FURTHER NOTES ON ANTHURUS BOREALIS. 
W. W. Stockberger. 
In a recent note on Anthurus borealis Burt, (Ohio N.aturalist 
6:474, 1906) D. R. Sumstine states that he has not seen it re- 
ported from any other places than those localiites in New York 
and Massachusetts recorded by Burt when he described the 
species in 1894. 
Lloyd {Mycological Notes, No. 17, p. 183, 1894) acknowledges 
the receipt of some specimens collected by Beardslee near Cleve- 
land. Ohio. Later a short account of the occurrence of Anthurus 
borealis in northern Ohio, by Beardslee, was published by the 
Ohio State Academy of Science (9th Ann. Kept. p. 19, 1901). 
The occurrence of this fungus at Granville, Ohio, was reported 
before the Ohio Academy at its annual meeting in 1901 (10th 
Ann. Kept. p. 20, 1902), and this station is further recorded in 
Lloyd’s Mycological Notes (No. 19, p. 219, 1905) along with some 
previously unrecorded New England stations, one at East Hart- 
ford, Conn., one at Storrs, Conn., and several in Massachusetts. 
Its further occurrence as noted by Sumstine would seem to 
indicate that this species of Anthurus does not occur so rarely as 
has been supposed, and that its occasional occurrence through- 
out Ohio may be safely predicted.
