Observation 6119: Entoloma P. Kumm.

When: 2008-01-14

Collection location: Santa Rosa, Sonoma Co., California, USA [Click for map]

Who: Debbie Drechsler (debdrex)

No specimen available

In a grassy area under live oak. Spores are pink with brown tones. Arora’s key leads me, well, nowhere that I could find a good match. I was interested in the veined gills but don’t know if that’s their normal state. The pileus starts out dark brown as in the first photo and fades to a lighter brown.
1/21/08: No odor. The stipe is much more fragile than any of the Entoloma bloxami I’ve encountered and none of the specimens were blue black or black. Those photographed in situ were the darkest I found. The gills go from a non-descript buff color to pinkish. No blue-grey Also these are pretty small. The largest pileus was 4.2cm across and the smallest was 2cm.
1/24/08: I’ve been combing through Arora’s keys, trying to find something that might match. Seeing Darvin’s recent observation of Entoloma ferruginans makes me wonder if it would be possible that that’s what these are, even though they were odor-free? Habitat is right and they look very much like several of the other observations of this mushroom. Okay, well there are still those veined gills…

Entoloma sp.

With the gills dev. the pinkish tones, these are Entoloma. There are a lot of Entoloma, and very few people seem to be able to put species names on them. I picked up an Entoloma the other day here, which was similar except it had a darker cap and gills, but it also had the intervenose veins you show here.

I’d go with unknown Entoloma here. Unless you want to go through Entolomacae of CA, Largent, and try to figure it out. Only ~250 pages, and ~$200, give it a shot. And while you do that, if you could simplify and summarize, and produce some easy to understand field keys, that would be a help to us. (Well… someone should…)

I find the veined gills typical of Marasmius, though I’ve seen it in many other genera as well.

Well I would definately go with an entaloma… It looks an aweful lot like a very stout nolanea… Well as for veined gills it could be of imporance but I tend to find a corelation between thick gills and some small veins…

I was going to suggest Tricholoma, but then again, are those pinkish tones to the gills? Maybe an Entoloma? Did it smell like anything? If it gets more blue-grey, and the gills more pinkish it might be Entoloma bloxami.
