DOTHIDEALES 



The system of Theissen and Sydow (39) will be followed here 

 in its entirety. 



DOTHIDEACEAE 



Dothidina peribebuyensis (Speg.) comb, no v. 



Phyllachora peribebuyensis Speg., Fung. Guar. 1 : 274. 1883. 

 Auerszvaldia Miconiae P. Henn., Hedwigia 43 : 253. 1904. 

 Bagnisiopsis peribebuyensis (Speg.) Th. & Syd., Ann. Mycol. 

 13:292. 1915. 



Dothidina Miconiae (P. Henn.) Th. & Syd., Ann. Mycol. 13: 

 298. 1915. 



A comparison of the type material of Phyllachora peribebuy- 

 ensis Speg. (Balansa — Plantes du Paraguay No. 3854) and that of 

 Auerswaldia Miconiae P. Henn. (Ule — Appendix Mycotheca Bra- 

 siliensis No. 27) has shown them to be the same fungus. Theissen 

 and Sydow seem to have overlooked this fact and have proposed 

 new combinations for each, placing them under different genera. 



The fungus is by no means a Phyllachora. Garman (16) identi- 

 fied the specimens collected by Stevens as P. peribebuyensis, but 

 admitted that the species might possibly fall under Bagnisiopsis. 

 Working with material from Colombia, H. and P. Sydow (41) 

 also made the mistake of referring the fungus to P. peribebuyen-
