olive cap, and Schroeter (1. cit.) describes the cap as »glänzend 



gelb«©]. 



9. A. spissa Fr. 



Spores ovate, S x l 2 — 10x6— 7 |u. Basidia 9u broad with 4 sterigms. 

 Globular cells on edge of gills 18 — 30 ja diam. 



Fig. specim.: »Fjellebro« near Kværndrup, in wood of Fagus, 

 July 1914. — Rare. The stem is solid, shorter and stouter 

 than in no. 8, not deeply seated in the ground. The warts on 

 the cap are small, in the center somewhat mucronate, pale 

 grayish and rather persistent. It has the habit of A. rubescens, 

 but no trace of reddish. 



[A. valida Fr. — To judge from the descriptions A. valida and 

 A. spissa show but very little difference. The former is said to 

 turn fuscous when bruised, what my spissa occasionally does; 

 but for the rest the descriptions of A. spissa fit my plants very 

 well, except that of Quélet (Flore Mycologique). But Quélet 

 is said (by Boudier in Bull. Soc. Myc. Fr. 1902) to have con- 

 founded the two species]. 



10 a. A. aspera Quel. (Fr. ?). 



Spores broadly ovate, 9 x 6V 4 H- 



Fig. specim.: Hjallese, mixed foliaceous wood, Sept. 1897 

 (and 1900). Very much like the preceding species, but easily 

 distinguished by the at first pale sulphur-yellow universal veil 

 (warts on cap, on edge of ring and at base of stem). The flesh 

 just under the cuticle is also pale yellowish. — While the 

 specimens figured had a pallid grayish-brown cap, I have also 

 met other colour-forms, f. inst.: 



Forma fusca, with a dark fuscous cap. (Spores 8 — 9 x 7 u; 

 cells on edge of gills about 18 u. Lundeborg, wood of Fagus 

 Aug. 1914) and 



10 b. var. Francheti Boud. 



Spores 9 x 6 — 67 2 M, cells on edge of gills 20 — 24 u diam. Cap 

 almost whitish, central part slightly yellowish. 



Fig. specim.: Hjallese, mixed foliaceous wood, Julv 1903 

 (and 1914). 



[A. aspera (sensu Fries) seems to be the fuscous form men- 

 tioned above]. 



11. A. rubescens (Pers.). 



Spores oval-ovate, 8 — 9 x 5 — 5 1 /.,. 



Fig. specim.: Hjallese, foliaceous wood, Sept. 1897 and Aug. 

 1900. Very common, as well in foliaceous as coniferous woods, 

 till late in the autumn.
