The small collection of Agarics from Koh Chang, admirably 

 preserved and accompanied by notes, thus rendering identification 

 possible , has extended the geographical range of several species, 

 in addition to furnishing several new forms, all belonging to existing 

 genera. The most interesting novelty is Favolns albidus a species 

 evidently allied to Favolus sprucei Berk., from Brazil.
