1408. Glseosporiuxn concentricuxn. B.^'Br. "Concentric 



Glffiosporium." 



Minute, white, disposed concentrically; spores numerous, 

 cylindrical, truncate, pellucid, oozing out and forming little 

 heaps. — B. ^ Br. Ann. N.H. no. 441. Cylindrosporium concentri- 

 cum, Grev.t. 27. Uredo cylindrospora. Eng.Fl.Y.p.SS4:. 



On living cabbage leaves. 



Spores produced beneatli the cuticle, and forming little heaps by oozing 

 out, as in other species. 



1409. Glseosporium labes. B. S; Br. " Poplar-leaf GI^os- 



porium." 



Spots indefinite, brown ; spores sub-pyriform, obsoletely uni- 

 septate, sub-cirrhose. — B. ^ Br. Ann. N.H. no. 440. Asteroma 

 lubes. Berk. exs. no. 346. Ann. N.H. no. 203, t. 11,/. 6. 



On Hving poplar leaves. Jul. 



Forming irregular brown patches, scattered or occupying almost the whole 

 of the upper surface of the leaf, the stroma when held up to the light is 

 found to be disposed in a fibrillose form ; spores forming short tendrils, sub- 

 pjriform, with an obscure septum (not always visible) at the contracted part 

 of the spore. The spores in the fresh plant show little granules, generally 

 disposed in two patches. — M. J. B. 



1410. Glaeosporium. leeticolor. " Salmon-coloured Glffios- 



porium." 



Spots depressed, centre white, with a black ring, pustules cir- 

 cinating, tendrils pale red, spores oblong, the endochrome re- 

 tracted at either end. — Berh. Gard. Chron. ISbd.j^P- 604. 



On peaches and nectarines. 



At first appearing as dark specks with a bleached centre , at length the 

 white spot and dark ring become more clearly defined, seated in the centre of 

 a regular circular depression, the borders of which are pale. The whole sur- 

 face of the depression studded with little salmon-coloured warts, disposed 

 more or less in circles, from which issue little curled tendrils of salmon- 

 coloured spores ; spores oblong jgL in. long, with their contents retracted 

 to either end. 



1411. Glaeosporium fiuctigenum. *' Fruit Glfeosporiura." 



Pustules concentric, of two forms, one opening in a stellate 

 manner, with apical spores, the other opening by a pore, with 

 the spores forming a gelatinous tendril. — Berk. Gard. Chron. 

 lSb6,pp.2AbJg. 



On apples. 



Studding the fruit with pearl-like specks, bursting through the cuticle, 

 and swelling above it in the form of little fiat cushions. Sometimes single, 

 more frequently surrounded by a more or less perfect ring. Each plant
