5274, on branches of Berber is, is Phomopsis berberina, Grove 

 (see below); and (3) no. 5185, on petioles of Aralia spinosa, is 



the one for which Berkeley's specific name melaleuca should 

 be retained, as this species appears not to have been met with 

 elsewhere. 



Phomopsis berberina, Grove. 



Phoma berberina, Sacc. & Roum. in Rev. Mycol. 1880, p. 191. P 



Sacc. SylJ. iii. 72. 



Pycnidia scattered or loosely gregarious, without any stroma, 

 subepidermal, globose-depressed, brownish-black, about 300 /x 

 diain. Snores fusoid, acute at both ends, biguttulate, 7-8 x 2 fi', 

 sporophores at first ampullifoim, tapering sharply upwards (i.e., 

 strongly obclavate), 9-12 x 3 fi wide at the tiase, afterwards 

 more elongate, subulate, 12-14 x 1*5-2 /x, rising from a thick 

 olivaceous stratum. (Fig. !)• - *

On branches of Berberis, Tarbes, France (Rouin. no. 1015 !) ; 

 New England, Sprague (Herb. Berk. no. 5274!). 



Certainly different from Phomopsis detrusa, Trav. Pycnidia 

 very imperfect. All the English specimens which I have seen 

 under the name Phoma berberina were not fully developed, but 

 did not in any case belong to Phoviopsis. 



Phomopsis Melaleuca, Grove. 



Phoma melaleuca, Berk. & Curt, in Grevill. 1873, ii. 82. 

 Sacc, Syll. iii. 73, p.p. 



Pycnidia scattered, oblong-depressed, 300-400 /x long, im- 

 perfect, black, covered by the epidermis and each surrounded 

 by a deep brown stain, piercing the epidermis by the short ostiole. 

 Spores broadly fusoid, acute at both ends, biguttulate, 7-9 x 

 2 5-3 /x; sporophores subulate, 12-15 x 2 fx. (Fig. 2).

P. melaleuca from Berk. no. 5185 



On petioles (not branches) of Aralia spinosa, Alabama, Peters 

 (Herb. Berk. no. 5185 !). This is not likely to belong to Diaporthe 

 Araliae, E. & E., since that is a Chorostate ( = C. Araliae, Trav.).
