Kectrta (('alonectria) fulvida, E. & E.-On bark of decaying 

 oak limb lying on the ground, Xewfield, N. J., Oct. 7, 1885. Perithecia 

 superficial, gregarious, subglobose, small (1-6 mm.), tubercuiose-squamu- 

 lose, light yellow, collapsing above when dry. Ostiolum large but not 

 prominent. Asci oblong-cylindrical, nearly sessile, obtuse, about 75 x 10 

 —12 !J-, surrounded by indistinct paraphyses. Sporidia8 in an ascus, fusi- 

 form, hyaline or nearly so, slightly curved, 38—50 x 3—31 /-'-, tapering 

 from ihe middle to each end, nucleate, becoming about 8-septate. The 

 specimens were growing on the bark of an old swelling caused by JDidi- 

 (p.na strumoso., Fr. 



jSTectria atrofusca (Schw.), Syn. N^. Am. No. 1429.— On dead 

 limbs of Stapliylea trifolia, West Chester, Ta., Oct., 1885 (Everhart.) 

 Densely crowded on a tuberculiform stroma 1— li mm. broad, and easily 

 separable^from the bark into which its base is sunk. Perithecia (20—40) 

 minute (1-6 mm ), depressed, conic, black, rough except the subconic, 

 somewhat polished ostiolum which is at length radiate-sulcate cleft. 

 A"sci about 75 x 16 /^-, oblong-cylindi ical ; sporidia hyaline or nearly so, 

 oblong-elliptical, or sometimes a little narrower at one end, 1-septate, 

 very slightly constricted, 10—72 x 41—5;^-, ends obtuse. In some cases 

 the perithecia were found growing around the margin or on the bare 

 wood in the bottom of the little pits from which the stroma had fallen. 

 The mature sporidia have a smoky yellow tint. This appears not to have 

 been met with before since Schweinitz's time. 



Hypoorea coRTici ^fpE^, E. & E.— On bark of dead limbs of Mag- 

 nolia glauca, Newfield, N. J., Aug. 1885. Stroma thin, milk white with 

 the margin slightly cottony, forming a continuous layer extending along 

 the limb for six inches or rQ ore, finally becoming dirty white and crack- 

 into small areas as in Corticium polygonium, Pers. Perithecia globose, 

 pale, 75 in diameter, bedded in the stroma and visible under the lens as 

 horn-colored specks. Asci clavate-cylindrical, 20—22 x 3i /^-, sessile. 

 Sporidia partly biseriate, 8 in an ascus, each consisting of two globose, 

 hyaline cells about 1 p- in diameter and easily separating. The stroma (?) 

 appears to be a true Corticium with clavate-cylindrical basidia bearing 

 subglobose, 3 /j- spores. If we adopt this view the ascigerous perithecia 

 are parisitic on the Corticium and might be referred to Hypoiiiyces but 

 for the sporidia which are those of Hypocrea. It is certainly a very 

 peculiar fungus.
