FURTHER NOTES ON ANTHURUS BOREALIS. 



W. W. Stockberger. 



In a recent note on Anthurus borealis Burt, (Ohio Naturalist 

 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. Rept. 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. Rept. 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.
