COSTA HI CAN AGARICACEAE 
Carroll «7. Dodge 
The first collection of Costa Rican Agaricaceae of which records 
have survived, was that of Anders S. Oersted who visited Costa Rica, 
1 Nicaragua and the Virgin Islands in 1846-1843.

I Upon his return to Denmark, he apparently turned over his collections 
land a duplicate set of water-color paintings to Elias Pries for naming, 
since the form the greater part of the Agaricaceae treated in his "Novae 
■Symbolae Mycologicae published in 1851. No specimens have survived at 
Uppsala, although Pries mentions alcoholic material in alcohol. The 
collection of drawings, mostly on sheets x cm, usually with Agaricus 
and a number written across the top in what may be Oersted's handwriting. 
|The number corresponds to that cited by Pries. Below the drawing, the 
name given by Pries appears, usually in a handwriting anparently that of 
Pries in his later years. At the bottom of the sheets are the data: 
Costa Rica . A. S . Oersted in the handwriting of T. M. Pries. This latter 
was probably added when the collection was tistributed in the general 
Priesian collection of drawings which were arranged by genera in port- 
folios in the early 1880' s. Since many of the species cited are not from 
Costa Rica, the data given in the Novae Symbolae should be considered 
correct and not the locality given on the sheet. All of the species but 
one in which Pries mentions a drawing are present, along wiht some drawings 
of some fungi which are not determinable in the absence of specimens.
