Assorted unidentified gilled fungi from my rambles of the last day or so. Please post identifications in comments section!
Gomphidius?
This one is nearly two feet across.
Mycena? Tiny mushrooms sprouting from a stump.

1. Definitely a Russula
2. How about Laetioporus sulphureus ‘chicken of the woods’ – I’m assuming it had pores and not gills
3. Hygrocybe but like the Russula – which species?
Thank you for these!
The first appears to be a Russula, though the single photo doesn’t allow me to say that with absolute confidence. The second is Bondarzewia berkeleyi (Berkeley’s Polypore)*; the third, without seeing the gills closely, I cannot identify to genus, but I can say it is neither a Hygrocybe nor a Mycena. Xeromphalina is a strong possibility.

Fabulous! Thank you.
Do you have any recommendations about good guides to the fungi of the SE (most of the ones on the market are NE oriented)?
