1632. Sp/ueria hevigata, Scliw. — Form? a continuous, smooth, 

 black crust widely effused (6 inches), determinate, surrounding the 

 limb. Perithecia scattered, large, globose-depj-essed, deeph' immersed, 

 their ostiola appearing as mere points on the surface of the crust. 



On soft, rotten wood, Bethlehem, Pa. (Sclnv.). 



1633. Sphceria inundatorum, Schw. — Gregarious, covered by 

 a widely effused, rimose crust, so that the wood appears charred. 

 Perithecia scattered, buried in the wood lieneath the crust, globose- 

 depressed, without any distinct neck, but with flattened-globose ostiola 

 erumpent through a crustaceous tubercle, and finally pezizoid-umbili- 

 cate.

1684. Sphceria excussa, Schw. — Perithecia large, thickly scat- 

 tered under the partially loosened epidermis, immersed in the inner 

 bark. Ostiolum punctiform, barely piercing the epidermis, but finally 

 elongated into a distinct beak perforated at the apex. The large, 

 flask-shaped rugose perithecia surrounded with a distinct furrow, also 

 emerge, and when mature, easily fall out, leaving pits in the bark two 

 lines across. 



Frequent on young bi-anches of Pyrus Malus, Bethlehem, Pa.

1625. Sphceria denudans, Schw. — Scattered and aggregated, 

 oblong-globose, depressed. Perithecia immersed, at length subpromi- 

 nent, inner cavity elliptical, enclosed in a kind of cinerascent mem- 

 brane finally black. Ostiola very small, papilliform, situated in a 

 slight depression in the top of the perithecium, sometimes hysteriiform. 



On limbs, Bethlehem, Pa. (Schw.). 



1636. Sphceria Rosce, Schw. — Scattered on a dark brown crust 

 widely effused under the epidermis, finally denuded. Perithecia sub- 

 immersed in the crust, hemispheric-prominent, oblong-globose, rugose, 

 black. Ostiola at first scarcely piercing the epidermis, at length 

 short-conical. 



On tender branches of rose bushes. New Jersey (Schw.). 



1637. Sphceria aynpelos, Schw. — Minute, distantly seriately
