124 CRYPTOGAMI AFUNGI- 



. 27. S. millepunctata, capsules numerous, distinct, globose, black, 

 small, immersed beneath the epidermis ; the orifice very short, 

 obtuse, scarcely exserted GREV. Syn. 24. Cryptosphceria mille- 

 pumtata, GREV. Fl Edin. 360. Crypt. FL t. 201. 



Hob. On decaying small branches of the ash, which, when 

 infested with it, seem to the naked eye covered with in- 

 numerable minute black dots. 



28. S. Tilia, scattered, immersed and covered by the epidermis, 

 dull black, circular, depressed, the margin raised and thickened ; 

 orifice central, short, and thickish PERS. Syn. 84. MOUG. and 

 NEST., No. 660. 



Hal. On small decayed branches of Sycamore. 



This fungus, about y^th of an inch in diameter, sits im- 

 mersed in the meshes of the old and fibrous bark, concealed 

 by the epidermis, which forms a discoloured and rather 

 depressed spot immediately above it. In the centre of 

 this spot the apex of the capsule is visible, but it scarcely 

 protrudes. On removing the epidermis, the sphceriais ex- 

 posed, remarkable from its situation between the meshes 

 of the netted bark. A closely allied species grows on the 

 old stalks of Epilobium angustifolium. 



j- -f Seated upon the bark or wood. 



29. S. aquila, capsules seated in a byssoid cinereous base, globu- 

 lar, clustered, large, black, smooth, with a very minute papillary 

 orifice __ Bot. Gall. ii. 697. S. byssiseda, GREV. FL Edin. 363.

Hob. On decayed branches, rare. Winter. 



The capsules of this fine species are fully as large as the 

 seeds of the Swedish turnip, and are placed either in close 

 apposition, or a little remote, covering in this manner the 

 branch for several inches in extent. Our specimens are 

 on hawthorn, and were gathered in the immediate vicinity 

 of Berwick by my nephew and pupil Mr R. DUNLOP. 

 The form of the capsules is mammillary, and it is as regular 

 as if it had been fashioned in the lathe of the turner. The 

 summit is rounded and encircled with a line, forming an 

 areola around the minute orifice. The byssoid or floccu- 

 lent base is of a dirty ash colour ; the filaments short, ri- 

 gid, irregularly branched and opake. Its presence is pro-
