Tahquamenon Falls State Park, and near Marquette, in the Upper

spectabilis by its glabrous pileus and in not being associated with larch.
F. sinuspaulianus does not have a gelatinous veil.

Illus. Pls. 40-41.
Pileus 4-10 cm broad, obtuse to convex, becoming flattened with
or without an obtuse umbo; surface viscid to slimy beneath the remains
of the veil which often form rather large grayish brown patches, scales,
or streaks composed of soft tissue or tomentum; veil remnants finally
rich red ("Morocco-red") throughout but finally fading to yellowish or
brownish, color beneath the veil also soon some shade of red to rose.
Context yellow, becoming deeper yellow by maturity, not changing to
blue when exposed but slowly to pinkish and then brown, odor penetrating and disagreeable or somewhat aromatic, taste astringent.
Tubes 6-12 mm long, adnate to decurrent, pale yellow, usually
changing to pinkish when injured, dull yellowish brown in age; pores
concolorous with sides, angular, obscurely radiating, elongated, about 1
mm wide or more, often compound, dotted with small dark points when
old and dry.
Stipe subcylindric, 4-10 cm long, 10-15 mm thick, solid, pale
yellow throughout when young, in age olive in the base and chrome to
ochraceous in the midportion, rarely becoming hollow, yellow above the
annulus, sheathed with the remnants of the red veil and the veil leaving
a gelatinous annulus; veil colored like the pileus, sheathing the stipe from
base to annulus, soon fading to vinaceous-gray, yellowish beneath,
duplex, floccose to the interior (towards the stipe) and gelatinous on
outer (under) side, leaving patches on the stipe in age, these more or
less evanescent in age.
