XX. Camarosporium Schulz. 



Pycnidia subcutaneous, at last erumpent, separate from one 

 another, spherical, often papillate, membranaceous, or 

 subcoriaceous, dark, sporidia as above. Several of the 

 " species " are spermogonia of Cucurbitaria. 

 *99- 0. Laburni Sacc. and Roum., 2496 (D. & R. Trail, Sc, 

 Nat., 1886, p. 266), S.M. 307.3. 

 On dead branches of Cytisus Laburnum, common. 

 Dee. 

 This is the spermogonium of Cucurbitaria Laburni, which it 

 very closely resembles, save in not possessing asci. 

 *ioo. A similar but unnamed stage of Cucurbitaria Spartii is 

 plentiful on twigs of Cytisus scoparius (Broom) around 

 Aberdeen, and may be called in like manner, Cama- 

 rosporium Spartii. It differs from the Cucurbi- 

 taria only in the absence of asci. 

 *ioi. 0. Oreades (Dur. and Mont.) Sacc. 2526, C.309 {Hender~ 

 sonia Oreades Dur. and Mont, M. n 14). (D. Fergusson).

8. SCOLECOSPORiE. 



Pycnidia as in Hyalosporae ; sporidid slender, filiform, or elongate 

 fusiform, undivided, or septate, hyaline or yellowish. 

 Note. This section grades into Hyalosporce, through 

 certain species of the latter that have slender spores (in 

 Pkoma chiefly), and into Hyalophragmice it passes 

 through certain species of Stagonospora. 



Analytical hey to genera. 



A, Pycnidia separate, not immersed in a stroma. 



Pycnidia complete, small, lenticular, ostiolate, not papillate, 

 very often in discoloured spots on leaves; sporidia usually 

 very slender. Septoria. 



Pycnidia globose-lenticular, but incomplete, on the leaves, but 

 scarcely causing spots ; sporidia stouter. Phleospord.
