Amanita umbrinolutea, also known as the '''umber-zoned ringless Amanita''', is a [[species]] of the [[genus]] [[Amanita]].

== Description ==

The [[Cap (mycology)|cap]] of ''Amanita umbrinolutea'' is usually free of [[Volva (mycology)|volval]] remnants, 45 – 90&nbsp;mm wide, at first conico-paraboloid, then somewhat campanulate to [[Convex geometry|convex]] and finally [[Planar geometry|planar]], [[umbonate]], with a strongly striate margin (margins occupying around 25 - 35% of the whole cap's radius). The [[cap (mycology)|cap]] has a distinctive pattern of color, often dark in the center, then pale, then dark over the inner edges of the [[Lamella (mycology)|lamellae]] and on the ridges between the marginal striations and at other times pallid in the center, but also strongly [[zonate]]; intensity of pigmentation is variable, with the center ranging from umber to grayish umber-brown to beige or pale grayish brown even within a single collection. The [[gill (mycology)|gills]] are free, crowded, off-white to sordid pale cream in mass, and up to 6&nbsp;mm (0.6&nbsp;cm) broad; the short gills are [[truncate]], of varying length, scattered and unevenly distributed.<ref name=Amanitaceae>{{cite web | url = http://www.amanitaceae.org/?Amanita%20umbrinolutea| title = ''Amanita umbrinolutea''|work=Amanitaceae.org |accessdate=2016-08-27}}</ref>

The stem is 115 - 185 × 6 – 11&nbsp;mm, pale cream to pale [[beige]] or isabella color or pale grayish brown, with a faint appressed zigzag girdles of fibrils, with a fleshy [[Membrane (biology)|membranous]] sack-like volva at the base. The 30 – 40&nbsp;mm high volva is attached to the bottom 5&nbsp;mm or so of the stipe. The spores measure 10.5-13.4 × 9.5-12.5 (1.05-1.34 x 0.95-1.25&nbsp;cm) [[μm]] and are [[Globose|subglobose]] (infrequently either globose or broadly [[ellipsoid]]) and [[inamyloid]]. Clamps are absent from the bases of [[basidia]]. ''Amanita umbrinolutea'' is widely distributed in [[Europe]]. The specimens different researchers and scientists have examined has all been found in association with [[conifers]] (including [[pine]] and [[spruce]]); and its range extends eastward at least to around northwestern [[Pakistan]] and [[northern India]].<ref name="Amanitaceae"/>
