THE LOWER FUNGI^PHYCOMYCETES 



15. Saccomyces Serbinow (Scripta Hort. Bot. Petrop., 24: 162, 

 1907). 



Erected on a single species, S. dangeardii Serb., found in 

 Euglena in Russia. See also Rhizosiphon Scherffel (1926: 167). 



16. Phlyctidium A. Braun (Monatsber. d. Akad. d. Wiss. 1855). 

 The genus contains several species, all of which occur in algae. 



One of these P. brevipes (Atk.) v. Minden (Fig. 28) was first 



J'iG. 30.- — Diplophlyctis intestina (Schenk) Schroter. (a) Infecting swarm- 

 Bporc. (/)) Young plant, (c) Older plant with subsporangial vesicle, {d) 

 Mature plant with papilla of dehiscence, (e) Sporangium freeing swarmspores. 

 (/) Swarmspores. (fif) Resting sporangium. {After Zopf 1884-) 



described by Atkinson (1909 a) from North America on Spirogyra 

 as Rhizophidium brevipes Atk. Perhaps Physorhizophidium 

 Scherffel (1926: 181) belongs here. 



17. Entophlyctis Fischer (1892: 114). 



The genus contains several species (Fig. 29), all of which occur 

 in algae. A critical study of E. heliomorpha has been made by 

 Karling (1928). 



18. Diplophlyctis Schroter (1892: 78). 



Erected on D. intestina Schroter (Fig. 30), found occurring in 

 dead or dying cells of Cham and Nitella (consult Karling 1928: 

 204).
