when moist, but it is always recognisable by the pink colour 

 of the fresh spores. Throughout the whole of October last year 

 it could be gathered in the same spot, until the beginning of 

 November when it became attacked by mould. 



82. Dictydium cancellatum Macbr. does not feed only on 

 pine wood, though it is most often found there. It is of 

 earlier appearance than the last species. In June it was found 

 forming-up on an old alder log, supporting a melon frame. I was 

 informed that the log had lain in the same spot exposed to the 

 weather for over twenty years. In July, after much rain, it 

 appeared on pine, in August on poplar, in September on beech, 

 and in October it stretched like a carpet for several square 

 feet over sawdust on the ground. The plasmodium, when about 

 to fruit, was subjected to heavy rains, and irregular, though 

 persistent, cups were formed of a beautiful transparent purple, 

 resembling in colour the "Blue John" of Derbyshire. 



var. fuscum Lister occurred on pine wood during a remark- 

 ably mild December in 1918. 



183. Licea flexuosa Pers. Every month from September to 

 March this frequent species can be met with on moist coniferous 

 wood. Sometimes the sporangial wall is clean, translucent and 

 glossy but more often it is enveloped in a coating of dark refuse 

 matter. It thrives particularly well on old pine sawdust, where 

 I have seen it covering several square yards in close snake-like 

 masses, folding about and blackening the soil. 



184. Licea pusilla Schrad. This minute and most inconspicuous 

 species was first recorded for the county in October 1912, on 

 St George's Hills, Weybridge. In November ten years later 

 it was again found in that neighbourhood, on the same piece 

 of naked pine bark as two other members of the same genus, 

 viz. L. minima and L. flexuosa. The sporangium wall under 

 a pocket lens frequently appears merely dull black and so faith- 

 fully agrees with the colour of the surrounding habitat as to 

 produce a very effective camouflage. The spores were often 

 only I4ju,, sometimes 16 ju, and more. 



85. Licea minima Fr. is not unfrequent wherever there 

 are pines. I first noticed it in September on dead Merulius 

 that had spread over a disintegrating pine log. The sporangial 

 wall was deep purple brown, nearly black. In the following 

 April a form with light brown sporangia was found near 

 Hanscombe, the plasmodic granules on the border being almost 

 colourless or wanting. In October and November last year, 

 this species was very plentiful on old pine fencing lying on the 

 ground. 



86. Tubifera ferruginosa Gmel. It is not generally known that 

 the Plasmodium of this species may sometimes be white or
