DECADES OF BRITISH FUNGI. 
By M. C. Cooxg, Eso. 
(Pirate XLV.) 
Dec. I.-VII. 
The fungi described in the following pages have been chiefly col- 
lected during the past twelve months. For several of these I am in- 
debted to the assiduity of Dr. Edward Capron, of Shere, w hose devotion 
to the study of microscopie fungi will, I trust, in the future, contribute 
materially to the number of species that I may have to include in the 
* Decades." The species enumerated by Messrs. Berkeley and Broome, 
in the ‘Annals of Natural History’ (vol. xv. April, May, June, 1865), 
will not be included, and, therefore, to those communications by my 
excellent friends the following may be regarded as supplemental :— 
ERYSIPHEI. 
I have to record several interestiug additions to this group, two of 
which belong to a genus not before determined as British. 
Popospuzra, Kunze. Mycelium effuse, web-like, evanescent. 
Conceptacles spherical, containing one, subglobose, 8-spored sporan- 
gium. Spores ovate. Appendages few, dichotomous, thickened at 
their extremities, hyaline —Léveillé in ‘ Annales des Sciences Na- 
elles.’ 
1. PoposPH RA KUNZEI, Lév. Amphigenous. Conceptacles mi- 
nute, scattered, globose. Appendages three times the length of the 
diameter of the conceptacles.—Lév. Ann. Sc. Nat. 1851, xv. p. 135. 
Alphilomorpha tridactyla, Wallr. Fl. Crypt. ii. p. 738. Erysibe tri- 
dactyla, Rabh. D. Krypt. Fl. p. 237; Desmz. Ann. Se. Nat. ser. 3. 
t. iii. p. 361. Erysibe Brayana, Weigt. Reg. Bot. Zeit. 1838, p. 473 ; 
Rabh. D. Krypt. Fl p. 237.—On the leaves of Prunus domestica. 
Shere, near Guildford, September, 1865 (Dr. E. Capron). (PL XLV.

9. PODOSPHÆRA CLANDESTINA, Lév. Amphigenous. Conceptacles 
minute, globose, scattered. Appendages (8-10) equal in length to the 
diameter of the conceptacles. Branches short and rounded at their ex- 
tremities.—Lév. Ann. des Sc. Nat. 1851, xv. p. 138. Exysiphe Ozy- — 
acanthe, De Cand. Fl. Fr. vi. p. 106 ; Duby, Bot. Gall. 868; Cast. -
