MR. F. CURREY ON THE FRUCTIFICATION OF SIMPLE SPHJERLE. 327 
brown, triseptate, ör with the endochrome 4-partite, surrounded by å narrow gela- 
tinous border. Perithecia small, conical or somewhat flattened, sometimes only just 
piercing the bark, sometimes protruding considerably. Sporidia ejected in vast 
numbers, forming wide black stains round the ostiola, 0-0026 inch long. On dead 
branches of (I think) maple, Blackheath Park, 1855 and 1856. This plant is the 
type of the genus Saccotheciwm of Fries, the characters of which seem to me most 
unsatisfactory, and to have been founded upon imperfect microscopical observations.

Sporidia dark brown, with a granular and nucleated endochrome, very variable in 
size, sometimes reaching 0:0080 inch in length.

rich brown, eventually becoming very dark brown, oblong, constricted in the middle, 
surrounded by a broad gelatinous envelope, 0:0008 to 0-0011 inch long. Not un- 
common on dead branches of oak. One of the finest Spherie in point of fructifica- 
tion. The figure in the ‘ Annals’ conveys no idea of the beauty of the sporidia, being 
hardly more than an outline.

0:0007 inch long ; endochrome 4-partite, giving a triseptate appearance. a

not quite certain whether this plant is the true S. Tilia of Persoon. It is Dot un- 
common, and cannot be mistaken for any other if attention be paid to its fruit, and 
to its growing upon lime. In fig: 105 and fig. 106 I have represented asci with T 
sporidia and free sporidia of a Sphæria on lime, communicated to à by n 
Berkeley as S. Tiliæ of Mougeot and Nestler. The sporidia of this gna ex "d
