Growing in deciduous wood through leaf litter. Several scattered around. Cap 9-14cm, stem 10-14cm. No smell. Foolishly I didn't cut the stem. If it turns yellow at the base then it's a Yellow Stainer, although I have before found old ones that didn't go yellow. ID is very likely. Sporeprint Dark chocolate brown. Spores 4.5-6.5µ x 3.5-5µ.

Growing in grass. several in a cluster. Cap 8-12cm. Faintly unpleasant smell. Flesh not showing any sign of turning yellow, I assume because these were very old specimens. Think these are Yellow Stainers because they are on the site of younger ones from a week or two earlier. ID is almost sure. Sporeprint dark brown perhaps a bit purpley. Spores 4.5-6µ x 3-5.5µ.

Smell a bit unpleasant. I’m assuming that they’re yellow stainers due to the strong yellow colour in the stem base although there are a few other Agricus mushrooms with that feature. ID is very likely.
