Fig. specim. : Hjallese, copsewood (Corylus etc.) Oct. 1898. 



This little species, which is rather common in similar localites, 

 differs somewhat from the current description of I. descissa. In 

 my plant the stem is not hollow, the gills are adfixed and the 

 fibrils of thr distinctly rimose cuticle are rather dark brown. 



23. I. microspora n. sp. Plate III fig. 8. 



Spores 6 l / t — 7 X 4— 4 1 /* u, obliquely ovate. Cystidia : a) obtusely 

 fusoid-bottleshaped , about 14 u broad, muriculate; b) small, 

 obtuse. 



Fig specim.: »Bleget« and »Frueskov» near Egeskov, gregarious 

 in foliaeeous wood, Sept. 1916. Also met with in other similar 

 localities. 



Pileo 1,2 — 1,S cm, primitus subconico, dein explanato et minute 

 umbonato, pollute fusco-brunneo (centro obscuriore), primitus lævigato 

 dein mor gine fibrilloso-subrimoso ; stipite æquoli, globro nec pruinoto 

 sed opice leviter flocculoso, 3— 4 cm X n/ 2 —3 mm, primitus pollido 

 dein brunneo-pollido, subfistuloso; lomellis pollide fusco-cinnamomeis 

 adnexis ; odore nullo. 



Smaller and paler than no 22, and not distinctly rimose.

24. I. Bongardii (Weinm ) Fr. 



Spores ovato-ellipsoid, 13 X 6 1 /* H- Cystidia (on edge) crowded, 

 obtuselv cvlindric-elubshaped, about 10 fa broad. 



f ap 3__5 cnii obtusely umbonate, fibrillose-squamose, scales 

 ochraceous-brown, towards the edge entirely split up into fibrils. 

 Stem rather long, somewhat wavy, tibrillose, apex slightly mealy. 

 Edge of gills white. All parts of the mushroom become flushed 

 with incarnate when bruised or cut. 



The large spores and clubshaped cystidia distinguish this species 

 from all other pvriodorous species. The figure of Fries (Icon, 

 sei. II 107 1-2 ) gives a very good idea of the habit of this species. 

 As to the / Bongardii of Cooke and Massee vide no. 4.

25. I. calamistrata Fr. 



Spores oblong-oval, IOV2 — 12 X ö 1 /,, u. Cystidia inflated clubshaped, 

 12— 18 u broad. Fig. specim.: Hjallese, on naked, clayey ground 

 under Alnus and Fagus, Sept. 1912. 



This is the slender form figured by Fries (Icones sei. 106 s ). 

 The cap is only about 2 cm, the stem 5 cm x 3 mm. The base 

 of the stem is clad with a whitish, often somewhat bluish-green 

 tomentum (not so dark as figured by Fries).
