Abstract

ALVES, Maria Helena  and  CAVALCANTI, Laise de Holanda. Myxomycetes on palm trees (Arecaceae). Acta Bot. Bras. [online]. 1996, vol.10, n.1, pp.1-7. ISSN 0102-3306.  https://doi.org/10.1590/S0102-33061996000100001.

Palm trees are specialized ecossystems which hosts a wide variety of organisms, including Myxomycetes. This paper reports twelve species of Myxomycetes found on dead leaves, spathes and stipitis of Acrocomia intumescens Drude, Copernicea prunifera (Mill.) H. E. Moore, Mauritia flexuosa Mart., and Orbygnia phalerata Mart. The collecting area is located in the Municipality Crato of Ceará State, Northeastern Brazil (7º 30'00" S, 39º 00' 00" W, 400-1200 m altitude). Samples were taken at random and Myxomycetes fructifications were searched on dead and living organs of palm trees. Exsiccatae have been deposited in the Herbarium UFP (Department of Botany, Federal University of Pernambuco, Recife-PE, Brazil). The species registered belong to the genera Ceratiomyxa (1), Dictydium (1), Arcyria (1), Hemitrichia (1), Badhamia (1), Fuligo (1), Physarum (3), Stemonitis (2) and Comatricha (1). Ceratiomyxa fruticulosa (Miill.) Macbr., Stemonitis pallida Win, Comatricha typhoides (Bull.) Rost. and Physarum stellatum (Mass.) Mart, are reported for the first time on this substrate. This study raises to 35 the number of Myxomycetes species occurring on palm trees substrates.
