In 1914 I received fine specimens of the plant from Thore C. E. 

 Fries, collected in Lapland, where it is said to be very common in 

 the mountains. Mr. Fries sent it under the name "Calvatia bore- 

 alis, n. s.," which I advised him was correct (cfr. Letter No. 49), as 

 I had overlooked the specimen at Kew. I do not know that he ever 

 published it. The several specimens from Mr. Fries showed marked 

 difference in the cortex, the warts of some specimens of same collec- 

 tion being much smaller. Also the sterile base though scanty, is 

 evident in some and absent in others. In 1910 there was published 

 and figured in the Fungi of Denmark Expedition to Greenland, under 

 the name Calvatia arctica, a plant that, from the description, is 

 doubtless the same species. I have never seen the figure. It was 

 collected in East Greenland, Lat. 77 degrees. The main description 

 accords, though there are a few discrepancies from the plant as I 

 know it, viz., "Spores yellowish. Capillitium rarely 7j^ mic. in 

 diameter." We believe it will prove to be the same plant, described 

 from not fully matured specimens. 



The specimens from Prof. Dearness were collected at Kay Point 

 in the Arctics, August, 1914. It is the fourth collection known.
