456 SHEAR: Mycorocicat NOTES AND NEW SPECIES 
the length of the sporules ; paraphyses abundant in mature plants, 
very variable in length but much exceeding the spore, 2-2.5 # in 
diameter. 
Type on dead, exposed roots of U/mus sp., Lincoln, Neb., no. 
981. C. L. Shear, March 30, 1895. Type material deposited in 
the Myc. Herb. U. S. Dept. of Agriculture. 
In a poorly developed condition the stroma is very small and 
almost simple, suggesting Sphacropsis but examination shows that 
this is an abnormal, aborted state. The cells of the stroma do 
not all appear to be entirely distinct but some seem to connect with 
each other. The spores of this are almost identical with those of 
Sphaeropsis ulmea Ell. & Barth. with type material of which I 
have been able to compare it through the kindness of Mr. Bar- 
tholomew. There is no resemblance between the two plants in 
other respects however. 
PESTALOZZIA GUEPINI vaccinii subsp. nov. 
Sporules elliptic to oblong-elliptic, somewhat inequilateral. 
usually 4-septate, 21-24 x 8-gy. the three central cells dark 
colored, usually guttulate with the septum below the upper 
one darker colored than the others; apical setae 3-4, 22-357 
long; basal seta 6-12. The fungus forms no spots on the 
leaves but develops evenly over the surface of the yellow fallen 
leaves, apparently preferring the lower surface. 
Type no. 1146, on dead leaves of Vaccinium macrocarfon kept 
in a moist chamber in the laboratory for about a week. Plants 
from which the leaves were taken were collected at Parkdale, N. 
J., by the writer. a 
This plant has apparently been referred heretofore to P. guepim, 
Desm. Ann. Sci. Nat. Bot. 2d Ser. 3: 182. 4 4.f. 1-3. 1848. It 
agrees fairly well in many respects with the description and figures 
of that species but differs decidedly from the specimens issued 10 
the exsiccatae at hand. Hosts are given by Desmazierés (/. ¢.) 
as follows: ‘Habitat in foliis siccis Camelliae et Magnoliae”’ and 
his Pl. Crypt. fasc. XXII. is cited as containing a specimen. 
Specimens on Camellia Japonica from three different collections 
(no. 150 Briosi & Cavara, Fun. Par. Pia. Col. no. 974; Saccardo 
Myc. Ven. and an unnumbered specimen from G. W. cunter 
Buffalo, N. Y.) agree well with each other and are well repre” 
sented by the figure accompanying Briosi & Cavara’s specimen> —
