CRYPTOGAMIA FUNGI. 129 



48. S. JEgopodii, black, minute, somewhat prominent and round- 

 ish, scattered or clustered, placed in pale coloured irregular spots. 

 PERS. Syn. 89. HOOK. Scot. ii. 8. MOUG. and NEST. No. 281. 

 Cryptosphceria JEgopodii, GREV. Fl. Edin. 362. 



Hab. On the green leaves of the gout-weed, in summer 

 and autumn, scattered over pale spots which map the 

 whole leaf, and seem determined in their outline by its 

 reticulation. 



49. S. Angelica, scattered but very numerous, minute, black, 

 prominent, roughish, the apex obtuse or depressed. S. punctifor- 

 misy var. Angelicaria, DEC AND. Fl. Franc, vi. 145. 



Hab. On the inferior side of the leaves of the wild ange- 

 lica in autumn, common. 



Nearly allied to the preceding. The portions of the leaf in- 

 fested with it assume a pale-yellow colour, but sometimes 

 the whole leaf is covered, and ^without visible discoloration. 

 It is only found on the inferior surface. 



50. S. maculiformis, minute, point-like, roundish, black, cluster- 

 ed on small squarish and blackish spots. PERS. Syn. 90. MOUG. 

 and NEST., No. 661. 



Hab. On oak, chestnut, and also on birch leaves, common, 

 opening on the inferior surface. 



On comparing my specimens with those in MOUGEOT and 

 NESTLER'S collection, I find them precisely similar, a 

 circumstance I mention because the species, notwithstand- 

 ing its commonness, has not previously been introduced 

 into any British Flora. It infests decaying oak, chestnut, 

 and birch leaves in autumn and winter. The capsules have 

 their origin beneath the epidermis, and several are collect- 

 ed together into small squares, or irregular spots of a black- 

 ish colour, each spot dotted with the scarcely prominent 

 points of the cells. 



51. S. sentina, cells minute, gregarious but distinct, immersed, 

 globular, black, white internally; orifice exserted, subglobose. 

 SPRENG. Syst. Veg. iv. 403. S. grossularia? Sot. Gall. ii. 709. 



Hab. On the dead leaves of the blackberry and hawthorn, 

 previous to their fall from the bushes, scattered over the 

 whole inferior surface.
