Slightly ascendant or subhorizontal, emarginate, (1.5) 2-3 mm broad, pale beige for a long time, only ochraceous in the oldest stages.
Stipe
(8) 20-35 (40) × (2) 3-5 mm, bulbous marginate, up to 9 (10) mm in the bulb, whitish or pale beige.
Context
White.
Smell
Very slightly honey-like or with a complex herbaceous component.
Spores
(6.5) 7-9 (10) × (4.5) 5-5.5 (6) µm, ellipsoid or slightly reniform, sometimes with a tendency toward subcylindrical, quite pale under the microscope, containing a conspicuous oil drop.
Basidia
Clavate, 4-spored, 25-30 (35) × 8-10 µm, filled with an oily solution.
Hymenial cystidia
Absent
Marginal cells
Variable in size, clavate, (20) 25-40 (50) × 8-12 (15) µm.
