Forty- second Annual Report on the 



Lactarius quietus, Fr. 



Low woods. North Elba. Sept. 



Russula purpurina, Q. & S. 



Mossy ground in woods of balsam. North Elba, near Lake Placid. 

 This is a beautiful and very distinct species, easily known by its red 

 stem, mild taste and white spores. 



Cantharellus rosellus, n. sp. 



[Plate 1. Figs. 6-8.] 



Pileus thin, infundibuliform, regular, glabrous, pale pinkish-red, 

 flesh white; lamellae narrow, close, dichotomous, deeply decurrent, 

 whitish, tinged with pink; stem equal, slender, solid, subglabrous, 

 often flexuous, colored like the pileus; spores minute, broadly ellip- 

 tical, .00014 in. long, .0001 broad. 



Pileus 4 to S lines broad; stem about 1 in. long, scarcely 1 

 line thick. Mossy ground in groves of balsam. North Elba. Sept. 

 This small species belongs to the section Agaricoides, and is appa- 

 rently closely allied to C. albidus, from which its smaller size and dif- 

 ferent color distinguish it. The pileus is sometimes deeply umbilicate 



Marasmius peronatus. Fr. 



Thin woods. North Elba. Sept. 



Lenzites heteromorpha, Fr. 



Stumps of spruce. North Elba. Sept. 



In the Thirtieth Report I expressed the opinion that Lenzites CooJcei, 

 Doedalea confragosa, Trametes rubescens, etc., were all forms of one 

 species. In Icones Selectee Hymenomycetum Professor Fries says 

 that L. heteromorpha exhibits three forms, one of which belongs to 

 Lenzites, another to Dsedalea and another to Trametes, thus showing 

 too great an affinity between these genera. The form here noted 

 belongs to Dredalea. The lenzitoid form, which is taken as the- type 

 of the species, was not detected by me. 



Boletus floccopus, Vahl 

 Woods. Selkirk, Albany county. Aug. 



The forms which I have referred to this species scarcely differ from 

 B. strobilaceus, except in having the tubes depressed around the stem. 



Boletus hirtellus, Pk. ms. 



Sandy soil under pine trees. Rensselaer lake, Albany county. Oct.
