Observation 276927: Mycena (Pers.) Roussel

Notes:
Appearance of yellow margination on gill edges more likely from dessication/decay than a diagnostic trait. Odor something between grassy and bleachy, but overall mild.

Lamellar edge sterile with long, finger-like/flexuous, narrowly lageniform cheilocystidia.

Spores inamyloid, 1-guttulate, broadly ellipsoid with prominent hilar appendage. spores seen in older material are more varied (see micrograph), with some appearing almost angular. initial measurements taken from fresh spore print directly onto slide.

Q = (1.2) 1.4 – 1.66 (1.7) ; N = 30
Me = 9.8 × 6.3 µm ; Qe = 1.6
