Sub-order III. — Comomycetes.

 abundant, conspicuous, often large, surrounded by a perithecium 

 or naked, terminating in conspicuous threads. Threads often 

 arising from a creeping mycelium. Peridium — perithecium — 

 when present very delicate and evanescent. In this suborder will 

 be found the numerous parasitic species, which affect the living 

 organs of plants and cause such mischief to corn and other crops 

 by exhausting the energies of the mother plant, and thus prevent- 

 ing the full development of the seed &c. 



Tribe Sph^eonemei. 

 Perithecium more or less distinct. 



Phoma, Fries. 

 A minute fungus, forming pustules on wood, leaves, &c. 

 Perithecium subglobose or punctiform, discharging minute simple 

 spores by a small orifice at the apex. 



P. rosarum, Dur. et Mont., on rose aculei, Bulimba, Brisbane 

 Eiver (Mrs. C. Coxen). 



Toeulacei. 

 Perithecium altogether wanting, spores compound, moniliform 

 or raising from repeated division — rarely reduced to a single cell.
