SYSTEMATIC AND FLORISTIC NOTES. 



A. RADICOSI (QUÉLET). 

 a. SCORTEI (FR. ext.). 



1. M. urens (Bull.) (M. peronatus Bolt.) 



Spores 9 x 3 3 / 4 ju, pipshaped-lanceolate. Cystidia crowded, short, 

 cylindric. 



Fig. specimens: Hjallese, in wood of Fagus, Aug. 1896. Com- 

 mon in woods amongst foliage (also in coniferous woods). 



This species varies a good deal in colour (from pallid to dingy 

 rufous wood-colour. The base of the stem is more or less pero- 

 nate. But like Schroeter and other authors I can see no suffi- 

 cient reason for distinguishing two species (M. urens and M. 

 peronatus). — Saccardo gives for M. urens the spore-measure 

 3—4 x 2 1 / s — 3 u, for peronatus 6—8 x 3—5 u; MASSEEhas8x4 u 

 and 10 x 6 — 7 |a respectively But I have never observed either 

 the very small or the very large spores in any specimens. 



2. M. fuscopurpureus (Pers.) 



Spores 6V2 — 8 x 3 — 3 l / 2 , pipshaped-lanceolate. Basidia with very 

 long sterigms (8 u). 



Fig. specimens: Hjallese, wood of Fagus, Oct. 1895 and 1909 

 (young). Fries places this species in Tergini, but its natural 

 position is next to M. urens He describes the strigose coating 

 at the base as »rubiginous«; but it is generally dingy ochraceous- 

 pallid. When young the whole plant is much lighter in colour 

 (pale gilvous-ochraceous), the edge minutely striate. This to my 

 mind is probably M. terginus Fr. 



3. M. putillus Fr. 



Spores 9 x 3 3 / 4 u, pipshaped-lanceolate. 



Fig. specimens: Håre Bjerge, rather numerous, rooting in a 

 deep layer of Pinus montana-needles, Oct. 1906. Also found at 

 Arup, Oct. 1911, in wood of Pinus silvestris. 



4. M. Oreades (Bolt.) 



Spores 9V 9 — IOV2 x BVi - " 6 H> broadly pipshaped. 



Fig. specimens: Fruens Bøge, old grassfield, border of road,
