@Aiwok: Hello. Hypholoma fasciculare has black spores, whereas the mushroom in the photo evidently has brown spores. I think that this mushroom could be Psathyrella piluliformis, but I suggest a category of "Unidentified Psathyrella". I intend to change the identification if there is no feedback.

Hi, I rechecked some sources and even ran an AI and do not (yet) concurr. Keep in mind most of these mushrooms were unusually dry due to the weather, altering the hue. I also checked the proposed genus and species and found it while similar not a good match. E.g. this Psathyrella piluliformis Unfortunately I did not collect any specimen back then. I'd rather keep it as Hypholoma fasciculare now, unless you have some more data. Thanks for your quality assurance work. --Aiwok (talk) 09:25, 9 April 2024 (UTC)[reply]
@Aiwok: Thank you for answering. I do not think that the AI helps in the least to decide the issue, it is very likely to be wrong. The mushrooms in the photo are dry but in an advanced state of decomposition and the red-brown cap colour comes from the real cap colour; it is not a result of decay. Also those places where the gills are visible, they show that the spores are brown, whereas H. fasciculare shows black gills when old or yellow ones when young - H. fasciculare cannot look like this. It cannot take on this reddish colour just because it is dry. I do not know why you think P. piluliformis does not match. Of course, it would be an old one, but I think it is a good fit with its red-brown colour which it often has, for instance see these examples. Anyway I am not saying I can identify the exact species, but I am saying that it is plainly not H. fasciculare. It would be much better to put category "Unidentified Agaricales". Please tell me again what you think. Could you ask someone else? Strobilomyces (talk) 20:24, 14 April 2024 (UTC)[reply]
Hi, The cap color of those mushrooms in my pictures is dominated by spores (as written in the description). You can't see the regular cap color at all. See the leaves on the right side in File:Hypholoma_fasciculare_3.jpg and the leaf in File:Hypholoma fasciculare sporen.jpg. They are also layered with spores in the same color. All those spore prints I found of H. fasciculare matches this color quite well e.g. one online here: File:Hypholoma fasciculare 48023.jpg (also available on mushroomobserver), an example with a thin layer: File:Cuticule hypholoma .jpg, an example with some mushrooms covered in spore and some mostly free: File:A big meeting (48833132377).jpg. I can't explain why H. fasciculare's spores are sometimes described as black or even violet. Is it possibly related to their appearance under a microscope? P. piluliformis on the other hand seems to have pretty dark spores if those depictions are correct: [1], File:Psathyrella piluliformis 238020038.jpg
Hi. I thought that the spores had to be black (or a bit violet) - they certainly are usually when seen on the gills, as seen from the Commons photos for instance. Thank you for investigating. OK, I withdraw my comment. Strobilomyces (talk) 14:26, 29 April 2024 (UTC)[reply]
