aceous, plurilocular, the loculi opening into a common out- 

 let; sporidia subcylindrical, usually nearly straight, hyaline, 

 escaping in a tendril. Very near Cytiapora, differing in 

 little save more regular loculi and. straighter sporidia. 

 *55- 0. phacidioides, Grev., i6i8 3 C. 360, S.M., 3070 (D. and 

 R. Trail, 1886). 

 On dead leaves of Ilex Aquifolium, along with Phacidium 

 Bids Fr., to which it has been assigned as a stage.

 56. 0. Lauri, Grev., 1628, C. 36, M. 11 75 (D. and R. Greville).

 (Sphaeropsis differs from this genus only in the larger 

 arid firmer pycnidia and the longer basidia, bearing larger 

 sporidia usually.)
