G—8 micr. long. Differs from the preceding species as noted in the 
description. Distance between the extreme septa 12—15 micr. 
Polyscytalum CYLiNDROiDES, Sacc. & Ell. — Hyphis e basi 
paullo incrassata subcylindricis, brevibus, subfuligineis subsim- 
plicibus; catenulis passim ramosis; conidiis cylindricis, utrinquo 
obtuse-rotundatis, spurie 1-septatis, 15—20 x 2J—3. On fallen 
leaves of Quercus virens and Q. aquatica , Pointe a la Haclie, 
La., Feb. ’87. Rev. A. B. Langlois, 1073. Hyphae short, cylin¬ 
drical, thickened below, brownish 25—35 x 2J—3, subnodulose, 
subsimple. Chains of conidia occasionally branched. Conidia 
cylindrical, rounded at the ends, spuriously, 1-septate, 15—20 
x 2J —3. Differs from Cylindrium in its brownish hyphae — and 
from Polyscytalum fecundissimum, Riess. in its nearly simple 
hyphae—from P. sericeum it differs in its conidia not swollen at 
the ends and its less effused habit, forming small subpulvinate 
tufts mostly less than 1 mm. diam. 
Verticillium dichotomum E. & E.—On dead clover stems 
(Trifolium pratense) Newfield, N. J. Aug. ’88. Snow white, 
fertile hyphae erect, 70—80 x 3—4, snbverticillately or oftener 
dichotomously branched above, the branches straight septate, 
pointed and about 20 x 3 micr., bearing at their tips the oblong- 
clavate, continuous, hyaline 6—12 x 2—3, solitary conidia. The 
hyphae form minute, scattered tufts scattered evenly over the 
matrix and not confluent. 
Botrytis rhinotrichoides, Sacc. & Ell.—Parasitic on old 
Stemonites, on Sphagnum , Newfield, N. J. Hyphis subsimpli- 
cibus, eximie verticillato-spiculoso-sporigeris; candidis subglobosis, 
4 x 3 J—4. Ad genus Rhinotrichum valde accedit, Hyphae 
subsimple bearing the subglose conidia on short spicules verti- 
cillately arranged. 
Botrytis tephroidea, Sacc. & Ell.—Cinerea. Hyphis parce 
erecto-ramosis, rarius asperulis; conidiis apiculaMs, oblongo- 
cllipticis, 8—9 x 4—5. Ad B. geniculatam accedit, sed distincta. 
On decaying stems of Ambrosia trifida , Pointe a la Hache, 
La. Rev. A, B. Langlois, No. 1048, on rotten wood, No. 1226. 
Cinereous whit6. Hyphae with a few erect 'branches, slightly 
roughened. Conidia oblong-elliptical, apiculate. Forms thin, 
continuous patches on the matrix. 
Botrytis fasciculata, E. & E.—On decaying logs in damp 
places. Louisiana. Rev. A. B. Langlois, 1231. Hyphae fascic¬ 
ulate, di-trichotomously branched, the branches cylindrical, straight, 
erect, subhyaline and occasionally slightly denticulate at the tip. 
The lower part of the fasciculate hyphae coalesce so as to form
