198 NEW SUGARCANE DISEASES 



noted that several species described as Phomopsis are inultiloeular 

 stromatic*, though Diedicke, who has most fully studied the 

 genus, places it amongst the simple forms, and does not seem to 

 include any species with a multilocular stroma. Another genus 

 which may be compared is Endotliiella Sacc, where the bodies 

 described as filiform basidia or pseudo-paraphyses are probably 

 scolecospores.

As this fungus is possibly the lower stage of a Pyrenomycete, 

 attempts were made to obtain an ascigerous stage in culture on 

 organic media. The following w^ere tried :— Potato, carrot, onion, 

 plantain, Colocasia corm, fruit of Carica Pajiaya, fruit of 

 P.sidii(.m Guajava, boiled rice, bread paste and sugarcane fith. 

 The last medium was the only one, besides nutrient agar, in 

 which pycnidial stromata were developed and none gave rise to
