very long filiform stipe, surrounded by numerous filiform paraphyses, 

 125-150 X 5-6 [X : sporidia uniseriate, uniseptate, the septum being 

 very broad and dark brown, elliptical, ends obtusely rounded, not 

 constricted at the septum, with a single large nucleus in each 

 cell (which is very plainly seen in the young smoky-hyaline 

 sporidia, but also observable in older specimens, by close inspection 

 of the cell contents, which are lighter than the very dark brown septa 

 and external cell walls), brown or olivaceous, 10-12 x 3-4 /x In moist 

 cavities on the end of a rotten log, in the woods, Lyndonville, N. Y., 

 Oct., 1905. Etym. bertiana from the resemblance of its perithecia to 

 the rough tuberculate ones of Bertia vwriformis Tode (DeNot). I 

 have re-examined the specimens of AmphisphcBria graiiiihsa E. & E. , 

 in the original collection, and find that Amphispk(V)ia bertiana, while 

 having sporidia about the same size, differs in larger, more closely 

 gregarious perithecia, larger, shining ostiola, in long stipitate asci, 

 and in sporidia not narrowed toward the ends, in equal cells, not con- 

 stricted, and having, also, nuclei. It differs from A. bispherica (C. & 

 E.), in larger, blacker perithecia, and prominent ostiola, and in long 

 stipitate asci, and sporidia not constricted. It was associated with 

 Helotium citrinum (Hedw.), and a Nectria with scattered perithecia 

 having uniseriate, oblong-elliptical, uniseptate sporidia, 13 x 5-6 jJ.. 

 On the blackened surface of the wood on which the fungus grew there 

 were found many of the dark, evidently discharged sporidia of the 

 AmphisphcEria, and a hyphomycetous fungus with septate, branching, 

 hyaline hyphae, 6 fi wide, bearing at the tips, hyaline to smoky- 

 hyaline conidia, which are oblong elliptical, 2-septate, 20 x 6-7 /i, 

 which may be provisionally designated Dendryphium (/) intermixbim.

Perithecia scattered or gregarious, small, clothed with bristle^ 

 which are light brown when young, becoming darker, and which 

 are straight, not denticulate, acute tipped, with a light streak through 

 the center of the hairs, (due, probably, to a parting or cleft in the hair, 

 or formation of a channel, thereby giving the appearance of a stinging 

 hair of a plant, or the sting of a bee {Bonibiis) and its poison channel), 

 150-250 x 7-13 fi. (measurements of the hairs) ; asci broad fusoid- 

 oblong, 8-spored, short stipitate, 80-90 x 10-13 /i ; paraphyses indis- 

 tinct in the crushed cell contents, which are white ; sporidia irregularly
