and prominent light-colored veins, ovate or ovate-lanceolate,two inches 

 long, entire or with a pair of coarse teeth, or hastate lobes at base, 

 abruptly tapering into a short, winged petiole ; flowering branchlets 

 leafy below, naked above and terminating in a loose corymb ; invo- 

 lucre shorter than the disk; rays conspicuous; akenes sparingly vil- 

 lous and bearing a pair of stout, persistent awns of more than their 

 own length. 



The specimens lie in the herbarium of the California Academy, 

 marked *'Cedros Islands," and were probably brought thence, many 

 years ago, by Dn Veatch. 



MiCRosERis (EuCALAis) ATTENUATA. — Leaves inciscly and "^ 

 deeply pinnatifid, the divisions linear; scapes about a foot high ; in- 

 volucre ^ inch long, and narrow; akenes fusiform, 4-4!- lines long, 

 very slender, especially from midway upwards ; pappus 4^-5 lines 

 long, the elliptic-lanceolate scale more or less villous, and about 

 one-third the length of the slender, strongly barbellate awn. 



Collected by the writer on the 25th of April, 1882, on the grounds 

 of the University of California, at Berkeley, where it grows in great 

 abundance, as also on the hills adjacent. The akenes and pappus 

 are extremely long and slender for the group into which it falls, but 

 it is only as to length that they resemble those of the Calocalais 

 section. The plant is a genuine Eucalais^ a section whose best tech- 

 nical character is one which does not appear to have been recognized 

 by any author, namely, the peculiar convolute aestivation of the pap- 

 pus-scales. But the adoption of this character would exclude from 

 the group M, Bigelovii^ which has the imbricated aestivation, though 

 not the habit of Calocalais.

Valsa LUTESCENS, — Stroma cortical; perithecia subglobose, 10 to 

 15, subcircinating, disk at length erumpent, brown, convex, with the 

 short, cylindrical, stout, obtuse,svibstelIate-cIeft ostiola ranged round 

 its circumference; asci lanceolate, spore-bearing part .001 3'x.ooo25'; 

 sporidia cylindrical, hyaline, curved, .ooo25'-.ooo3'x,oooi'. 



On dead limbs of Quercus coccinea, January, The wood beneath 

 the bark occupied by the fungus is generally stained light yellow. 



(N. A. F., No. 876.) 



Valsa binoculata. — Perithecia 3 to 6, rather large, closely im- 

 bedded in a stroma formed of the substance of the inner- bark, and 

 circumscribed by a black line which doe^ not, however, penetrate 

 to the wood ; ascigerous nucleus white, soft and pasty when fresh ; 

 ostiola erumpent through cracks in the epidermis, subglobose, with a 

 large irregular opening; asci clavate-cylindrical, .005' — .co6'x.oo6'- 

 ^ .0007'; paraphyses stout and granular ; sporidia uniseriate, broadly 

 elliptical, nearly hyaline, uniseptate and constricted, with a large 

 nucleus in each cell, .0008' — .ooo9'x.ooo5' — .00055'. 



The ostiola are often entirely concealed so that outwardly there is 



no trace of the fungus. 



On dead trunks of Magnolia glauca.
