Mycologia 



The type was collected by William Falconer. Peck had specimens 

 also from northern New York, New Jersey, Michigan, and the 

 District of Columbia. Dr. KaufTman has made a special study of 

 it in Michigan and pronounces it the largest species of the genus in 

 his state. When growing on compost, it naturally attains larger 

 proportions than when growing wild in the woods. I have speci- 

 mens from Long Island six inches broad ; and I found a cluster in 

 Tennessee under red cedars in a pasture composed of individual 

 plants five inches broad and six inches high. 



Doubtful and Excluded Species 



Agaricus Achimenes Berk. & Curt. Ann. Mag. Nat. Hist. II. I : 

 98. 1849. Described from South Carolina and also reported 

 from North Carolina. I saw a portion of the type at Upsala, but 

 did not make full notes on it ; so I have asked Miss Wakefield to 

 describe the specimens at Kew, which she has very kindly done 

 as follows : 



" There are three specimens of tfiis. The largest, from which the spores 

 drawn were taken, has a pileus measuring 9 cm. across. The other two are 

 4 and 5 cm. The pileus is slightly umbonate. The stalk varies from about 

 7 to 9 cm. in length. It is 7-8 mm. thick above, and becomes gradually thicker 

 towards the base. A well-marked ring, with entire edge, occurs about one 

 third of the distance from the apex. The base of the stem has some whitish 

 mycelium adhering to it. The gills are very crowded, and appear to have 

 been either free or adnexed. They are lightish-brown in colour. Spores pale- 

 yellowish by transmitted light, apiculate, 11-12x8 //,, and with a blunt apex 

 such as one often sees in Coprinus spores, as if there were a regular germ- 

 pore there. The plant is surely a Pholiota." 



Agaricus amygdalinus M. A. Curt. Gard. Chron. 34: 1066. 

 1869. Curtis did not describe the plant, but said it could be recog- 

 nized at once by its taste and odor of bitter almonds. According 

 to him, it occurred commonly in North Carolina among leaves in 

 rich woods, etc. See A. fabaceus. Other species of Agaricus are 

 now known to have an almond flavor. 



Agaricus cretaceus Fries, Syst. Myc. 1 : 280. 1821 ; not A. cre- 

 taceus Bull. 1787. Described from plants found in manured 

 fields in Sweden. Reported from North Carolina, Minnesota, and 

 California by the older collectors. Peck mentioned it in his 22d 

 Report, and there is a specimen in his collection from West Albany
