spores slightly cymbaaform, -0008 inch long, -00016 wide, with 

 from three to four nuclei. 



456. Asteroma atramentarium. B.~ Nigerrimum compactura 

 expansum ; floccis radiantibus reticulatis ; peritheciis minutis ; 

 sporis brevibus subcymbyformibus. On leaves of Amelanchier and 

 Pyrus arbutifolia. Car. Inf., No. 1773. > 



Forming broad black patches, with a reticulated radiating border ; 

 perithecia minute ; spores shortly cyrnbiform, about -0005 long. 



* Asteroma Robergei. Desm.— On the inner side of stems of 

 Arundinaria. Car. Inf., No. 3213. 



Endobotrya. B. § C— Perithecia abdita ; sporse clavatse pedun- 

 culate ; episporium reticulatum ; endosporium e cellulis globosis 

 nucleatis transversim subseriatis. 



457. Endobotrya elegans. B. & C. — On branches of beech. 

 Maine. No. 5703. Perithecia concealed by the bark ; spores "002 inch 

 long, oozing out and forming black orbicular patches, clavate, pe- 

 dunculate ; external coat hyaline at first, continuous, then reticu- 

 lated; endochrome consisting of globose nucleated, at length sepa- 

 rable divisions, which are at first arranged in transverse layers. 

 This is probably a state of some Sphasria, but the structure is so 

 curious that for the present it is left under the name originally 

 proposed. 



458. Cytispora orthospora. B. $ C- — Pustulis parvis, demum 

 erumpentibus planis ; sporis lineari-oblongis. On Robinia. Penns., 

 Mich., No. 5158. New Jersey, No. 4681. 



Pustules at length bursting through the bark, plane above ; peri- 

 thecia with a flat expanded base ; spores *0004 inch long. In the 

 Pennsylvanian plant the pustules are quite concealed by the bark, 

 having probably not arrived at maturity, and the spores are rather 

 longer, -0005 inch. 



459. Cytispora abnormis. B. <& C. — Pustulis minutis apice tantum 

 erumpentibus ; sporis oblongis binucleatis. On twigs of Robinia.

 tion of the apex ; spores oblong, -0003 inch long with two nuclei. 



460. Cytispora parva. B. & C. — Pustulis minutis apice tantum 

 punctiformi erumpentibus ; peritheciis globosis ; sporis oblongis 

 angustis enucleatis. On twigs of Robinia. Car. Inf. No. 3424.

 globosis, sporis oblongis curvulis. On twigs of fig. Pennsylvania,
