Diphasium alpinum (L.) Rothm. 1944 Plate II., Figs 1-3. Description: spores trilete, laesurae distinct, length 3/4 of spore radius, with lips. Reticulate both distally and proximally. On proximal face contact area unornamented, remaining part reticulate. Lumina of distal reticulum rounded polygonal, 7-11 ju in diameter. Muri 1.5-2 ju wide, and 6-7 yu high. Exine 4-5 ja thick. Spore size: 42-47 Ai (excluded muri). Diphasium complanatum (L.) Rothm. 1944 Plate II., Figs 4-6, Description: spores trilete, laesurae straight, almost reaching the equator, with membraneous lips, 1.5JU wide, 2 u high. Laesura arms about 15 ju. Amb subcircular. Reticulate both distally and proximally. Distal face with a more or less perfect reticulum. Lumina of reticulum irregularly hexagonal in outline. Muri faintly winding. Height of muri 3 ju wide 0.5 yu. Proximal face with tangential^ arranged muri of reticulum running to osilate contact area. Exine 3 u thick. Spore size: 35-37 M. Diphasium issleri (Rouy) J. Holub 1960 Plate III., Figs 1-3. Description: spores trilete, laesurae straight, long, reaching almost the equator, with lips. Amb subcircular. Reticulate both distally and proximally. Distal face with perfect reticulum. Lumina of reticulum 6-8 yu in diameter, regularly hexagonal, muri straight, 1 ju thin, and 3 ja high.Proximal face with a smooth contact area, but around the equator the surface reticulate. Exine 3.5-4ju thick. Spore size: 40-42 il. Diphasium tristachyum (Pursh) Rothm. 1944 Plate III., Figs 4-6. Description: spores trilete, laesurae straight, reaching the equator. Amb circular. Proximal face reticulate, but with a smooth contact area. Distal face also reticulate, lumina of reticulum regularly hexagonal. Muri straight, 1.5yu wide, 6-7 yj high. Exine 3-3.5 JU thick. Spore size: 42-45 ju. Morphogroup II: Hamulate sculpture cernua - morphotype: proximal surface unsculptured, distal surface hamulate; exine in interapical region thicker than in apical region. Lepidotis cernua (L.) Beauv. 1804 Plate IV., Figs 1-4. Description: trilete, tricrassate spores. Laesurae straight, simple, length 3/4 of spore radius. Amb rounded triangular, with strongly convex sides. Proximal face smooth, distal face hamulate: ornamented by more or less developed anastomosing rugulae up to 2-3 yu across. Exine 1.5 ju thick apically, and 5ju wide interapically. Spore size: 32-38ju. inundata - morphotype: proximal surface ornamented with granulae or Verrucae; laesurae often surrounded by a margo. Distal surface hamulate. Lepidotis inundata (L.) C. Börner 1912 Plate IV., Figs 5-9. Description: spores trilete, laesurae reaching or almost reaching the equator, often surrounded by a disting margo, which 2-4 ju wide, 1-2 ju high. Proximal surface sculptured by granulae or Verrucae. Distal surface hamulate, consisting of irregularly winding, densely spaced low rugulae,Exine 4-5 yu thick at apices, 5-7 M thick at sides (slightly tricrassate). Amb rounded triangular. Spore size: 62-66 yu.
