16 I. deglubens Fr. 



Spores obliquely ovate, 9 >< 5 u. Cyslidia on edge: a) bladder- 

 shaped, short, 10 — 14 u broad, b) fusoid, protruding, muriculate. 



Fig. specim.: Hesselager (> Skelmose«), in wood of Abies, Oct. 

 1906 — and in several other coniferous woods, generali}' gre- 

 garious. 



Cap at firs,t innately fibrillose-tomentose , then more or less 

 cracked-squamulose, dingy brownish, at last darker, almost date- 

 brown. Stem pallid, with a tinge of brownish, apex somewhat 

 white-plumulose or powdered, minutely downy-fibrillose towards 

 the base. — My plant is never »obscure furfurata< on top of 

 stem, and probably comes nearest to Karsten's var. trivialis. 



17. I. cæsariata Fr. var. 



Spores 7 — 8 X 4 1 /, — 5 u, ovate or ellipsoid. Cystidia scattered, their 

 protruding part cylindric-bottleshaped, muriculate or not. 



Fig. specim.: Hjallese, on moist ground (Spiræa Ulmaria etc.) 

 in foliaceous wood, Aug. 1904. Also found in some other simi- 

 lar localities. 



Cap somewhat convex, um bona te, then expanded-umbonate, 

 covered (except about the umbo) with brownish-yellow fibrils, 

 which at last form small fibrillose squamules. Stem at first 

 minutely powdered, then smooth, slightly striate. Gills at first 

 whitish, then dingy brownish with a tinge of yellow. — Perhaps 

 too closely related to /. hirtella. — Cooke's figure shows an al- 

 most chestnut-brown, scaly fungus, very different from mine. 



18. I. hirtella Bres. 



Spores ovate, 9 x /2 x ; "> u - Cystidia on edge: a) bottleshaped, muri- 

 culate, b) inflated, obtuse. 



Fig. specim.: Fruens Bøge in grass on roadside in foliaceous 

 wood, Aug. 1907. Also found in other similar localities, espe- 

 cially under Corylus. 



Cap l x / 4 x 2 cm, somewhat conic, at last expanded and slightly 

 umbonate, towards the edge fibrillose and at last slightly rimose, 

 but for the rest set with small fibrillose squamules, central part 

 brownish-yellow, edge paler. Stem minutely striate-sulcate, velvety- 

 pruinose (i. e. clad with cystidia like those on the gills), pallid 

 ochraceous-yellowish. Gills rather distant, adnate, pallid with a 

 tinge of yellow (edge pale), when ripe yellowish-cinnamon. It 

 has a very faint smell (of peach-leaves or bitter almonds). 



19. I. posterula Britz, ex Sacc. Plate III, fig. 6 



Spores broadly ovate, 7% — 8 x 4 3 / 4 — 5u Cystidia fusoid, muri- 

 culate, about 10 — 12 u broad. 



Fig. specim : Aarup, in wood of Pinus and Picea, Sept. 191(5. 



Cap 3 — 5 cm, at first somewhat campanulate, then expanded,
