(Chondrioderma spumarioides ), Adirondack Mts., X. Y., August, 1882. Dr. 
Geo. A. Ilex. 
Peritkecia minute, less than one fourth millim. in diam., flesh-color, 
becoming darker, slightly compressed laterally, enveloped in white down, 
which forms little tufts, appearing under the lens like some minute, 
tufted, mucedinous growth ; asci linear, 35—40 /■>■ long, evanescent; 
sporidia uniseriate, oblong, hyaline, 1—2-nucleate (becoming uniseptateV).

or violet. 
148. Gibberella pulicaris (Fr.) S: M. II, p. 417. 
Csespitose, stroma cortical; perithecia crowded, superficial, purplish, 
at length collapsing or laterally compressed; asci oblong, sessile, 
8-spored, GO —75 x 12—16 ! J -; sporidia biseriate, ovate, elliptical or subpy- 
riform, subobtuse, somewhat curved, 3-septate, pale yellowish, 18—20 x 
6—8 l J -. The conidial stage is considered to be Fusarium sambucinum , 
Fckl., or F. roseum , Lk. This is quite a common species and is found on 
bark of dead limbs of various deciduous trees and on dead herbaceous 
stems—especially on dead stalks of Zea Maps and also on the grain. 
149. Gibberella Saubinetii, Mont. Sacc. Syll. II, p. 554. 
Perithecia gregarious, confiuent-csespitose and concrescent, coriaceo- 
membranaceous, verrucose, at length flaccid, plicate, ovoid, subcon¬ 
tracted at the base, bluish, 200—300 x 170—220 papillate ; asci oblong- 
lanceolate, acuminate above, contracted at the base into a short, thick 
stipe, 8-spored, 60—76 x 10—12 :>■; sporidia uniseriate or subbiseriate, 
fusiform, curved or straight, subacute, 3-septate, but scarcely constricted, 
nearly hyaline, 18—24 x 4—5 ! l ; conidial stage, Fusarium roseum , Lk. 
The characters of this species, as here given, are taken from Sacc. Sylloge. 
From the specimens at our command, we have always found it difficult 
to separate this from the preceding species.

150. IIyponectria Gossy t pii (Schw.) Syn. Car., No. 207. On dead 
capsules of cotton plant, Carolina (Schweinitz). 
Scattered, rather soft, immersed, perithecia globose, purplish flesh- 
color ; ostiolum elongated to the surface and discharging gelatinous 
matter. The minute perithecia are deeply sunk in the substance of the 
immature capsules so as not to be seen unless the capsule is cut open, 
but, through the elongated ostiola, a gelatinous substance is discharged, 
which hardens on the surface of the capsule and gives it a purplish color. 
In the mature specimens the surface of the capsules is granulose or 
papillose from the subjacent perithecia. We have seen no specimens of 
this species, but we have received from Prof. F. L. Scribner a Fusarium 
on capsules of cotton from South Carolina, which may be the conidial 
stage.
