UEETFORDSniEE NATURAL HISTOEY SOCIETr. XXXV 



Field ^Meeting, 4Tn November, 1882. 

 CASSIOBURY TAEK, WATFORD. 



Until the present occasion all the Ficlcl Meetings of the Society 

 have boon held (luring the later spring or carliei- summer months, 

 from near the end of April to about the middle of July. Some of 

 these meetings have been devoted entirely to botanical investigation, 

 and at most of them the collection and identification of plants has 

 formed a prominent feature. Eut, with a few exceptions, these 

 have been flowering plants and ferns only, the time of the year not 

 having been that at which the greater number of cryptogamic plants 

 are met with. 



In walking through Cassiobury Park in the early part of October, 

 the writer of this report was struck with the number and variety 

 of the larger fungi growing in certain parts of the park, and, after 

 some correspondence with the eminent cryptogamic botanist Dr. M. 

 C. Cooke, an Honorary Member of the Society, who kindly con- 

 sented to take part in a "Fungus Foray," and to name any fungi 

 met with, the present meeting was announced. 



A few of the members of the Society assembled at the principal 

 entrance to Cassiobury Park at half-past two, meeting here Dr. M. 

 C. Cooke and Mr. H. T. "WTiarton. After collecting several species 

 of fungi near the entrance, the party went direct across the park by 

 the road over the river and canal, and, through the avenue beyond, 

 to the low ground, mostly overshadowed by trees, which extends 

 from Whippendale, by the side of Rouse Barn Lane, to the water- 

 cress beds near Cassio Bridge. From this part of the park most of 

 the species of fungi and mosses collected were obtained. The park 

 was left at the point where Bouse Barn Lane crosses the canal, and 

 the party returned to AYatford by the high road from Cassio Bridge. 



Appended is a list of the fungi collected, identified by Dr. Cooke 

 and Mr. Wharton, which is of special interest as being the first 

 published list for any part of the county of Hertford ; and also a 

 list of the mosses identified by Mr, A. E. Gibbs, the only previous 

 county list of this tribe of plants being that given, without locali- 

 ties, in an Appendix to the ' Flora Hertfordiensis.'
