odour characteristic of natural spawn, and when placed in a 
mushroom-bed grows and produces mushrooms normally. The 
advantages of this method are : — 
I. — The production of a pure mycelium , free from the many 
diseases, the germs of which are introduced along with the spawn as 
at present produced. 
II. — Choice . of varieties. It is well known that certain varieties, 
especially the'one having the cap entirely white, is most esteemed 
in the market. By the method described it is alone possible to 
perpetuate any variety in a pure state. 
III. — Permanent production of spawn. At present the produc- 
tion of spawn is intermittent ; by the culture process spawn can be 
produced throughout the year, an evident advantage. 
The authors hope to apply the same method of cultivation to 
other edible species of fungi, as the Morel, Boletus, etc.

In the present paper two species of fungi are described and 
accompanied by good coloured figures. The first is Hygrophorus 
Marzuolus (Fr.), Bres., the old Agaricus Marzuolus , Fries, Syst. 
Myc., i., p. 84, and Hym. Eur., p. 93. The second species is as 
follows : — 
Odontia Pirottae, Bres . — Subiculum broadly effused, membra- 
naceous, ivhite, seceding, preceded by rhizomorpoid strands, margin 
himantoid; spines terete, 1J-2 m.m. long, apex pruinately fim- 
briated, bright golden-orange ; spores ovoid, straw-colour (sub 
micr.), 4^-5 x 3^ p ; basidia clavate, 20-25 x 5-6 p ; subhymenial 
hvphas hyaline, septate, 3 p thick.

The foregoing general summary of the objects of the work will, 
it is to be hoped, enable the reader to understand the details which 
will now be taken up. 
[Lack of space forbids giving in detail the results of numerous 
careful experiments conducted in various widely separated districts, 
also the tables giving results following different modes of treat- 
ment, kind and strength of fungicide used, method of application, 
etc. The summary, however, is given, showing the general out- 
come of the experiments.]
