Description (from Filipjev and Schuurmans Stekhoven, 1941)
    Head shaped like a flattened cap, only slightly offset.  Spear slender without basal swellings, Oesophagus with oval median bulb, distinctly off set from the anterior portion of the oesophagus.  Oesophageal glands filling up the posterior club-shaped oesophageal portion.  Outlet of the ventral glands at the under side of the lumen of the widening of the median bulb, that of the dorsal side superior to it.  Nerve ring crossing the posterior oesophageal portion slightly back from the bulb, at a level with the excretory pore.  Ovary single outstretched, postvulvar uterine sac present.  Eggs measuring 41-77(54) X 12-23(19) um.
    Male with rather long spicules, more than half as long as the tail, gradually tapering from the swollen proximal end, which is not distinctly offset, to the pointed tip.  Gubernaculum 1/3 as long as the spicula.  The male is in the possession of two praeanal subventral and three postanal pairs of papillae of which two subventral and one subdorsal.
    Occurs in the roots of grasses in the Eastmark of Germany, in Rumania, the Bukowina, as well as in England, St. Albans and Denmark.
    Steiner has found it on diseased Arachis hypogaea, Peanut, in Transvaal, South Africa, Chitwood (1931) on healthy and diseased wild strawberries in the United States (Washington) and on potatoes (Solanum tuberosum) of Denmark.  It occurs further in Narcissus sp. Hort. vars. Pearl Queen and Sir Ernest Shackleton and on Zanthium sp. cocklebur, U.S.A.
