Observation 21685: Bolbitius coprophilus (Peck) Hongo

When: 2009-06-04

Collection location: New Port Richey, Florida, USA [Click for map]

Who: Erica Urbanovitch (erica)

No specimen available

Growing in manure pile, tallest about 5", cap pink and olive green

Spores rust brown

Photos taken about 6pm Thursday, all examples completely gone with no trace in the next morning. (Surrounding mushrooms intact, maybe an animal found this species good to eat?) I was hoping to get a picture with caps fully open, oh well. I’m drying the specimen shown in the last photo, glad I collected it when I did.

Recognized by sight: It’s not Bolbitius vitellinus, but it looks a lot more like a Bolbitius to me than a Coprinopsis sp.. I have never seen a young Coprinopsis with yellow or pink tones like that. Yes Coprinus gets pink, but that’s only in ‘age’.

Check if it is viscid

Before you go further, you need to make sure the cap surface is viscid at least. If it isn’t viscid, then it isn’t a Bolbitius. At least there are Bolbitius that are colorful, not like other similar genera, like Conocybe, Pholiotina and such, which are all brown. There is the Bolbitius psittacinus, which has a fairly redish cap, and a yellowish stipe. But this one is only known from the Czech rep., and was found on wood chips, not on dung piles.

Definitely a Bolbitius species.

These really look nothing like any Bolbitius specie to me.

That pink staining colour is indicative of Coprinus and Coprinopsis.

Coprinus are defined by floccose scales, and a thin, soft string in the core of the stipe which can be easily removed. So I am going to rule out Coprinus.
Maybe cross section the stipe just for kicks..

Don’t know what they are immediately. See if you can get a dried specimen for these.

Image 45709 -I don’t know if it’s the same species as the rest, but it was growing amongst them, and it shows the sacrifices we make to take these pics…
I HATE spiders… ugh
Spore print coming soon
