymabunda
Will check your doubts about red square part at OP image. Local page says droplets can be seen at Lacrymaria and not at Psathyrella, namely.
