stems of Heracleum Sphondylium, 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 scar cely presenting a definite perithecium. Spores 
narrow oblong, subelliptic, but by no means filiform. 
This species has somewhat the appearance of Sph. amberbis, 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 Phoma according to Fries’ notion of the genus, but has not 
a sufficiently definite ‘perithecium to justify its being placed in 
Spheropsis, which it seems is to receive such fungi as have uni- 
locular spores seated on sporophores and a definite perithecium. 
Tt will however probably be found necessary to place certain 
species with extremely minute spores in Spheronema, or if the 
hyaline elongated species alone are to remain in that genus, in 
Zythia, Fr. M. Desmaziéres 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. Desmaziéres’ 
definition. 
395. P. nothum, nu. s. Tectum ; peritheciis spuriis subtus hic 
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 Spheropsis 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.

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
