the shape of the cap

seems not a distinctive feature to me, but accidentally. There are many Conocybe species on dung, even with this bright coloration there is more then one. I don’t think that Conocybe is determinable without microscopical deatils even for the specialists.

hmmmmm, does this one have giant spores?

Thanks Darvin & Erin,

I see this every year in our cow fields and Conocybe sp. is as far as I’ve gotten with it. It does have brown spores, If I get around to it I’ll post a picture of a spore print.

Noah, nice find! I’ve never seen this Conocybe before! The cap has a very distinct shape compared with the more common conical species of the genus. I like the striations on the stipe as well, especially apparent near the top where the gills meet.

Daniel, these really don’t resemble any dung dwelling Psilocybe at all. All of the colours are off- far too yellow. The gills look white, but they will produce rusty spores. The dusty white appearance of the stipe is not spores, it is just the texture of the stipe. That texture is not seen on the lower half of the stipe in the two larger specimens that were picked because that is were they were handled.

Similar to Psilocybe coprophila

but probably not a match. Problem is the gill coloration, and probable spore color (looks white to off-white to me, visible on stipe near gills). Growing on dung suggests coprophila, but gills too light-colored, and spore-print doesn’t look violet brown. One of those instances where a spore print would help lots.
