HYPHOLOMA AGGREGATUM AND H. 

 DELINEATUM 



Edward T. Harper 

 (With Plate 12) 



Since I published the notes on the Hypoloma lacrimabundum 

 group of Agarics in Trans. Wis. Acad. Sci. Arts and Letters, Vol. 

 XVIII, p. 412, Prof. Beardslee of Asheville, N. C, has sent me 

 specimens and photographs of two of Peck's species, Hypholoma 

 aggregatum and Hypholoma delineatum, with the suggestion that 

 the former is the same as Hypholoma Storea var. caespitosum, 

 Cke. As this species is what Maire and others consider the true 

 Hypholoma lacrimabundum of Fries and is at least a fine addi- 

 tion to my Hypholoma lacrimabundum group and as these speci- 

 mens of Hypholoma delineatum clear up a doubtful point in my 

 article I will publish a few notes on the species and also the 

 photographs with the kind consent of Prof. Beardslee. 



1. The identity of Hypholoma aggregatum Pk. and Hypholoma 

 Storea var. caespitosum Cke. 



I have never collected Hypholoma aggregatum but a com- 

 parison of Beardslee's specimens with Hypholoma aggregatum in 

 Shear's N. Y. Fun. No. 13 and with Hypholoma Storea var. 

 caespitosum in Jaap's exsicatti No. 143 shows that there is at 

 least a very close relationship between the two forms. Beardslee's 

 photograph accompanying this article is also very similar to W. 

 G. Smith's illustration of Hypholoma Storea in the Jour. Bot., 

 Vol 14, tab. 176. The latter represents the plant since de- 

 termined as Hypholoma Storea var. caespitosum. 



The species belongs to what I have called the Hypholoma lacri-
