is met with in Pistulina hepatica, Fr., which is generally found on old Oaks; it is, 

 however, somewhat common on Beech in Epping Forest, and I have gathered 

 it in fine condition from the Ash. It has also been met with on the Walnut 

 and Chestnut. 



Sometimes the special habitat of Fungi found on trees is the principal 

 character. This is the case in Eadulum querciuum, Fr., and Eadulum fagincum, 

 Fr., one plant differs very slightly from the other in specific characters, but one 

 is peculiar to the Oak, and the other to the Beech. 



In the following list it will be understood that the enumeration of Fungi 

 peculiar to certain trees, includes also the stumps and branches of the same 

 tree, as well as old rails, and squared timber made from it. 



It must not, however, be supposed that because Blarasmius cgiphyllus, Fr., 

 for example is given under "Ash petioles," that the species is never found 

 elsewhere, but that it is its usual and common habitat. The same remark applies 

 to many other species which are almost peculiar to certain trees. All the 

 species here given are Hymenomycetous, except two truffles. 



A few species, from their peculiar habits, should find a place in this list, 

 as the Fungi generally found on walls and ceilings, as Agaricus muralis, Sow., 

 Coprinus radians, Fr., Tulostoma mammosum, Fr., Peziza domestica. Sow., and 

 P. Piggotii, B. and Br. On sawdust, as Agaricus petasites, Fr., A. cucumis, P., 

 Paxillus Panuoides, Fr., Sphccrobolus stellatus, Tode, &c. On chips, as Agaricus 

 furfuraceus, P. ; and many others. On chestnut husks, as Peziza echinophilia, 

 Bull. ; and on fallen catkins, as Peziza caucus, Reb. 



The names of the microscopic Fungi affecting the leaves and twigs of trees 

 and the long list of species found on old stumps and rotten branches in general 

 are omitted from the appended list, for the reason that they would teach nothing 

 and be of no help in the determinations of species. 



For further particulars as to the several Fungi, recourse must be had to 

 Berkeley's "Outlines," or the more recently published "Handbook" of Mr. 

 Cooke's.
