intro Limacella olivaceobrunnea is known from a single island in Japan.  From its original description, it is very likely to be correctly placed in Limacella.
cap The cap is 50 - 60 mm wide, olivaceous brown, darker yellowish brown in its center, glutinous, covered with brown granular squamules (especially in the center), and somewhat radially veined.  It is convex at first, then plane, and finally shallowly depressed.  It develops a low, broad, obtuse umbo.  The cap's flesh is white, rather thin, and soft.  The colored surface layer of the cap [probably consisting of the slime, the hyphae that support the slime and some of the upper part of the cap's flesh] can be peeled away.
gills The gills are free, "close then subdistant," white, 4 - 5 mm broad, ventricose, and have a smooth edge.
stem The viscid stem of this species is about 70 × 9.5 - 12.5 mm and is paler than the cap.  It is white in the topmost portion and pale olivaceous brown below and it has a subclavate base.  The stem is solid and any ring that may be apparent during development of the mushroom is evanescent.
odor/taste Limacell olivaceobrunnea is said to have only a slight odor and to taste mild.
spores The spores of this species measure 6.5 - 7.5 × 5.5 - 7.0 μm and are broadly ellipsoid or subglobose, minutely punctate, and inamyloid.  Clamps are present at the bases of basidia.
discussion In the original description, this species is said to have been found "on the ground in shady, moist forest."  The only known occurrence was in the Bonin Islands (Japan).
