Ceratostomella. 



The species of Ceratostomella often corresponds to conidial fructi- 

 fications of the formgenus Sphaeronema, viz: 



Ceratostomella subpilosa corresp. Sphaeronema subpilosum (Fuckel). 



— procumbens — — procumbens (Fuckel). 



— pilifera — — piliferum (Saccardo). 



— multirostrata — — Fuckehi (Saccardo).

Cucurbitaceae. 



The species of Cucurbitaceae often produce more different forms 

 of conidial fructification belonging to the dark-spored Sphaerioideae. 

 Otthia, Gibberidia and Cucurbitaria quite regularly produce Diplodia 

 and Camarosporium besides the ascigerous stage. The life-cycle of 

 Nitschkia and of Gibbera is, however, quite different, viz: 



Nitschkia cupularis corresp. to Phoma Fuckehi (see Saccardo). 



Gibbera vaccinii — Helminthosporium vaccinii (see 



Wt. II ^'^). 

 Otthia populina Diplodia populina.
