244 FOLIICOLOUS SPHJERLE. 
The limits of the present paper forbid me now to include either the 
rostrate species of leaf Spheria, or those included in the genera Isothea, 
Hypospila, and Stigmatea, but I hope at some future period to revert 
the genera of Foliicolous Sphæriæ now omitted. 
Venturia, De Not. 
Perithecia fragile, hispid or setulose at the apex. Ostiolum large. 
Paraphyses none. Sporidia 2-celled, slightly coloured.—De Notaris 
in Att. vi. riun. scienz. p. 485; Fries, Summ. Veg. Scan. p. 408 ; 
Cooke, Brit. Fungi, 2nd edit., pp. 159. 
1. VENTURIA Dicxrer. Forming orbicular sori beneath the true 
cuticle about a line broad.  Perithecia at length exposed, subglobose, 
with an obtuse papilleform ostiolum beset with stiff dark bristles, as 
long or longer than themselves, springing from a radiating, more or less 
interwoven stratum, of very obscurely septate brownish threads, amongst 
which are a few darker and closely articulate. Asci short, subcylin- 
drieal, obtuse. Sporidia oblong, short, containing about four nuclei or 
four regular endochromes, or more properly uniseptate, with two endo- 
chromes in each division.—Spheria Dickiei, B. and Br. Ann. Nat. Hist. 
n. 617, pl. x. f. 8; Berk. Outl. p. 395 ; Cooke, Index, n. 2179. La- 
siobotrys Linnea, Dickie, mss.; Berk. Outl. p. 404; Cooke, Index, 
n. 3011. Venturia xat De Not. Schema, p. 51.—On leaves of 
Linnea borealis. (P1. XLIX. Fig. 1.) 
ENTURIA EREs. Scattered over the leaves and quite superfi- 
cial, attached by a few hyaline creeping threads. Perithecia globose, 
beset with very long radiating, rigid, somewhat pellucid, articula 
bristles, which are black to ii naked eye, but purplish-brown under 
the microscope; when young their apices are often swollen. Asci 
rather short, clavate. Sporidia biseriate, oblong-elliptic, about four 
times as long as broad.—Spheria Eres, B. and Br. Ann. Nat. Hist. 
n. 621 (Pl. IX. Fig. 4) ; Berk. Outl. p. 395 ; Cooke, Index, n. 2195. 
Venturia Eres, De Not. Schema, p. 51.—On dead leaves of Carices. 
(PI. XLIX. Fig. 2.) 
3. VENTURIA CHÆTOMIUM. Hypophyllous, rarely epiphyllous. Pe- 
rithecia very minute, superficial, scattered or gregarious, sabglobose, 
collapsed when dry, black, covered with rigid lrei hairs, ostiolum 
papillate. Asci nearly spindle-shaped. Sporidia oblong, straight or 
slightly curved, containing four sporules or nuclei, *007 mm. (700027 in.)
