Summary:
Section Endochromonema. Nolanea strictior is distinctive because of 1) a conic to bell-shaped, dark brown, translucent-striate cap, 2) pallid or white gills when young, 3) a striate, light-colored stem with a length up to 16cm, 4) a mild odor, 5) relatively long spores with average length in a given collection over 10.4 microns, and 6) absent clamp connections, (Largent(1)). Peck named Agaricus strictior, using the comparative masculine of ''strictus''. Saccardo named Entoloma strictius, using ''strictius'' which is the comparative neuter of ''strictus'' (Entoloma being neuter despite its ending, and ''strictius'' being a neuter form despite the ''-us'' ending). Since Nolanea is feminine, it should take the comparative feminine of ''strictus'' which is ''strictior''.

Cap:
2-6cm across, bell-shaped to convex to upturned, "acutely umbonate or at times obscurely umbonate", margin decurved [downcurved] then flat to uplifted; hygrophanous, bicolorous, dark brown to dark gray brown on the disc, medium brown elsewhere, when faded brownish orange everywhere; dull, bald, translucent-striate to the disc, (Largent), 2.5-7cm across, conic or bell-shaped expanding to broadly convex or flat, usually with distinct, sometimes pointed umbo; hygrophanous, watery cinnamon to grayish brown when moist, "paler and often somewhat streaked when dry"; smooth, (Arora)

Flesh:
up to 0.2cm thick near gill attachment, (Largent), thin, fragile, (Arora)

Gills:
narrowly adnexed (almost free), "close, narrow to moderately broad", 0.4-0.5cm broad; pallid to whitish when young, edges colored as faces; edges smooth then eroded, (Largent), adnate to deeply notched, adnexed, or free, broad, fairly close; pallid becoming flesh-colored when old, (Arora)

Stem:
8-16cm x 0.3-0.5cm at top, widening downward to 0.6-0.9cm at base, round in cross-section, hollow; silky white and when old becoming brownish orange; longitudinally striate, basal mycelium abundant, (Largent), 5-15cm x 0.2-0.5(1)cm, "typically long and straight (strict)", equal or widening toward base, "hollow, fragile, splitting easily"; whitish or colored like cap but usually paler; longitudinally striate, base whitish and often downy, (Arora)

Veil:
[absent]

Odor:
not distinct (Largent), mild (Arora)

Taste:
not distinct (Largent)

Microscopic spores:
spores 9.3-15.2 x 6.0-11.4 microns, distinctly angular, 5-6 sided, average length in a given collection 10.4-13.0 microns, average width in a given collection 7.3-9.4 microns; basidia 4-spored, 33.6-44.4 x 12.0-14.2 microns, relatively short and squat; pleurocystidia absent, cheilocystidia absent; stem cuticle a cutis, caulocystidia absent; pigmentation intracellular in outer suprapellis of cap, incrustations absent; clamp connections absent in all parts, (Largent), 9-13 x 6-9 microns, elliptic but angular, (Arora)

Spore deposit:
salmon-pink or pinkish-cinnamon (Arora)

Notes:
Nolanea strictior collections were examined from BC, WA, OR, ID, AK, and CA, (Largent).
