Abstract
Primary and secondary, várzea forests, do not contain any ectotroph elements, in contrast to terra firme forests, campina and related forest types, and igapós. The periodically inundated forest of Central Amazonia, and particularly the várzea forest, presents four main types of adaptation of macromycetes to the ambiance. These are described and exemplified. Lists of Higher Basidiomycetes of
várzea stands from different localities of Amazonia and with relation to rainy season and inundation level are given. In a typical March aspect, Janauaria arnazonensis and Collybia phylladophiloides are
F(ruiting) dominants among the litter and soil fungi. In spite of still insufficient exploration of the ecology of inundated forests in the Upper and Lower Amazonas - as far as fungi are concerned - certain striking differences, aside from some similarities, have been noticed between the Agaricales
flora of the Upper, as well as the Lower Amazonas várzeas, as compared with the Central Amazonian
várzeas studied in the present paper. The supposed transition zones between várzea and igapó are worthy of further exploration.
