The list of 2626 species is compiled from over 16,700 

 records, and is arranged under the five county divisions, or 

 vice-counties, employed by II. C. Watson in " Cybele 

 Britannica," viz.: — 61, South-east Yorks.; 62, North-east 

 Yorks.; 63, South-west Yorks.; 64, Mid-west Yorks.; 65, 

 North-west Yorks. The records are quoted in the order of 

 priority of date of first record, hence the divisions do not 

 follow a fixed sequence. 



The number of records for each vice-countv is as follows: — 

 S.W. Mm W. X.W. N.E. S.E. 



7912. 2369. 1 188. 4018. 1226. 



While every care has been taken to include all reliable 

 records, many considered to be of a doubtful nature have 

 been excluded. Others, as Zasmidinm ccllarc Fr. ; Anthiua 

 Hammuhi Fr. ; Octoma vin'dis Rabh. ; etc., now known to be 

 nothing more than sterile mycelium, have been altogether 

 omitted. Others, as Tvichoderma viride Pers. ; Sepedoninm 

 chrysosperiiiitm Fr. ; Bispora monilioides Corda, and a few more 

 of the group Ilypliotiiycftfs, now looked upon as conidial 

 conditions of higher forms, have been printed in small 

 capitals within square brackets [ ] and have not been 

 numbered. 



The paucity of information respecting the numbers and 

 distribution of other counties renders comparative tables 

 meaningless. The only other countv whose Mycological
