long by half as wide, cotaposed of two globose cells united into an 



oblong spore. 



When the epidermis is peeled off, the perithecia generally adhere 



to its inner surface. 



On dead limbs of Ilex opaca. March. 



Valsa CERCOPHORAT^Perithecia few, 4 to 6, rather large, imbed- 

 ded in a subcarbonaceous stroma, which is circumscribed by a black 

 line penetrating the wood ; ostiola stout, obtuse, with a large open- 

 ing, united into a subconical disk, which pierces the epidermis and 

 rises slightly above it ; asci clavate-cylindrical, .oo3'-.oo33'x.ooo4'- 

 .00045'; sporidia biseriate, oblong-elliptical, constricted in the mid^- 

 dle and appendiculate at each end, .0004' — .ooo6'x.oooi5'-,oooi75', 



hyaline, with several small nuclei. 



The appendages, which are finally absorbed, are as long as, or 

 longer than the spore itself, and the upper one is generally recurved 

 at its extremity. The limbs on which this species grows are not so 

 much decayed as those on which the preceding species is found, 

 being still sound and tough. 



On dead limbs of //p: opaca. March. 



Valsa farinosa.— Stroma cortical ; perithecia few (2 to 4,) pale, 

 .013' in diameter, raising the bark into little prominences, which in- 

 dicate their position ; disk tuberculiform, yellowish white, of a loose 

 granular or mealy substance ; ostiola large, pale horn-color, ovate or 

 conic, at length disappearing and leaving a large opening ; asci cla- 

 vate-cylindrical, obtuse ; paraphyses indistinct ; spondia i- or 2-seri- 

 ate, acutely elliptical, subhyaline, with a large central nucleus, about 



.ooo6'x.ooo2 . 



Very variable with regard to the ostiola, which are often entirely 

 wanting. Some of the stromata contain perithecia filled with brown, 

 appendiculate stylospores of about the same size and shape as the 

 ascospores, and which appear referable to Dr. Cooke's genus Hark- 



nessia.

Fern Notes. V. 



By Geo. E. Davenport. 



....,...^.,.^ tenera. Gillies.— This rare fern, which Dr. Parry found 

 so unexpectedly in Utah, in 1S74, has again turned up, but this time 

 in the San Bernardino Mountains of California, where it was dis- 

 covered in May last by the Parish Brothers, who write that it was 

 found "growing very sparingly in two neighboring canons at an 

 altitude of perhaps 5,000 feet. In both places it grew in crevices of 

 precipitous limestone cliffs, which were quite dry at the time of our 

 visit and do not seem to be ever really wet. In one canon there 

 was a single specimen, and in the other some twenty or more,^ but 

 most of them dry, and the others, as you see, in poor condition. _ 



The specimens which I have received are clearly identical with 

 the Utah plant, and differ but little from Parry's or Palmer s speci- 



mens. 



It'has already been recorded (Ferns of North America, Vol. 1., p. 

 .,7) that some doubts exist in regard to the correct identity of the 

 Utah plant, but the figure in Botanical Magazine- (Vol. Iviu., plate
