? Resticularia boodlei F. E. Fritsch 

 Ann. Bot. London, 17: 661, pi. 29, figs. 1-18. 1903 



"Endophytic mycelium (diam. 5-8 \x) with occasional septa; exo- 

 phytic mycelium relatively broad (diam. 1 .5-5 la), much branched, form- 

 ing numerous large thin-walled spores (diam. 12-15 \x), generally in a 

 chain on lateral branches. Infecting hyphae abundant. Endophytic 

 mycelium rarely branched. Zoospores not observed" (Fritsch, loc. cit.). 



In filaments of Tolypothrix sp., Great Britain. 



? Resticularia oedogonii Skvortzow 

 Arch. Protistenk., 51: 432, fig. 14. 1924 



Endobiotic thallus branched, 1-1.7 [a in diameter, several in a host 

 cell, extramatrical thallus very delicate; resting spores from one to two 

 in a host cell, 1 1.5-18.5 [a long by 7.4-1 1.1 \x broad, with a thick smooth 

 colorless wall and a large oil globule nearly filling the lumen. 



In filaments of Oedogonium, Manchuria (northern part). 



Lagenidium closterii de Wildeman 

 Ann. Soc. Beige Micro. (Mem.), 17: 43, pi. 6, figs. 1-5. 1893 

 (Fig. 81 C, p. 1002) 

 Thallus extensive, branched, more or less isodiametric or somewhat 

 expanded and irregular, straight or twisted, about 1.8-2.8 \x in diameter; 

 sporangia of variable length, delimited by narrow septa, discharge tube 

 produced as a lateral outgrowth, which forms a large spherical or sub- 

 spherical structure just beneath the host wall, constricted locally when 

 passing through the wall, more or less prolonged extramatrically, up to 

 20-30 la, cylindrical; zoospores bean-shaped, laterally biflagellate, 5.6- 

 6.3 [jl long by 3.8 la wide, formed in a vesicle at the orifice of the discharge 

 tube, movement hopping or describing a smooth spiral path; plants 

 dioecious, female gametangium much expanded; male gametangium 

 cylindrical, with a prolongation which makes contact with the female 

 gametangium; resting spore spherical, not filling the oogonium, 10-12 fi 

 in diameter, with a thick double wall, the outer surface irregularly
