XXIV.—Synopsis of the Fructification of Jf Simple Sphæriæ of iia Hookerian 
‘ Herbarium. By FREDERICK Currey, Esq., M.A., F.R.S., F.L.S. 
&. ; 
Read May 5th, 1859. 
Ina paper published in the last Part of the‘ Transactions’ of this Society, I have figured 
and described the fructification of all the species of compound Sphæriæ contained in the 
Hookerian herbarium, that is to say, of all those species whose fruit was sufficiently 
perfect. Sir William and Dr. Hooker having kindly afforded me the same facilities for 
the examination of the other great division of the genus, that is the simple Sphæriæ, I 
am now enabled to lay before the Society the result of my examination of the remaining 
species contained in their herbarium. I adopt the course pursued in the former paper, 
of prefixing a short account of the characters på f the sections and divisions, as given in the 
‘Systema Mycologicum.’ ^ 
Most of the plants described in the ox: paper kake to thé genus Sphæria as 
limited in Fries’ ‘Summa Vegetabilium Scandinaviz,’ but a few are referrible to some of 
the new genera proposed in that work, and I have noted such of the species as belong to 
the new genera, and have given the characters of such genera in the notes, as they occur. 
The simple Sphæriæ commence with the 5th Section, * SUPERFICIALES.” 
SECTION V. SUPERFICIALES.—Perithecia free, bicorticate, seated on an effused villous subiculum, 
or altogether superficial. - a " 
Div. 17. Byssisepx —Perithecia free, glabrous, with a short subpapillæform ostiolum, seated on 
a tomentose subiculum, formed of densely interwoven threads. 
Div. 18. ViLLosæ — Perithecia. ovate or globose, clothed with simple persistent down; en 
even, subpapillæform, rarely elongated or obsolete. | 
Div. 19. Denupatæ.—Perithecia naked, ovate or globose, glabrous, without kg Fr
