The general appearance is that of PeniciUium, but in 

 the latter the radiating chains of gonidia are naked 

 or not enclosed in sporangia. The genus Pipfo- 

 cephalis, which has not yet been met with in Britain, 

 resembles the present in the form and arrangement 

 of the sporangia, but it is distinguished by the 

 repeatedly forked sporangiophores. 



Syncephalis fasciculata, Van Tiegh. (figs. 22, 23). 



Sporangiferous hyphse erect, fasciculate, colourless, 

 inflated at the base, and becoming attenuated upwards, 

 terminating in a spherico- depressed, warted vesicle ; 

 sporangia containing only few gonidia, cylindrical, 

 simple or forked, springing from the warts on the 

 apical vesicle ; gonidia cylindrical, truncate at the 

 ends, colourless, 6-7 x 3-3*5 fx.

 Nat. ser. vi. vol. i. p. 130, t. 3, figs. 120—122; Sacc 

 Syll. vii. n. 787. 



Forming minute mould-like patches on damp 

 substances or in water. Kare. 



Sporangiferous hyphse 300-400 /x high, 16-20 ^ 

 thick at the basal swollen portion, and tapering up 

 to 4-6 fi at the apex. 



Fam. 2. Peeoxospgeaceje. 



Hyphse usually branching ; asexual reproduction 

 by zoosporangia, containing zoogonidia that germinate 

 at once, or by gonidia .that germinate by developing 

 a germ-tube ; sexual rejoroduction by oogonia and 

 antheridia.
