FUNGI : CONIOMYCETES. 283 



(1.) = the Stilbospora microsperma of the Berw. Fl. ii. p. 192. 

 See Berkeley in Ann. and Mag. N. Hist. Ser. 2. v. p. 377. — The 

 Stilbospora biloculataof Berw. Fl. ii. p. 192, is a species of Diplodia. 

 Ann. Nat. Hist. vi. p. 365. 



(2.) "Dr. Johnston finds a beautiful variety on Asperula odo- 

 rata." Berkeley in Ann. Nat. Hist. vi. p. 439. — This variety was 

 found in the dean at Twizell-house. 



(3.) My specimens are on the leaves of Sanicula europeea. 



(4.) This is the ^mut or ^SlacfesbaH of our cereals. Our farmers 

 know very well the difference between it and Uredo segetum, but 

 they do not distinguish them by name, — that of Smut being com- 

 mon to both species. Black-ball is, however, limited to U. caries. 



(5.) This is the Bust of corn, familiar to every one engaged in 

 agriculture. 



(6.) Ann. and Mag. N. Hist. Ser. 2. v. 463. — I have observed 

 this to infest, for many years in succession, the leaves of a few plants 

 of the Valerian where it grows at the side of the footpath a little 

 beyond the Old Castle ; but I have never seen it anywhere else in 

 our district. Difference of season makes no difference in the appear- 

 ance or abundance of the parasite. I have observed the same fact 

 in regard to the production of some Erysiphes, as has been also 

 noted by Link. Willd. Sp. Plant, vi. p. 101. 



(7.) In 1831 I first discovered this species on Spittal Links, where 

 it had attacked the culms of the grasses (Festucse and Pea;) ex- 

 tending over a considerable space ; and handfuls of specimens might 

 have been easily gathered. Mr. Berkeley has favoured me with the 

 figure of it engraved on Plate X. fig. 2 ; and he has recorded its 

 habitat in Ann. and Mag. Nat. Hist. vi. p. 439. — From the date of 

 my first finding it imtil July 1851, the plant did not once occur to 

 me ; and the original habitat was frequently searched*. At the latter 

 date I found it infesting the Rye-grass on the road-side near Belford 

 Station ; where I also saw it in 1852. 



Spurious Fungi. 



Rhizomorpha subcorticalis. Erineum betulinum. 



divergens. populinum. 



setiformis. alneum. 



Erineum pyrinum. Byssus floccosa. 



acerinum. Himantia Candida. 



fagineum. 



* June 27. — To-day I found the parasite again on the grasses of Spittal 

 Links, in profusion.
