Identification

@Japonica and Thiotrix: Hello. This mushroom does not look like Marasmius oreades and I believe that it must be Leratiomyces ceres.

1. The deep orange/brownish cap colour is not right for M. oreades.
2. In the photo the gills are turning grey as the dark spores start to mature.
3. The stem in the photo is yellow, thick and quite shaggy, not like that of M. oreades, which is slim and smooth.
4. M. oreades normally grows in grass but L. ceres is found in garden mulch or garden soil debris, which seems to fit well with the photo.

I hope it is OK with you if I change the identification accordingly. Strobilomyces (talk) 15:54, 9 October 2021 (UTC)

Hello Strobilomyces, you must be joking! L. ceres is annulated/armillated aka "Stropharia aurantiaca" https://www.mushroomexpert.com/leratiomyces_ceres.html

- The stipe is slim and smooth - Spore print and gills are whitish Anyway, collected specimens have been identified by SMF in the field...

I agree on one point, though, they are not typical. So, I would discard the file.

Thank you for your time--Japonica (talk) 02:40, 10 October 2021 (UTC)

@Japonica: Hello, Japonica. No, I am not joking. There has been some confusion with Leratiomyces squamosus var. thaustus (especially under the name aurantica), which has more of a ring and coloured scales . Please read the naming section of the English wiki article on that mushroom for an explanation of this, which is also mentioned by Kuo in the link you give. The Commons photo agrees well with Kuo's images of the true L. ceres (except the gill colour). In the photo, and also on the true L. ceres, the stem is thick and somewhat shaggy. Although the gills in the photo are whitish, the mushrooms seem young and there is a blackish colouration as if the dark spore colour is starting to come through - a bit like Hypholoma lateritium. The shape of the gills and the gill attachment are not at all like M. oreades.

I belong to the SMF (Société Mycologique de France) and in my experience its members can sometimes make mistakes in the field.

Anyway the differences seem to me to be much too big for the species in the photo to be M. oreades.

It is very difficult to get files deleted on Commons, perhaps rightly so, but instead one can give them a vague category such as "Unidentified Agaricales". Strobilomyces (talk) 20:19, 19 October 2021 (UTC)
