NOTES ON RARE VICTORIAN FUNGI.

Cyttaria Gunnii (Berkeley). 

 This fungus formerly only known from Tasmania, and con- 

 fined in its growth to our evergreen beech, Fagus Cunning- 

 hami, has just been discovered in the beech forests towards 

 Cape Otway by Mr. R. Lucas, whose attention was directed to 

 the likelihood of its occurring there. It resembles somewhat 

 a raspberry, but is of yellowish colour. Cyttarias distinct from 

 ours occur on the beeches of South America, and are eaten 

 there by the aboriginal tribes ; but probably they should be 

 prepared in some way to render them more palatable, and 

 absolutely harmless. It was first rendered known here through 

 Mr. Dall that a Cyttaria also occurs on the beeches of New 

 Zealand, but the species there was late last year described by 

 Mr. W. Buchanan. 



Cordyceps Taylori (Berkeley). 

 This species grows from the head of a large grub. It was 

 discovered first on the Murrumbidgee, and latterly specimens 

 vrere also obtained from the vicinity of Geran gamete by Mr. 

 John Price, and Mr. H. Carr. This Cordyceps branches out 

 almost in a hart's-horn fashion, and is thus very different to the 

 far more common C. Gunnii, which is simply club-shaped. 

 Indeed if it were not for anatomic similarity the two would not 

 be considered congeneric.
