PLATE 33 
Helminthosporium cyclops 
Mycelium, fructifications, and denuded sporophore of H. cyclops developed on Bei- 
jerinck’s agar and drawn 30 days after inoculation of substratum. X 500. 
Aa.—Conidiophore which, after producing many spores, has proliferated the distal 
^orophoric element Ah hy 3. budding process similar to the proliferation of a conidium. 
The distal sporophoric element has given rise to three spores, Aha-bc. 
B. —Conidiophore, the typical development of which has been replaced after the 
proliferation of two primary conidia Ba-b, by the growth of the latter into sporophoric 
elements, on which were developed numbers of secondary conidia. Baa, Bba, etc., 
respectively. 
C. —Denuded conidiophore. 
D. —Conidiophore bearing three primary conidia, one of which (Da) has grown out 
into a sporophoric process bearing three secondary spores Daa-oc; while another (Dc) 
has given rise directly to a secondary conidium Dca by apical proliferation.
