Observation 55951: Lyophyllum semitale (Fr.) Kühner
When: 2010-09-20
No herbarium specimen

Notes: This one has me stumped. It does not look like postings of this species on MO.
It does match Kuo’s description at mushroomexpert.com and fits the photo at Mycoquebec.org.

I do not have the collection as I was traveling. I think you are correct. It matches this photo quite well. http://www.mycoquebec.org/... semitale/ Lyophylle des sentiers&tag=Lyophyllum semitale&gro=26

If you still have them, how do they look now?
I was thinking of Lyophyllum semitale, with a strong farinaceous (a bit rancid) smell/taste. It should be blackening (but it’s a rather slow process).

Melanoleuca cognata has crowded lamellae, not such a dark pileus, and a very characteristic smell.
This looks much more like a Lyophyllum. Are the fruitbodies firm – try tapping them.

could at least confirm or rule out Entoloma..

Funny…

The Entoloma/Lyophyllum/Lepista problem rears it’s ugly head again.

tells me that this is no Melanoleuca. Rather Entoloma, or Lyophyllum, or maybe Lepista.
