CHYTRIDIALES 447 



globule, discharged through a 40 \i broad opening in a mass surrounded 

 for a time by the gelatinized wall of the sporangium ; resting spore with 

 a smooth, thick wall and large refractive eccentric globule, bearing a 

 somewhat apophysate rhizoidal system within the substratum and a 

 bundle of rhizoids at the apex, at germination producing zoospores, 

 5.5 [j. in diameter, endogenously as in the sporangium. 

 Pine pollen, in sea water and in fresh- water deposits, (Venice) Italy. 



IMPERFECTLY KNOWN SPECIES OF RHIZOPHLYCTIS 

 ? RHIZOPHLYCTIS PALMELLACEARUM B. Schroder 



Biol. Centralbl., 18: 534. 1898 



Sporangia ovoid, 5-7 \i long by 3-5 \i in diameter, with a yellowish 

 smooth wall; rhizoids profusely dichotomously branched; all other 

 characteristics unknown. 



Parasitic in cells of a palmellaceous green alga, Germany. 



Said by Schroder to be near Rhizidium braunii in its general features 

 but much smaller. 



? Rhizophlyctis spp. Sparrow 

 Rev. Soc. Cubana Bot., 9: 37, pi. 1, figs. A-I. 1952 



(1) Thallus consisting of a saccate plexus of lobulations, up to 320 \i 

 in length by 96 u. in greatest diameter, from which at several places a 

 very coarse, extensive branched rhizoidal system emerges ; at maturity, 

 up to six broad sessile discharge papillae formed; contents deep orange, 

 cleaved into segments, approximately 5 \x in diameter; no zoospore 

 discharge induced. (2) Thallus at maturity intricately lobed resembling 

 a group of monocentric individuals, except that one segment has become 

 walled off thus making the thallus polycentric ; contents orange. 



From soil, Cuba. 



A fungus isolated from soil samples, collected by T. Schreuders near 

 Batavia, Java, showed a similar somewhat lobulate reproductive ru- 

 diment. Whether all three are variations of the monocentric type, or 

 represent a new group of organisms is at present problematical.
