panicle, occasionally bearing one or two branchlets ; radical leaves 

 lanceolate, sparingly villose, 3-6 lines long, cauline leaves narrowly 

 lanceolate or linear, acuminate, 6-12 lines long, 1-1.25 lines broad, 

 minntely pubescent beneath, glabrous above, or one or two lower 

 ones sometimes with a few long scattered hairs, the sheaths mostly 

 shorter than the internodes and minutely pubescent, stipules a tuft 

 of slender bristlelike hairs .5-1 line long; panicles ovate in outline, 

 6-12 lines long, the branches and pedicels glabrous, spikelets sub- 

 globose or oval, less than .5 of a line long, the first scale minute, 

 glabrous or nearly so, second and third scales nearly equal in length, 

 minutely pubescent, the second commonly purplish. 



Moist or w^et muddy soil. Shore of Little pond about 2.5 miles 

 south of Wading River, Suffolk co. August. 



This diminutive panic grass has smaller spikelets than any 

 species I find described. In most of its characters it approaches 

 closely to P a n i c u m p s a m m o p h i 1 u m Nash from which 

 I have separated it because of the smaller size of all its parts, its 

 different mode of growth and different habitat. This is wet humus 

 or decomposed vegetable matter which is apparently submerged in 

 times of high water. The mode of growth is scattered, not cespitose, 

 and the pubescence except at the base of the stem is so minute that 

 it is scarcely visible to the naked eye. Unless carefully examined 

 with a magnifying glass the plants would be considered glabrous. 



Peckiella hymenii n. sp. 



Subiculum white, overrunning the hymenium of the host plant 

 and obliterating the lamellae, sometimes interrupted ; perithecia 

 minute, globose, semiimmersed in the subiculum, numerous, pale 

 honey color becoming darker with age; asci linear, .009-.013 of an 

 inch long, .0003-.0004 broad ; spores monostichous, fusiform, acute 

 at each end, hyaline, .0016-.0018 of an inch long, .00025-.0003 

 broad, oozing from the perithecia and forming irregular whitish 

 masses upon them. 



On the hymenutm of Lactarius vellereus Fr. Wad- 

 ing River, Suffolk co. August. 



The parasite in all the specimens seen, is limited to the hymenium 

 of the host plant, the upper surface of the pileus and the stem 

 remaining unchanged. The host plant also retains its acrid taste. 

 The perithecia are so numerous that they give a general pallid hue 

 to the parasite, though the subiculum itself is white. The emitted 

 spores, adhering in minute masses, do not cover the surface with
