exeuntis maiientibus, sed mox acriter moventibus. Rhizoideo sys- 

 temate uno loco in radice sporangii plerumque oriente, crasso (prime 

 axi 2-7 ih diametro), niaxime ramose, 100-600/x longe. Spora per- 

 durante aurantiaca aut auruginosa, plerumque sphaerica, 18-24/it, 

 oblonga, 10-13/a x 15-18/x, elengata et truncata, 10-22/x cum magnis 

 centricis globulis numere uno ad tres 8-1 5/x diametro atque strato 

 parietali globorum minorum ; pariete aeruginoso 1.5-2/a crasso, 

 levi ; spora perdurante per porum parietis in zoosperangium parie- 

 tibus tenuissimis praeditum germinata. 



Saprophytic in dead leaves of Elodea canadense, Eriocaulon 

 septangulare, and Vallisneria sp. State Park Lake, Bastrop, Texas. 



Because of its brilliant golden-red color, this is one of the most 

 striking rhizidiacous species I have ever observed. Whether or 

 not it is identical to the similarly-colored species, E. aiirantia, 

 described by Miss Domjan^ in Hungary, however, is open to ques- 

 tion. Her description and figures are meager, and the account of 

 proliferating zoosporangia suggests the presence of Cladochytrium 

 rcplicatimi instead of a monocentric rhizidiacous chytrid. The 

 zoospores of our species are smaller than these of E. aurantia and 

 form a globular mass at the mouth of the exit tube instead of 

 emerging singly and swimming directly away. 



Another known chytrid of considerable interest discovered in 

 the Texas collections is Nowakozvskiella ramosmn. This species 

 was found by Butler" in 1907 in rotting wheat stems in India and 

 has not been reported as such since that time. However, the resting 

 spores of N. endogena described by Miss Demjan in leaves of 

 Typha doubtless relate to this species. I found A'^. ramosum in rot- 

 ting oat leaves in a water trough en the Karling estate near Austin, 

 Texas, and have isolated it in pure culture en synthetic media. This 

 species is particularly interesting because of the marked prolifera- 

 tion of cells in relation to resting spore formation, the appearance 

 of which strongly suggests zygomycetous sexual reproduction. 

 Ivesting spores were formed in great abundance in our material 

 along with zoosporangia and germinated within 8 to 21 days. In 

 germination they may function as a prosporangium and form a 

 thin-walled zoosporangium en their surface or become transformed
