Dear friends, I need your advice on this nice Leucoagaricus I found in a park under Pinus halapensis (and Eucalyptus) on calcareous soil. A rather robust basidiocarp, white/beige with a rather pale brown or coffee-milk pileus which in old specimens cracks into large scales. Spores dextrinoid, almond-ovate with rounded end and an indistinct or absent germ. pore (not sure about it to be honest, but seems not evident). The cheilocystidia are quite narrow and many are subcapitate or ventricose. The pilleipellis was also examined and terminal hyphae observed (see images). I am undecided about a few species such as L. leucothites? (must be white and has larger cheilocystidia!) L. wichanskyi (germ pore should be absent?) or L. cinerascens (cheilos are wide?) but I can't make up my mind.
Pileus up to 7cm wide
Spores dextrinoid 8.5 − 12.9 x 5.3 − 7.1 µm (10 x 6 um) / Q-factor: 1.4-2.0 (1.6)
Cheilocystidia subcapitate or ventricose 31.1 − 55.0 µm x 6.2 − 11.4 µm ( 42.28 9.14 µm)
