6. MouGEOTiA ELLiPsoiDEA (W. & G. S. Wcst) Czurda 1932. Siiss- 



w as ser flora Mitteleuropa. 9, p. 66. 



Vegetative cells 9.5-1 1. 5 /x in diameter; conjugation scalariform; 

 zygospores formed wholly in the conjugating tube, ellipsoid, 16-26 ij. x 

 22-28 ju.; spore wall smooth, brown at maturity. (PI. XIII, Fig. 14.) 



Burma; Austria. 



7. MouGEOTiA vicTORiENSis G. S. Wcst 1909. Jour. Lifjfi. Soc. of 



London Bot. 39, p. 51. 



Vegetative cells ii-i2At x 1 00-160^1; chromatophores with 2-7 

 (usually 5-6), pyrenoids in a single, more or less irregular row; con- 

 jugation scalariform; zygospores formed wholly in the conjugating 

 tube, globose, 2 1-24 /x in diameter; spore wall smooth. Surrounding the 

 sporangium a layer of pectic material develops which extends even 

 beyond the outer sides of the gametangia, 60-63^1 in diameter. (PI. XIII, 

 Fig. 18.) 



Australia, Victoria. 



8. MouGEOTiA RECURVA (Hassall) de Toni 1889. Sylloge Al- 



garum. 1, p. 714. 



Vegetative cells 12-18/^ x 50-1 80 /a; chromatophores with 4-8 pyre- 

 noids; conjugation scalariform; zygospores formed wholly in the con- 

 jugating tube, globose, 22-33 /a ^^ diameter; spore wall brown, smooth; 

 aplanospores globose, 24-30^1 in diameter, at the bends in geniculate 

 cells, or cylindric-ovoid, 14-18/i x 28-34 /i., in straight cells. (PI. XIII, 



Fig- I3-) 



United States: Michigan; Florida. 



Maritime Provinces of Canada; British Isles; Germany; Australia; 

 Puerto Rico; South America; northern India. 



In the collection from Florida the spores, although mature, were highly 

 variable in dimensions.

Fig- 3- 



Vegetative cells 15-17 /^ x 1 80-240 ;u, enveloped by a sheath 6-8 /a 

 thick; chromatophore platelike, with 4-10 pyrenoids in a row; conjuga- 

 tion lateral and scalariform; zygospores formed in the enlarged con- 

 jugating tube, which also develops an outer pectic layer; in lateral 

 conjugation elUpsoid or rarely reniform, 26-32 ju. x 30-38 /i.; in scalar- 

 iform conjugation globose or dolioform, 3 1-33 m x 35-37 /x; spore wall 

 brown, smooth. (PI. XIII, Figs. 15-17.) 



India, Periyar, on wet rock slopes.
