LOCATION The Green River Section, Washington.
ORIG DESCRIPTION* Aseptate, psilate fungal spores ca. 10 x 25 µm overall. Outline narrowly elliptical in a fusiform manner with subpointed ends. Furrow straight and parallel to the length of the spore. The furrow almost completely encircles the spore; the more or less equal halves of the spore remain attached to one end which is very slightly less narrowly rounded. Thickness of the spore wall is ca. 0.5 µm or less, generally ca. 0.25 µm.
COMMENTS* Hypoxylonites fusiformis has a similar shape but the furrow only reaches the ends of the spore along one side. Hypoxylonites armentroutii has an encircling furrow like H. eocenicus but H. eocenicus has a more fusiform outline. Derivation: Named for its occurrence in Eocene strata.
