HDutypella scoparia (Schw.) BE. & BH. On bark of Ulmus fulva, Hamilton 
County, December 31, 1915. G. B. Ramsey. 3678. 
Gyromitra esculenta (Pers) Fr. Campus, May 8, 1910. Owens. 2783. 
Hypoxylon perforatum (Schw.) Fr. On decorticated elm, Mason’s Woods, 
November 1, 1920. 3797. The perithecia were just arriving at maturity, 
and had not yet become perforate to any extent. This specimen resembles 
certain forms of H. rubiginosum and H. fuscopurpureum very closely. The 
stroma is % to 1 mm thick, effused in oval or elongated areas 1 to 4 em long. 
Color, ferruginous to chestnut-brown. Perithecia slightly elongated (1% 
mm long). Asci long tapering, 150 to 190 by 6 to 9; p. sp. 75 to 85 by 6 
to 9. Spores mostly 13 by 6%. 
Hypoxylon serpens (Pers.) Fr. On dead wood of red-oak, Boone County, 
December 20, 1915. Ramsey. 3566.

Nectria episphaeria (Tode) Fr. Parasitic on Valsa on beech bark, May 
5, 1916. W. P. James. 38679. Makes the bark a beautiful red over large 
areas. 
Nectria Ipomoeae Hals. On young sweet-potato plant, spring of 1916 
(Sphaeronema fimbriatum on this same plant). 3706.

County, January 17, 1914. Ramsey. 3675. 
Teichospora vialis (Fr.) Berl. & Vogl. On decorticated Juglans cinerea, 
November 20, 1913. Ramsey. 3674. 
Valsa Linderae Pk. On Lindera benzoin, April 21, 1917. Hanger. 3736.

cades, April 18, 1920. Mills. 3768.

Sphaeropsidales. 
Actinonema Tiliae Allesch. On leaves of Tilia americana. Both on and 
under tree late in autumn. 3691. 
Dothiopsis eunomia Karst. May 19, 1917. 38740. This species was first 
described by Karsten in Hedwigia 1884 under the name of Dothiora eunomia. 
Phylosticta Liriodendri Thuem. On living leaves of Liriodendron tulip- 
ifera, Campus, July 24, 1916. Hemmer. 3696. 
Phyllosticta Smilacis E. & E. On leaves of Smilax rotundifolia, Brown 
County, October 10, 1914. Weatherwax. 3687. Spores vary slightly from 
the description as follows: 15 to 25 by 5 to 8 microns. One of the most 
striking things about this fungus is that one rarely finds spores in the 
pyenidia. We had systematically collected it for years but found the 
pyneidia empty. In Torr. Bull., 1900, p. 572, Ellis and Everhart say: “This 
has been observed on various smooth-leaved species of ee for twenty 
years or more, but it does not appear to have been described.” The probable 
reason for this is its habit of ridding itself of spores so quickly. 
Septoria albaniensis Thuem. On leaves of Salix nigra, autumn. 8692, 
Our measurements of spores are: 25 to 42 by 2% to 3 microns.
