Observation 62191: Chroogomphus (Singer) O.K. Mill.

When: 2011-01-11

Collection location: Pine Trail Ranch, Davis, California, USA [Click for map]

Who: Byrain

No specimen available

Growing in grass under an unidentified bush right in the center of a fruiting of Helvella lacunosa, the observation for them is here – http://mushroomobserver.org/62111?q=3NeY Pine was also close by and the spore print color is rather faint and ambiguous, some sort of light yellow/green. I will try leaving it longer, but I am not sure if that will help.

Recognized by sight: I am unfamiliar with Gomphidiaceae of NA but the key says so.

Recognized by sight: color and size not so important for ID. As far as I know, only two species occur in CA, vinicolor and ochraceus. The best way to tell them apart is under the scope: vinicolor has thick-walled cystidia and ochraceus has thin-walled.

Occur in CA
But C. pseudovinicolor is a very rare entity with a much larger stipe and fruitbody and bands of pigmented tissue about the stipe.

I see olive and darkening grey, so that fits more than what I thought when I read the obs.
I have found Chroogomphus vinicolor twice now and the second find looked nothing like the first if you were comparing the caps’ colors.

The key for Chroogomphus in mushrooms demystified says the stalk should be at least 2 cm thick, this one has a 1 cm thick stem. While the other Chroogomphus species seem to have darker prints, while this one dropped a rather light color.

a light-ish colored spore. Chroogomphus has black spores, no?

oops, I should have read further. sorry! Green is the color.
