NOTES ON BEISTOL FUNGI. 293 



Another excursion may be mentioned which will reward the 

 mycologist if he be in luck. It is to the wood on the Pennant 

 rock, extending from Hanham to Conham on the Avon. The 

 train may be taken to Keynsham, whence a short walk leads to 

 the Hanham ferry, and about half a mile further, on returning 

 towards Bristol, the ground to be searched commences by some 

 heathy spots and old quarries. Several of the red Fezi%(& occur 

 on the slopes ; on the wet sides of the quarries some good Algae, 

 such as Cosmaria, occur ; on the flat heath above the curious 

 little Ifarasmius impudicus, Pr., may be found, — where also the 

 beautiful Agaricus (SygropliorusJ calyptrceformis, B., used to be 

 plentiful, but the habitat has been almost destroyed to grow 

 potatoes, an attempt which seems to be a failure, as the ground 

 is returning to its former condition ; in the woods further on the 

 rare Strohylomyces strolilaceus, B., was found, two or three years 

 ago, on a spot which had been searched over by mycologists for 

 many years, but this fungus had never been seen there before. 

 This fact shows the difficulty of ascertaining the extent of the 

 mycological flora of a neighbourhood. The exceptional appear- 

 ance of a species, however, holds out hopes to the cryptogamic 

 botanist of alighting on new forms when least expected, which 

 can hardly occur to those who confine their attention to the 

 higher vegetables. 



Hanham Woods have yielded several rarities among the more 

 obscure tribes, Fachjplilcem citrinus, B., P. conglomeratus, B., the 

 only habitat known in Great Britain ; Sph(Brosoma ostiolatum, 

 KL, Ge7iea Jiispidula, B., Tuher puheruhm, B , often infested 

 with the parasitic Hypocrea indusa, Br., Tuher dryopliilum, TuL, 

 and Boletus parsiticus, Bull., may be mentioned among the 

 rarities. Having thus pointed out some of the best excursions 

 for the mycologist, we will now present a short list of the species 

 which have been met with and determined in the district. 



Mr. H. 0. Stephens was, perhaps, the first person who paid 

 much attention to the mycology of the neighbourhood of Bristol, 

 but he laboured under so many disadvantages in regard to the
