PROTEOMVXA 



8 9 



Myxoidea. Flagella 1-3 ; zoospores separating at once. 



1. Zoosporeae. Brood -cells escaping as flagellulae, even if they 



become amoeboid later. Cilicphrys Cienk. ; Pseudospora Cienk. 

 (Fig. 29). 



2. Azoosporeae. Cells never flagellate. Protomyxa Haeckel ; Plasmo- 



diopkora Woronin ; Vampyrella Cienk. ; Serumsporidium L. Pfeiffer. 

 Catallacta. Brood-cells of cyst on liberation adhering at the centre to 



form a spherical colony, multiflagellate ; afterwards separating, and 

 becoming amoeboid. Magosphaera Haeckel (marine). 1 



Plasmodiopliora infests the roots of Crucifers, causing the 

 disease known as " Hanburies," or " fingers and toes," in turnips, 

 etc. Serumsporidium dwells in the body cavity of small Crustacea. 



Fig. 29. Pseudospora lindstedtii. 1, 2, Flagellate zoospores : 3, young amoebula, 

 with two contractile vacuoles, one being reconstituted by three minute formative 

 vacuoles ; 4, 5, an amoebula migrating to a fungus hypha through the wall of 

 which it has sent a long pseudopodium ; 6, amoebula fall-grown ; 7, 8, mature 

 cells rounded off, protruding a flagellum, before encysting ; 9, young sporocyst : 

 10, the nucleus has divided into a brood of eight; 11-14, stages of formation of 

 zoospores, cv, Contractile vacuole ; e, mass of faecal granules ; fl, flagellum ; n. 

 nucleus, x about *$M*. 



Many of this group were described by Cienkowsky under the 

 name of " Monadineae " (in Arch. Mikr. Anat. i. 18G5, p. 203). 

 Zopf has added more than anyone else since then to our know- 

 ledge. He monographed them under Cienkowsky's name, as a 

 subordinate group of the Myxomycetes, " Pilzthiere oder Settle/ m- 

 pilze" in Schenk's Handb. d. Bot vol. iii. pt. ii. (1887). To 

 Lankester {Encyel. Brit, reprint 1891) we owe the name here 

 adopted. Zopf has successfully pursued their study in recent 



1 Most of Haeckel's Monera, described as non-nucleate, belong here. Several 

 have been proved to be nucleate, and to be rightly placed here ; and all require 

 renewed study.
