Habitat: in sandy soil, ~1/4 mile inland from the shore, growing in thick patches of dune grass (Ammophila sp. ?) beneath Shore Pine (Pinus contorta var. contorta) and Sitka Spruce (Picea sitchensis)
Habit: scattered to gregarious
Odor: slightly sweet, fragrant, distinctly un-raphanoid
Taste: … can’t remember (sava?)
Pileus: 4-8.5cm in diameter, white to buff brown, lighter at margin, broadly convex to nearly planar in age, context white and unchanging, inrolled when young, subviscid, exceeding lamellae at all stages of development.
Lamellae: close, sinuate w/ a slight unpigmented decurrent tooth, white to pale pinkish brown to light earth brown at maturity, lamellulae present (2 series), edges lined with fine white encrustations (cheilocystidia), ventricose, ~1cm broad at thickest portion
Stipe: 5.5-8.5 cm in length, equal above (8-12mm thick) with gradually enlarged base (up to 20mm), pearly white discoloring light brown to earth brown with age/handling, stuffed when young to hollow in age, surface dry, sparsely fibrillose, texture fibrous to slightly twisted-fibrous, fissuring longitudinally to reveal a pallid background, apex persistently white, dandruffy to mealy (caulocystidia).
Pileipellis: an ixolattice of long, slender (2-4μm wide), septate, clamped hyphae.
Cystidia: Pleurocystidia absent. Cheilocystidia abundant, cylindro-clavate, up to 100μm in length, often in large bouquet-like clusters, varying in thickness throughout (3-5μm), enlared at apex (5-9μm), infrequently enlarged/swollen below. Caulocystidia present, similarly clustered and shaped.
Spores: Broadly elliptical to amygdaliform, some slighty citriniform (having a distinct nodule opposite the apiculus), inequilateral in profile, asperulate, most containing one large droplet, non-dextrinoid
