 stems of Heracleum Sp ho nd>/ Hum, Guernsey, Nov., Rev.T. Salwey. 



Unilocular, forming little pitch-brown rather convex dots with 

 a paler cloudy narrow border. Mass of spores surrounded by a 

 dark cellular stratum, consisting of hexagonal cells confused with 

 the matrix, but scarcely presenting a definite perithecium. Spores 

 narrow oblong, subelliptic, but by no means filiform. 



This species has somewhat the appearance of Sph. imberbis, Fr. 

 We have not yet seen the text of the ' Flora Algerensis/ and can- 

 not therefore avail ourselves of the characters of Phoma and its 

 allied genera as worked out by Dr. Montagne. Our plant is a 

 good PJwma according to Fries' notion of the genus, but has not 

 a sufficiently definite perithecium to justify its being placed in 

 Sphceropsis, which it seems is to receive such fungi as have uni- 

 locular spores seated on sporophores and a definite perithecium. 

 Jt will however probably be found necessary to place certain 

 species with extremely minute spores in Sphceronema, or if the 

 hyaline elongated species alone are to remain in that genus, in 

 Zythia, Fr. M. Desmazieres has lately proposed as the distin- 

 guishing character of Phoma, spores with a sporidiolum at either 

 extremity. If this view is rigorously followed, our species must 

 find another habitation. In point of fact the names assigned to 

 these obscure fungi must, till the genera are settled, be consi- 

 dered provisional. We add one or two species, which, with the 

 exception of the first, accord exactly with M. Desmazieres' 

 definition. 



395. P. not hum, n. s. Tectum ; peritheciis spuriis subtus hie 

 illic elevatis ; sporis obovatis. On dead plane twigs, Batheaston, 

 February, C. E. Broome. 



Pustules slightly raised. Perithecia spurious, orbicular, the 

 base protruding here and there into their cavity. Spores obovate, 

 rather pointed at the narrow extremity. 



This cannot be placed in Spharopsis on account of its spurious 

 perithecium, which has a tendency to become multilocular, and 

 the spores do not accord with those of Cytispora ; for the present 

 therefore we are compelled to place it with the last in Phoma.

396. P. radula, n. s. Tectum, peritheciis teneris lato-conicis ; 

 sporis oblon go-ell ipticis. On dead twigs of plane, Batheaston, 

 C. E. Broome, Feb. 1850. 



Sprinkled over the twigs, which it renders rough like a little 

 rasp or grater. Epidermis split on each perithecium. Perithecia 

 delicate, composed of subhexagonal cells; spores minute, oblong- 

 elliptic, with a sporidiolum at either extremity. Very rarely we
