100 ZYGNEMATACEAE United States: Wisconsin (Prescott Coll.). Sweden; Finland; Holland; Czechoslovakia. 45. MouGEOTiA ANGOLENSis W. & G. S. Wcst 1 897. Jour. Bot. 35, P-39- Vegetative cells 25-29 /x x 100-145 /x; chromatophores with 4-6 very small pyrenoids irregularly disposed; conjugation scalariform; zygospores in the conjugating tubes, short-cylindric with concave sides, 19-21 XVI, Fig. 16.) /x in diameter; wall smooth; gametangia slightly curved. (PI. Africa, Angola. West's drawing of the spore may be misleading. The polar ends should be visualized as circular. 46. MouGEOTiA LAETEviRENS (Braun) Wittrock 1877. Wittrock and Nordstedt Algae Exsiccatae, No. 58. Bot. Notiser 1877. p. 23. Vegetative cells 35-40 /x x 65-350^1; chromatophores with numerous scattered pyrenoids; conjugating cells geniculate; conjugation scalariform; zygospores in the conjugating tubes; outer wall short-cylindric, /Li 36-47 X 45-72;"., with concave sides; spore wall yellow-brown, smooth; aplanospores ovoid or obliquely ovoid. Spores quite variable in form. (Pl.XVI, Figs.9-11.) Florida. United States: Wisconsin and Indiana; eastward to Massachusetts and Europe; South America; southern Siberia; India; China; Australia. 47. MouGEOTiA ACADiANA Transeau 1934. Trans. Amer. Micros. Soc. 53, p. 224. Vegetative cells 43-54/^ x 100-400 û,; chromatophores with many scattered pyrenoids; conjugating cells geniculate; conjugation scalariform; zygospores in the greatly enlarged conjugating tubes, cylindric- ovoid, usually with concave sides, ends convex, 51-70 /x x 57-78 m; spore wall yellow, thick, smooth. Similar to M. laetevirens but larger in all dimensions. United States: Mississippi and Florida. Latvia (Skuja); Czechoslovakia (Czurda). Some of the records for M. laetevirens probably belong to this larger species which it closely resembles. 48. MouGEOTiA oPELOusENSis Taft 1 944. OIlio Jour. Set. 44, p. 238. Vegetative cells 25-28 /x x 1 50-340 /x; chromatophores with 6-12 pyrenoids in a single row; conjugation scalariform; zygospores short-
MOUGEOTIA loi cylindric, with concave ends and sides, formed in the tubes, 55-64 /^ x 30-34 m; spore wall yellow punctate; punctations about .8 /a in diameter and evenly spaced over the entire wall. (PI. XVI, Figs. 13-15.) United States: Louisiana, Opelousas, 1938. 49. MouGEOTiA DEPRESSA (Hassall) Wittrock 1880. SJândinaviens Vaxter. 4, p. 23. Vegetative cells 7-12/A x 35-144JU,; conjugation scalariform and lat- eral; zygospores in the conjugating tubes, compressed-ellipsoid with the longer axis parallel to the filaments, 28-32 /x x 12-14 /x; spore wall brown, punctate. (PI. XVII, Fig. i.) United States: Mississippi; Florida. British Isles; Germany; Sweden; Luxemburg; Switzerland. When the spores are immature there is a distinct pectic layer on the sporangium wall. 50. MouGEOTiA ovALis (Hassall) Nordstedt 1886. Bot. Notiser 1886. p. 136. Vegetative cells ii-i4iU, x iio-140/u; conjugation scalariform; zygospores in the conjugating tubes, compressed-ovoid to subglobose, 29-38 /x x 26-36 /x; spore wall finely scrobiculate, brown. (PI. XVII, Figs. 2-3.) British Isles; Italy; Germany; Switzerland. It seems probable that specimens will be found with a pectic layer on the sporangium walls. 51. MouGEOTiA PECTosA Transeau 1934. Trans. Amer. Micros. Soc. 53, p. 220, Figs. 53-54. Vegetative cells 14.5-19,", x i:io-iôix\ chromatophores with 4-8 pyrenoids in a single row; conjugation scalariform, but less frequent than reproduction by aplanospores; zygospores in the conjugating tubes enclosed in a 5-10 /a thick pectic sporangium wall, compressed-globose, 26-29 /x ^ 20-22 A*; spore wall colorless, smooth; aplanospores globose to compressed-globose, formed partly within or largely outside the mother cells, 18-21 /x in diameter, when formed outside the mother cell covered with a pectic layer. Spores may not have been fully mature. (PI. XVII, Figs. 4-6.) United States: Florida (Tiflfany Coll.). 52. MouGEOTiA GELATiNosA Wittrock 1 889. Wittfock and Nord- stedt Algae Exsiccatae, No. 957. Vegetative cells i2-i8f(. x 1 20-1 80 /x; chromatophores with 3-6 pyrenoids in a single row; conjugation scalariform; zygospores in the conjugating tubes, compressed-ovoid, 38-47 ju- x 28-39 /x, ^^^ including the
