TECHNICAL WORKS. 
Of these there are a very large number, of which the following are most 
available: 
British Fungi (Ilymenomycetes), by Rev. John Stevenson; a 
systematic work in two volumes, and a fairly trustworthy guide in the 
determination of species. $8.06. 
British Fungus Flora, by George Massee; a systematic work in 
four volumes, of which the last treats of the Ascomycetes, is more com¬ 
plete than Stevenson, and with fuller descriptions, although not so 
accurately done. The first three volumes are all that are necessary for 
students of the Basidiomycetes. Many find this more useful than 
Stevenson. Per vol., $2.00. 
Clavis Agaricinorum, by W. G. Smith, 40 pp., 6 plates, contains de¬ 
scriptions of families and genera; appended are figures to show the 
structure and relationship of the genera, according to Fries, of the 
Agarics proper; there is a key to genera, and a list of British Agarics 
known at the time (1870). 75 cts. 
A Manual of the British Discomycetes, by William Phillips, is 
a standard systematic treatment of the Pezizas, Morels, Ilelvellas, and 
and related fungi. It covers the ground of Massee’s fourth volume. 
One or the other is necessary for students of this group. It is well 
illustrated. $1-50.
