i spread some king stropharia spawn among layers of cardboard, wood chips, and paper a month or two ago, and recently I have been seeing red mushrooms in the area (some directly in the sown area and others a little further away in forest litter).
these seem more red than i was expecting from wine caps. in most photos they seem to be burgundy. these are quite red, and certainly they are brittlegills/russula.of some sort-- but i am uncertain if they are the wine caps!
Hi Eon, It does ring a number of Rus. Sp. bells.
Are you able to get a picture of the underside?
Do the gills attach directly to the stipe or is there a gap?
It the top 'slimey' or rough?
If you crush a piece does it stain black, brown, or yellow?
