302 TRANSACTIONS OF THE [Sess. lxxxii 



How this fungus, which seems to require warmer con- 

 ditions than are to be found in Britain, appeared in Argyll 

 I cannot explain. Spores may have been brought north 

 among the roots of some imported plant, but I did not 

 notice any such growing in the neighbourhood. It appeared 

 to me that the occurrence of this rare fungus in Scotland 

 was worthy of being noted by the Botanical Society. 



I may add that I found at Kilmelford this autumn a 

 good many specimens of Clavaria aurea, Schaetf., and of 

 Clavaria botrytis, P. — both rare in Britain. 



A New Grass, Koeleria advena, Stapf. 

 By James Fraser. 



For the name of a new grass belonging to the genus 

 Koeleria, and for its description by Dr. Stapf, I am indebted 

 to the Director of the Royal Botanic Gardens at Kew. 



This grass I found in July 191G, in the neighbourhood 

 of Edinburgh, growing among surroundings and under con- 

 ditions which indicate that its seeds must have been intro- 

 duced into this countrj'' along with esparto grass, from the 

 east of Spain or the north-west of Africa. 



Two or three specimens have been retained at the Kew 

 herbarium. 



Dr. Stapf's description is as follows: — 



Koeleria advena, Stapf (sp. nov.).

 vel minute emarginatis (hand acuminatis biaristulatis)
