Ophiobolus. 



The conidial forms corresponding to the species of Ophiobolus 

 have been very little examined as yet. Mangin (99) says — dubiously 

 however — that Ophiobolus graminis corresponds to Coniothyrium 

 rhizophilum, and Ophiobolus herpotrichus is stated to correspond to 

 Hendersonia herpotricha. 



Saccardo supposes that two different conidial forms, Phoma rudis 

 and Septoria rudis, belong to Ophiobolus rudis, and other observa- 

 tions (Tul. Carp. II '^^} might also imply this.

Its perithecia are common in autumn on the lower part of leaves 

 of grass and on stubble of the cereals. It attacks the gramineae in 

 summer causing the straws to break at the base (see R 00 a). Especi- 

 ally in the year 1909 this fungus caused great damage; on later in- 

 vestigations it has, however, been proved that this fungus might not 

 be responsible for the whole damage, probably species of Fusarium 

 have been more guilty. The perithecia does not ripen until spring. 

 Mangin supposes Coniosporium rhizophilum (Preuss) Sacc. to be the 

 conidial fructification of this species. 



Very common on Hordeum sativum, Triticum sativum &. repens, rare on 

 Secale cereale.
