Siome change!^ in Nomenclature of South African 

 Ascomycetes. 



By Ethel M. Doidge. 



A I'umber of publications inaccessible during the war 

 have recently been received in the Agricultural Department 

 Library ; amongst these are the Annales Mycologici from 

 T 913-1919, our numbers being previously complete only to 

 the end of 1912. A number of valuable papers <m the 

 Ascomycetes have been published during this period by 

 Theissen and Sydow, and these necessitate some changes 

 in nomenclature in certain fungi described from South 

 Africa. 



The genus Meliola Fr. comprised a large number of 

 species, some with and some without mycelial and 

 perithecial setae. (S.A. Jour, of Nat. Hist. 2.) The genus 

 Meliola is now restricted to species with a hyphopodiate 

 mycelium and with mycelial or perithecial setae; a new 

 genus Trene, Theiss & Syd. Has been established for 

 species without setae, (Ann. Myc. 15. (1917.) 194.) the 

 type being Irene inrrmis (K. & Cke. sub. Meliola) Th. & 

 Syd. 



The following South African species are affected by this 

 change of nomenclature: —
