How to distinguish between Lepista nuda and L. sordida

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

NUDA: not very distinctive, rather delicate, weakly flower like when fresh, slightly unpleasant when crushed.
SORDIDA: weak, often with aromatic component, sometimes more or less cyanidic or slightly rancid.
Is it sordida the flour-fungoid smell and nuda the aromatic ???

(6.2) 6.5 - 7.1 (7.5) × (3.8) 4.2 - 4.9 (5)
Q = (1.3) 1.4 - 1.6 (1.7) ; N = 22

The size is within the range of both, but admittingly in the median of nuda and higher end of sordida: cap 75mm across; height 42mm; stipe: 9mm; lamella 6.5mm wide.

I think you are right with L. sordida. It's always hard with a single fruitbody, but the stem diameter is a better fit, along with the other characters. All of the L nuda I've seen has been much more robust. The only L. sordida I've found was noticeably smaller, so much so that I first thought it was Laccaria amethystina.

Thank you Adam - I am considering the smell as a good character too. The Maltese sordida are always a bit more robust than the norm. but maintaining the brownish tones of the pileus in wet conditions.
