Original Description
Kugel dünnwandig, Maschen fast regelmässig 5- bis 6-eckig, wenig ungleich, 0,010 bis 0,016 mm. breit, mit dünnen, gleichbreiten (nicht deutlich eckig verdickten), (0,001 bis 0,0015 mm. breiten) Zwischenbalken. In allen Maschenecken feine, nadelförmige Nebenstacheln, ungefähr so lang wie der Radius (0,037 bis 0,045 mm.).
[Sphere thin-walled, meshes almost regular with 5-6 angles, not so much of different sizes (10-16µm), with thin bars (1-1.5µm) of uniform size (not clearly thickened at angles). On all node frames, needle-shaped secondary spines approximately as long as the radius (37-45µm). (In German. Translated by J.P.C.)]

Shell diameter 81 to 83µm. Distinguishing characters (rw): Sieht der Leptosphaera arachnoides sehr ähnlich, scheint aber der feinen arachnoidalen Hülle vollständig zu entbehren.
[Very close to Leptosphaera arachnoides, but completely lacking a fine arachnoidal shell.]
