At one time we thought our species might be Russula 

 periglypta, B. and Br., of Ceylon. Through the kindness of 

 Mr. T. Petch, of Peradeniya Gardens, Ceylon, we have 

 received coloured drawings and dried specimens of the Ceylon 

 species which show that the two are clearly distinct. 



As indicated under Clitocybe paraditopa (No. 100), it is 

 hoped that a coloured figure of this species, the plate of which 

 has been prepared for several years, will be published in the 

 Agricultural Gazette of N.S/ Wales in 1920.

119. Collybia radicata, Relh. (Syn. C. eradicata, Kalch. ; 

 C. olivaceo-alba, Cke. and Mass.). — The typical form is 

 recorded by Cooke (No. 78) for Victoria, Queensland, Tas- 

 mania, and Western Australia. C . eradicata (Cooke, No. 79) 

 is recorded for New South Wales and Victoria ; as it differs 

 from C . radicata only in the stem not being rooting and not 

 being thickened at the base, we adopt Cooke's suggestion 

 that it may be possibly only an accidental variety of the 

 latter, and so sink C. eradicata as a synonym. C. olivaceo- 

 alba is recorded in Cooke (No. 82), and for Kogarah, New 

 South Wales, by R. T. Baker (Proc. Linn. Soc. N.S. Wales, 

 xxiv. (1899), p. 446) for Victoria and South Australia. From
