On dead leaves of Cunvcdlaria maialis. King's Cliffe, Kortlis. 

 abundantly, Rev. J/. J. Berkeley. — The plant published by Mougeot 

 and Nestler under this name is certainly quite different, and I conceive 

 more properly belongs to tiie genus Dothidea.

 perithecia innate slightly prominent mouthless black seated on 

 a crust-like white spot. Pers. Syn. p. 90. Hooli. Scot. 2. p. 8.

On green \c^\c?. o{ J'lgopodium Podagaria. Common. — The sjiot 

 on which tlie perithecia are seated is not defined, as in the next 

 division. 



Div. 28. Depazea. (As-a^, a cup, from the collapsed or 

 depressed per itheciei.) Perithecia seated on an arid spot, on leaves

On green Ivy-leaves, all tl)e year. Common. — Other similar forms 

 are pointed out b}' Dr. Joiinstou which do not appear to have been 

 noticed by authors. Tiiat on leaves of the Ash dillcrs in having brown- 

 ish spots with a narrower border and the j^crithecia more scattcreil. 

 There is one on Ejnlohiiun ai)giistifolium, with angular spots and the 

 pcrithrrid becoming visible from beneath in conseqncnce of the .sheHing 

 off' of the epidermis on the under-side of the leaf. The .'jpots on iMiiple 

 leaves, to which he alludes, appear only a iliscoloration of the leaf from 

 the agency of insects. Of those on common Docks and on Gciim rivali\ 

 I cannot speak, iiaving no si)ecimens before me. — .V. uucdunicohit 

 Klotzsch, MJSS., which is extremely common on the Strawberry-tree, 

 has small spots w ith a few rather more ()ointed pcritht'cia. An allieii 

 form or species is comnmn on tlic leaves of the Red Cmrant. One on 

 elm leaves is preserved in Dr. Hooker's Herbarimn, marked l)y Klotzs. li 

 Depnzca Ulnii. I do not think it advisable to multiply species in this 

 and sinjilar obscure departments of fimgi, without more correct nt)tiors 

 of their individual structure and more careful nucrosco|)ical investiga- 

 tion than icems at [>resent to have been bestowed upon thcai.
