Historical Introduction. — While an enumeration of the species of all 

 other groups of plants found in Ireland has at some time or other been made, 

 this has never been attempted in the case of Fungi ; and yet the group 

 embraces by far the largest section of the Flora as regards number of species, 

 and, moreover, is of great importance from an economic point of view. 



Still it would not be correct to assume that the study of Irish Fungi has 

 been neglected. A reference to the Bibliography at the end will show that 

 a very considerable amount of attention has been devoted to the group. 

 But much still remains to be done; and it is verj' probable that we are 

 at present acquainted with not more than half the number of species which 

 will ultimately be found to be natives of this country. 



Threlkeld, in his " Synopsis Stirpium Hibemicarum," published in 1726, 

 mentions the names of sixteen species of Fungi found in Ireland ; but no 

 descriptions or localities are given. In the Appendix to the above work 

 three additional species are mentioned. 



The next reference to Irish Fungi occurs in " The Antient and Present 

 State of the County of Down," published in 1744, where four species are 

 described as having been found in that county. 



Rutty's "Natural History of County Dublin," published in 1772, 

 mentions two species of Fungi, one of these being the Truffle in County 

 Meath.
