The Sickener

I would have to look that up, too. Can't tell without. But as long as my PC and my connection playing funny tricks on me, I am kinda cuffed. I try to keep it in mind...

what do you think from russula nitida (has grooves) and the color variate from bright to darker red with the center always somewhat darker. paludosa hasn't the grooves velenovsky has the groove but definitly not the color rosea and xerampelina has a reddish stem emetica hasn't the grooves but emetica var. emetica has some!!! (marei has also no grooves at the cap) i think we should let it be and say: emetica is the best guess! the colors can variate : from sunlight,ground-nutritions, genes,or humidity - conditions.!!

Iwould also doubt the Sickener...judging from the red tone. Sickener starts with an orange-red and becomes bright red in the final state. This looks more like one of the three other (close to this) red Russula.

i think with Russula Emetica have you made a good guess. it schould be a russula (maybe a lactaria but i tend to say russula) , your has grooves at the edge of the cap, also emetica. the color can variate, reasons- nutrition.,ground,sun or bad genes. when i search for name or mushroom-identifications: first i look at my fungi-guide[1] ( if you do fungi seriously you should have a holy book), then when i found something similare, i go to google-image[2] and enter the name. after comparing some different sightings of the one funghi (under the picture stand mostly also suggestion of the names), i decide if i go with the name further to wikipedia [3]. or/and eol [4]. after comparing the visual referenzes, searching through the written features. i suggest. that is a way to get through (but you need at least a basic knowledge of what you research). this way can applied to many spottings. good luck

this should be genus: russula.maybe you find the native species yourself otherwise i will look by from time to time and keep an eye open
