269. Phomopsis sitbordinarta Trav. 



A large quantity of this was gathered on Plantago lanceolata at 

 Earlswood Lakes station, in October last year. In these specimens 

 the B-spores far outnumbered the A-spores which occurred in the 

 same pycnidia ; they were of the usual character, straight, curved, 

 flexuous, bent, or hooked, about 20-23 x |-1 ^. This makes another 

 species in which both kinds of spores have been found ; the list of 

 such, given in the Keio Bulletin, 1917, p. 50, must now be increased 

 by the following : — 



Pliomojjsis corticis. 

 „ Eres. 



,, pustulata. 



„ querceUa. 



,, siihordinaria. 



Moreover in that article, p. 60, it was stated that the phenomena 

 described by Diedicke, dvie to the parasitic habit of this species, had 

 not been observed in Britain. Hardly were these words in print when 

 they became untrue : the exact course of events described by him was 

 seen for the first time in two places near Birmingham. The curved 

 peduncle with its drooping spike was very noticeable, and has since 

 been met with as early as June ; the pycnidia are to be seen on the 

 curved part while the spike and the lower part of the peduncle are 

 still fresh and vigorous. Evidently one of tliose things to be found 

 easily when one knows what to look for. The following species of 

 Phomopsis may noAV be regarded as parasitic : — 



P. ahietina, on Pinus, etc. (see no. 271). 



P. aucuhicola, on Aucuha. 



P. corticis, on Rnhus. 



P. Stewaftii, on Cosmos. 



P. subordinaria, on Plantago. 



270. Phomopsis vepris v. Hohn. Fragm. Mykol. no. 87, p. 33. 



Plioma vepris Sacc. Syll. iii. 76. 



Pycnidia gregarious, small, round, immersed, globose-depressed, 

 blackish, about 200 \x diam., at length just piercing the epidermis. 

 Spores fusoid, 5-7 x 1-1^ [x ; sporophores crowded, linear, erect, hardly 

 longer than the spore, rising from a yellowish fertile stratum. 



On dead stems of Pubus, Eastham Kake, Cheshire (Ellis). The 

 pycnidial stage of Piaporthe vepris Fckl. et Nits. The pycnidia 

 here also are incomplete, but do not i-esemble those of P. corticis, so 

 that it seems possible that the two species are different in spite of 

 their similarity ; the sporophores especially are different. The British 

 specimens in Herb. Kew under this name do not belong to Phomojysis 

 (see Kew Bulletin, 1917, p. 71), but Dr. Ellis's certainly are correct. 



SCLEROPHOMA Died. 



A genus resembling Phoma in most respects, but it is without 

 an ostiole and the lower part of the pycnidium is filled with a well- 

 developed stroma, consisting of cells similar to those which form the 

 mass of a sclerotium. There are no sporophores, the spores are seated
