Tricholomataceae 

 Marasmius Schultesii Singer in Fl. Neotrop. 17 (1976) 131. 



Colomhia: Comisaria del Amazonas-Vaupes, Rio Apaporis, Soratama 

 (between Rios Pacoa and Kananari). July 3, 1951. Schultes el Cabrera 12869. 



This tiny mushroom, growing saprophytically on roots in 

 upland forest above the flood level, is the only fungus that I ever 

 collected in the northwest Amazon for its presumed medicinal 

 use. It is not common, but where it occurs it seems to grow in 

 relatively large patches. The Taiwano Indians of the region 

 gather several handfuls and, after drying it in the sun, reduce it 

 to a powder which is put into the ear to treat cases of fungal 

 infection of the ear-drum. The powder is applied in the evening 

 and must be washed out each morning. Several days of the 

 treatment, according to the only Indian from whom this use was 

 ascertained, are said to be sufficient to relieve this frequent 

 ailment and to restore normal hearing and balance. 



The Taiwano name for mushrooms in general is e-kee'. This 

 species is known as ta-te-e-kee'. 



Palmae 



Mauritiella sp. 



Colombia: Comisaria del Amazonas, Rio Apaporis, Soratoma. "In clumps, 

 5-10 together. Stems devoid of spines. Fruit ripens brown, smaller than usual 

 species." June 21, 1951. Schultes et Cabrera 12792. 



The fruits of this palm provide an oil which the local Indians 

 employ to treat fungal infections of the skin. The oil is 

 frequently utilized as a vehicle of other drug plants.
