          Abstract

          As palmeiras oferecem um ecossistema especializado que abriga organismos variados, incluindo Myxomycetes. Este trabalho relata doze espécies de Myxomycetes encontradas em folhas mortas, espata e estipe de Acrocomia intumescens Drude (macaúba), Copernicea prunifera (Mill.) H. E. Moore (carnaúba), Mauritia flexuosa Mart, (buriti) e Orbygnia phalerata Mart, (babaçu). Constitui-se área de coleta o Município do Crato, Ceará, Nordeste do Brasil (7º 30'00" S, 39º 00' 00" W, 400-1200 m de altitude). Coletas aleatórias foram efetuadas e as frutificações foram pesquisadas em órgãos vivos ou mortos das palmeiras. Exsicatas foram depositadas no Herbário UFP (Departamento de Botânica da Universidade Federal de Pernambuco, Recife - PE, Brasil). As espécies registradas pertencem aos gêneros Ceratiomyxa (1), Dictydium (1), Arcyria (1), Hemitrichia (1), Badhamia (1), Fuligo (1), Physarum (3), Stemonitis (2) e Comatricha (1). Ceratiomyxa fruticulosa (Miill.) Macbr., Physarum stellatum (Mass.) Mart., Stemonitis pallida Win. e Comatricha typhoides (Bull.) Rost. são referidas pela primeira vez para este tipo de substrato. Este trabalho eleva para 35 o número de espécies de Myxomycetes assinaladas sobre palmeiras até o momento.

          Translated abstract

          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.
