Lepiota fuscosquamea (Pk.) Sacc. — In Agaricaceae of 

 Michigan, p. 633., I reported a plant collected in northern Michi- 

 gan, as L. felina Fr. This I now consider to be L. fuscosquamea 

 Pk. I have since collected the latter species in the Adirondack 

 Mountains, and am convinced that the spore size given by Peck 

 is misleading, and should be 6-8.5 x 3.5-4 jj.. In the North 

 American Flora, Murrill assigns spores to it, smaller even than 

 the size given by Peck. Lange (9) tried to unite this species 

 with one he collected in Europe and which he considered to be 

 L. hispida Lasch. The spore size of Lange's plant is given as 

 5-6 X 2.75-3 fjL, and the shape oval, hence the two species can- 

 not be combined. Although it may be thought a fine distinction, 

 it may be worth while to point out that the spores of L. acutae- 

 squamosa and L. Friesii in this country, are constantly at least 

 one micron less in width than in L. fuscosquamea. Its gills are 

 simple. The floccose covering on the stem is dense and breaks 

 up into erect, conical, blackish scales. This blackish color is 

 distinguishing. 



Lepiota gracilis Pk. and "Lepiota gracilis" Quel.- — 

 Peck's name apparently antedates the use of the name by Quelet 

 for his variety of L. chjpeolaria. Both Lange (9) and Rea (13) 

 seem to have missed this use as a varietal name, since they have 

 raised Quelet's variety to the rank of a species, crediting Quelet 

 with it. (See Fkwe Monographique des Amanites et des Lepiotes, 

 p. 66.) Peck's species is remarkable for the small size of the 

 plant which is said to have a conspicuous, persistent, membra- 

 nous annulus. Lange (9, p. 24) has described a plant which he 

 calls L. gracilis Quel. var. laevigata. As indicated in the synopsis 

 earlier in this paper, this deserves specific rank and is therefore 

 renamed L. laevigata Lange, comb. nov. 



Lepiota mastoidea Fr. — This is another Fresien species 

 not very well understood in Europe. Since Rea gives the spore 

 characters of the plant which he places here, we can look for it 

 more confidently. The plant described by Morgan (Jour. Myc, 

 13: 2, 1907) is at least not that of Rea, and probably is a dis- 

 tinct American species. Bresadola {Ann. Myc, 18: 65. 1920) 

 considers L. porrigens Viv. a synonym of it. Ricken (14) in-
