460. Phoma Eucalypti, Cooke § Harkn. 



Certainly not a Phoma \ a vague mycelial growth, in which 

 few and uncertain spores and absolutely no pycnidium could be 



detected. 



461. Phoma Eucalyptica, Sacc. 



Coniothyrium Eucalypti, Thiim. 1879, Moller, no. 401 ! 



Specimens very imperfect, with few pycnidia or spores. But, 

 on the other hand, there were a large number of perithecia of 

 Didymella recedens, Sacc, with asci and biseriate spores, 16 x 

 3 //., bearing at each end appendages 1 or 2 /x long. (Fig. 22 . 



D. recedens, from Moller, no. 401. 



465. Phoma longispora, Cooke. Leptothyrium longisporum, 



Thiim. 



Macrophoma longispora, Berl. & Vogl. in Sacc. Svll- Addit. 



p. 312. 



There are, under this name, a number of specimens (Ravenel, 

 no. 2605 I), as issued by Cooke, on branches of Vitis aestivalis, 

 from Aiken, South Carolina. On these no spores like those 

 described by Thumen could be detected. But there was a con- 

 siderable quantity (mostly immature) of Guignardia Bidwellii 

 (Ellis) V. & R. = Physalospora Bidwellii, Sacc, Syll. i. 441. 

 Not a few asci and spores were found quite mature, and agreeing 

 exactly with the descriptions and figures. As these specimens 

 were issued in 1879, while Dr. Bidwell found the perithecia for 

 the first time in 1880, it is evident that Ravenel really collected 

 them first. His specimens are on the stems, which are sur- 

 rounded and covered by vast numbers of perithecia. 



469. Phoma coniluens, Berk. 8f Curl. 



The specimens in Herb. Berk. (no. 5616!) are very imperfect; 

 this species should be deleted. 



478, Phoma fraxinea, Sacc. 



So far as the specimens, Koumeguere, no. 4350!, are con- 

 cerned, this does not differ from Cytospora ambiens, Sacc. on 

 the same host. 



484. Phoma Syringae, Berk, fy Curl, (see Sacc, Syll. iii. 82, 



sub Phoma syringica).
