Hone: two r.ASiniOMvcETEs new to Minnesota. 63 



The Minnesota specimens dififer from those described by Burt : 

 (I.) in the much larger convoluted masses, some being four inches 

 in diameter, (2.) in the nearly spherical and much smaller basidio- 

 spores, 2-3 niic. in diameter. 



Cantharellus retirugus (Bull.) Fries. 



This fungus was first classified by Gmelin in Linnaeus' "Sys- 

 tema Naturale" 2: 1401 (1735), as Meruliiis reticxdatus. Since then 

 it has been described by BuUiard in his "Champignons" p. 289 

 (1791), as HclvcUa rctiruga and by Persoon in his "Synopsis" p. 

 494 (1801) as Mendius retirugus. Fries in 1821, in the "Sys- 

 tema mycologicum," 2 : 324, was the first to place it under Cantha- 

 rellus^ where it seems to belong. Hennings in Engler and Prantl 

 (1897), has followed Karsten in breaking up the old genus Can- 

 tharellus, as described by Adanson in Juss. Gen. p. 6 (1789) and 

 places this genus under Leptotus. 



The fungus has been found several times in Europe and espe- 

 cially in England, as Cooke and Sowerby both record it. The Min- 

 nesota collection is the first recorded from America the writer be- 

 lieves. The fungus was found in the early spring, April 1903, by 

 -\Ir. N. P. B. Nelson. It was growing abundantly upon the coarser 

 mosses, especially species of Hypnum in a swamp near the Fish 

 Hatchery, St. Paul. 



Cantharellus retirugus is closely related to C. muscigenus (Bull.) 

 Fries and C. lobatus (Pers.) Fries. It differs from the former in 

 not being truly stipitate, although some specimens show a short 

 pseudostipe. It also is not villose and the veins are strongly anas- 

 tomosing or reticulate. It differs from C. lobatus in being laterally, 

 that is, never centrally attached, and the gills are more truly retic- 

 ulate than in C. lobatus. Again the spores are not spherical or oval 

 but are broadly elliptical. 



Cantharellus retirugus (Bull.) Fries. 



Pileus to .75 inch in diameter, membranaceous expanded, re- 

 pand, fan-shaped, margin wavy and lobed darker at edge, near 

 point of attachment, cinereous white to tan or brown at margin; 

 darker beneath, subsessile or expanded into a short flattened stipe- 

 like base at one side, fixed by Httle fibrils ; upper surface minutely 

 scabrous ; beneath gills radiating from point of attachment, thin, 

 reticulate and anastomosing; basidia short, simple, two to four
