Peradeniya is in the wet zone (Central Province) at an 

 elevation of 1,560 feet; Matale is in the wet zone (Central 

 Province) at 1,200 feet. The agaric has also been found at 

 Badulla in the Eastern wet zone (Uva Province) at 2,220 

 feet, at Telulla (Uva Province) below 100 feet, at Undugoda 

 fS;iharagarauwa) at 800 feet, and at Trincomalee (Eastern 

 Province) at sea level, while Mr. E. E. Green informs me that 

 it is common in Pundalu-oya at 4,000-4,300 feet. 



The Armillaria form occurred only on September 18th— 19th 

 and October 12th : in the first instance seventeen were found 

 in a very small area. At Matale, March 0th, 1900, I was 

 informed that in addition to the Pluteus form then collected, 

 the coolies ate an ; ' egg-shaped " mushroom, i.e. the Armillaria 

 form. It was at first thought that the difference in these two 

 Forme waa due to the difference in depth of the combs from 

 which they a cose, but the Pluteus form has since been found 

 growing from a comb only 1<> centimetres below the surface. 

 The product ion <>f the ringed form may depend on the humidity 

 df the comb chamber, but observations are not yet numerous 

 enough to afford any solution <>f this question. 



I have not been able to germinate the spores of the agaric 

 in .■ 1 1 1 \ solution, nor has the addition of pieces of the tissue to 

 tin- banging drops containing the spores induced any growth. 

 Experiments with portions of the developing agaric on various 

 media <ti<i not result in the production of any myeeiium. bul
