subocbraceous, about as thick as the stem and often a little widened 

 at the top. Being hollow it causes the unruptured sporangium to ap- 

 pear deeply umbilicate or pervious. The filaments of the capillitium 

 often adhere for a time to the base of the columella as a pale-yellowish 

 flocculent mass. The exterior surface of the sporangium is scaly, but 

 the number and size of the scales vary considerably in different speci- 

 mens. This singular species may hereafter be deemed worthy of ge- 

 neric distinction, but for the present it is thought best to refer it to the 

 genus Physarum.

Phoma herbarum. Went. Dead stems of white daisy, Leuca?ithe-

Phoma Phytolacca^ B. & C. Dead sterns of poke weed, Phytolacca 

 decandra. Verona. Aug. The perithecia are sometimes covered by 

 the whitened epidermis, sometimes exposed. They occur on both the 

 exterior and the interior surface of the hollow stems. They are de- 

 pressed, orbicular, elliptical or oblong, and are furnished with an osti- 

 olum which pierces the covering epidermis. Sometimes two or more 

 are confluent in a linear manner. The spores are about .0005 in. long 

 and contain from four to six nuclei.

Phoma hysteriellum, P. & C, n. sp. Perithecia immersed, slightly 

 prominent, mostly hysteriiform, covered by the epidermis, black, with 

 a minute papilliform ostiolum ; spores elliptical or subfusiform, color- 

 less, binucleate. .0003 in. long. Dead stems of herbs. Buffalo. Nov.

Leptothyrium punctiforme, B. & O. Perithecia minute, .0025 in. 

 to .0042 in. broad, subhemispherical, black, shining, openin'g by a sub- 

 circular or irregular aperture, pale within ; spores subfusiform, curved, 

 colorless, .0005 in. to .0008 in. long. 



Living leaves of daisy fleabane Erigeron ammum. Quaker Street. 

 June. The perithecia are so minute that they are but just visible to 

 the naked eye. The fungus attacks the lower or basal leaves, which 

 soon become yellowish in color and wither.

Hendersonia abnormalis, n. sp. Perithecia numerous, small, sub- 

 conical, surrounding the stem on all sides, seated on smoky-brown spots, 

 raising small pustules in the bark, at length rupturing the epidermis 

 and opening by a small round aperture; spores elliptical or oblong, 

 colored, .0006 in. to .0011 in. long, about .0004 in. broad, three to six- 

 septate, the cells divided by longitudinal lepta. 



Dead stems of bitter-sweet, Cclastrns scandens. Charlton. July. 

 This fungus occurred in company with Sphxeropsis Celastri, from which 

 it is easily distinguished by the brown discolored spots it occupies. 

 Colored filaments sometimes surround the perithecia. The ostiola are 

 usually whitened. 



Hendersonia Coluteae, P. & C.,n. sp. Perithecia prominent, erump- 

 ent, hemispherical or subconical, firm, cellular, ostiola black, papilli-
