6 b. A. muse, forma aureola (Kalkbr.). 



Spores subrotund-ovate, 9 x 7 u. 



Fig. specim. : Gerup Skov, near Holstenshus, under Betula and 

 Sarotbamnus, in grass. Not as distinct variety, only a slender 

 form without warts. — A. Frostiana Peck seems almost identical. 



7. A. pantherina (DC). 



Spores ovate or broadly oval, 8 — 12 X Q 1 / 2 — 1 1 / 2 u. — Edge of 

 gills with cells of various shape, mostly cylindric-vesiculose, 

 about 12 u broad (1914). 



Fig. specim.: Hjallese, wood of Fagus, Oct. 1896 and »Fruens 

 Bøge' Sept. 1905. — Not uncommon, often solitary, chiefly in 

 outskirts of woods of Fagus, occasionally met with in grassy 

 spaces in young plantations of Picea. 



The ring is almost even, not conspicuously radiately striate 

 as in the following species. The warts are pure white, the edge 

 of the gills finely crenulate. The colour of the cap varies from 

 dark fuscous-brown to very pale, almost white. 



[A. velatipes Atk. (from America) appears (judging from the 

 description) to be almost identical]. 



8 a. A. excelsa Fr. 



Spores subrotund-ovate, 8—10 x 5 x / 2 — 7 u-. Edge of gills set with 

 globular large cells (diam. 20 — 35 u). 



Fig. specim.: Gerup Skov near Holstenshus, wood of Picea, 

 July 1900. — Rather rare. Appears rather early in the season. 



Base of stem deeply set in the substrate; most of the mealy- 

 mem branaceous veil is wiped off as the fungus pushes up 

 through the deep layer of dead needles etc , below which it is 

 developed. — It is often paler than shown in my figures; an 

 extreme form is: 



8 b. A. excelsa Fr. forma pallida. 



Spores subglobular-ovate, 9 x Q x / 2 u; basidia about 9u broad with 

 4 sterigms. 



Fig. specim.: Same locality as no. 8a, July 1914. 



The surface of the cap is somewhat moist or sub-viscid. 



[A. cariosa Fr. seems to me only a slender form of A. excelsa. 

 The fungi, which I have called A. excelsa, are almost exactly 

 intermediate between the descriptions of the two species, the 

 larger specimens approaching the excelsa-type, the smaller ones 

 A. cariosa. The larger ones have the innate fibrils of excelsa, 

 and their stem is squamulose, but the base of the stem is only 

 sub-bulbous and the cap rarely reaches the dimensions attributed 

 to A. excelsa. 



A. excelsa seems for the rest to be rather differently conceived 

 by the mycological authors. Cooke figures it with a greenish-
