FIGURE REFERENCE Elsik WC. 1990. Hypoxylonites and Spirotremesporites, form genera for Eocene to Pleistocene fungal spores bearing a single furrow; Palaeontographica, Abt. B, v. 216, p.137-169.
SPECIES, AUTHORITY H. ramanujamii Elsik 1990a, p. 156, pl. 1, fig. 43.
LOCATION Possibly reworked in the Gulf Coast; Green River section, Washington, USA.
ORIG DESCRIPTION* Aseptate, psilate fungal spores ca. 11-14 x 20-27 µm overall; depth as seen in side view is 10-12 µm. Spore wall ca. 0.5-1 µm. Outline elliptical in top view. The longitudinal furrow is from less than 3/4 to somewhat less than the full length of the spore. The furrow is on a straight to somewhat concave surface; when the spores are compressed in top view, at least one end of the spore tends to fold over one end of the furrow. In side view the outline is reniform; the furrowed side is straight or almost straight, the other is roundly convex.
COMMENTS* Characterized by its shape and length of the furrow. Hypoxylonites tennesseensis is somewhat similar in size but the furrow there is on the raised, convex face of the spore.

Derivation: Named in honor of C.G.K. Ramanujam.

K&J REMARKS Kalgutkar and Jansonius's (2000) diagram represents Elsik's fig. 44a,b, which is more pigmented than the type, and hence shows the furrow more clearly.
