' Sph^ma (Seriate) Matdis: maculis parvis, subellipticis, elevatis; pe- 

 ritheciis paucis, ostiolo uriico, conico ; sporidiis oblongiis, curvulis, uniseptatis. 



.Habit that of Spharia arundinacea. Spots minute, often purple-brown, 



punctiform or subelliptic, rarely linear, containing very few perithecia, with a 

 single broad conical ostiolum ; sporidia oblong, slightly curved, uniseptate. — 

 Very different from Spharia Zea, Schumin., as appears from an authentic speci- 

 men in Sir W. J. Hookefs Herbarium. 



2 Sphhsbia (Btssisdje) HHODOMFHAI.A : peritlieciis demum confertis, minu- 

 tis, globosis umbilicatis, atris, plus minus, prassertim circa ostiolum obsoletuni) 

 miniato-pruihatis, sub lente scabriusculis subiculo fusco insidentibus. Berk, in 



Hook. Lond. Journ.,Mo\. iv. p. 313. Scattered, at length much crowded, 



either free or seated on a matted brown subiculum : perithecia globose, at first 

 powdered with vermilion which is more or less persistent in the centre; 

 ostiolum simple, umbilicate ; asci somewhat lanceolate, pedicellate ; sporidia 

 lanceolate, constricted in the centre with a single septum, and containing one 



or sometimes two nuclei. A pretty species, but rather difhcult to place, as 



the subiculum is sometimes entirely wanting and the perithecia are rather 

 pulverulent than villous. It has almost equal claims to take its place amongst 

 DenudatcB VilloscB and Byssisede. 



3 Sph^bia (Subtect^) abgxbostigma : epiphylla ethypophylla late dis. 

 persa ; peritheciis minoribus depresso-globosis, epidermis tectis astomio j ma- 

 culis epidermalibus, punctiformibus, nigris centro candidis sporidiis cymbifor- 

 mibus, pellidis. Appearing like scattered Phoma, but it has distinct asci.
