NOTES ON AUSTRALIAN FUNGI. 543 



by Cooke (I.e.) from Queensland, South Australia, North 

 JSast Australia and Gape York. In the National Herbarium 

 there are specimens from the following localities: — Hill 

 Top and Hazelbrook (J. H. Maiden, 1903 and 1906) on Coach - 

 wood (Ceratopetalum apetalum); Pittwater (A. Maclellan, 

 September, 1907); Helensburgh (W. Oraigie, August, 1909); 

 Hornsby and Lilyvale (A. A, Hamilton, October, 1910); 

 Willoughby (A, G, Hamilton, July, 1910); Grose Vale, (Miss 

 Campbell, September, 1912, determined by Lloyd). We 

 have also specimens from Mount Wilson and from the 

 Hawkesbury River, both taken in June, The shed spores of 

 New South Wales plants are elongated, sausage-shaped, 

 granular, 13*8 to 15*5 x 5/*. 



160. Hexagona tenuis var. umbrinella Pr. 

 Lloyd (Letter 63, 1916) has identified for us as H. um- 

 brinella, specimens from Helensburgh (A. A. Hamilton, 

 October, 1913). He considers H. umbrinella as a form of 

 H. tenuis with a dark reddish-brown rugulose surface. 



161. Hexagona tenuis var. subtenuis Berk. 

 Cooke, Handb. Aust. Fungi, No. 891; Baker, Proc. Linn. 



Soc. N.S.W., xxii, p. 238, 1897. 



This, according to Lloyd (Syn. Gen. Hexagona, p. 26), 

 * was originally named by Berkeley from India.' The 

 Australian specimens recorded under this name are very 

 probably intermediate forms between H. tenuis and H. 

 rigida. 



The following are probably thick forms of Hexagona 

 tenuis, and may be H. subtenuis of Berkeley. On silky 

 oak (Grevillea robusta) Hyde Park and Botanic Gardens
