8. M. scorodonius Fr. (A/, alliatus Schaeff.) 



Spores 7 — 8 x 3 x / 2 — 4 y. pipshaped. 



Fig. specimens: Arup, on tufts of grass in plantation, Sept. 

 1899. — Common, chiefly on grass but also on twigs of Calluna, 

 Picea etc. (especially on sandy land). 



9. M. prasiosmus Fr. 



Spores 9 x 5 u. pipshaped. (Another find: 8 x 4 1 /-, — 5 u). 



Fig. specimens: Hjallese, in wood, attached to dead leaves of 

 Quercus, Oct. 1985. Rather rare, chiefly on oak-leaves but also 

 found in wood of Fagus. 



My plant is almost intermediate between the descriptions of 

 M. prasiosmus and M. porreus (Pers.). On account of the persi- 

 stent smell, the rather crowded and thin gills etc. I refer it to 

 M. prasiosmus. The stem is minutely powdery-pubescent above 

 and densely clad with a bay-brown velvety coating below, which 

 dilates on the leaf on which it grows. According to Massee 

 the spores of M. piasiosmus are 14 — 15 x 7 u (those of M. por- 

 reus subglobose, 4 u in diameter). According to Ricken they 

 are 7 x 4 u-, while Bataille has 8 — 11 x 4 — 5 u. 



10. M. alliaceus (Jacq.) 



Spores 10 — ll 1 / 2 x 6'/ 2 — 7 p, ovale. Cystidia on edge crowded, 

 inflated-cylindric or subfusiform, about 11 /a broad. The coating 

 of the stem is made up of hyaline, cylindric, obtuse, 6 — 9 u 

 broad hairs. 



Fig. specimens: Grib skov, (wood of Fagus), Sept. 1896. Com- 

 mon. The root springs from buried sticks or branches (always 

 of Fagus). 



10 a. M. alliaceus var. subtilis (now var.) 



Spores 10 x 6 1 / 2 \i, broadly ellipsoid-ovate. Cystidia obtuse, cy- 

 lindric-hairshaped or slightly ventricose, 6 — 8 ju broad. Hairs on 

 stem scattered, short, erect. 



Fig. specimens: Ry, on the ground under old Fagus, in wood, 

 Aug. 1902. (Also found at »Fruens Bøge« Aug. 1916, similar 

 locality.) 



Cap 3— 4*/s mm, convex, pellucido-striate, pallid fuscous. Stem 

 setaceous, rooting, 3 — 4 cm high, 0,4 mm broad, fuscous, apex 

 whitish, ptuinale. Gills free, distant, broad, ventricose, dingy 

 whitish. — Although this little tiny plant at first sight not at 

 all reminds you of M. alliaceus I do not think it deserves spe- 

 cific rank. 



B. RAMEALI. 



11 M. foetidus (Sow.) 



Spores 87 2 — 10 x 3 3 / 4 — 4 u, lanceolate-ellipsoid, somewhat flatte- 

 ned on one side.
