Abstract
Visando ampliar o conhecimento sobre a mixobiota do Piauí, foram realizadas coletas no Parque Zoobotânico de Teresina (05º 05' 12'' S, 42º 48' 48'' WG). A vegetação do Parque caracteriza-se como um cerradão com representantes da mata de cocais, que oferecem substratos potencialmente favoráveis ao desenvolvimento de Myxomycetes. Esporocarpos foram coletados no período chuvoso e início da estiagem (março a junho de 1999), identificados e depositados no herbário UFP (Universidade Federal de Pernambuco). Foram obtidas 101 amostras, correspondentes a 19 espécies, distribuídas nas famílias Ceratiomyxaceae (Ceratiomyxa fruticulosa (Mull.) Macbr., Clastodermataceae (Clastoderma debaryanum Blytt), Cribrariaceae (Cribraria microcarpa (Schrad.) Pers., C. violacea Rex, Dictydium canceilatum* (Batsch.) Macbr.), Enteridiaceae (Lycogala exiguum* Morgan.), Physaraceae (Craterium aureum* (Schum.) Rost., Physarum bogoriense* Racib., P. melleum (Berk. & Br.) Massee, P. nucleatum Rex, P. pusilium* (Berk. & Curt.) G. Lister), Trichiaceae (Arcyria denudata (L.) Wett., A. cinerea (Bull.) Pers., Hemitrichia calyculata (Speg.) Farr, H. serpula (Scop.) Rost., Metatrichia vesparium (Batsch) Nann.-Brem., Perichaena depressa Lib.) e Stemonitaceae (Comatricha typhoides (Bull.) Rost., Stemonitis smithii Macbr.). Exceto H. calyculata e H. serpula, todos os táxons são referidos pela primeira vez para o município de Teresina; as espécies assinaladas com um asterisco constituem novos registros para o Piauí.
Aiming to increase the knowledge about the myxobiota of Piauí State, Brazil, collections were done in the undertaken Zoobotanical Park of Teresina (05° 05' 12'' S, 42° 48' 48'' WG). The vegetation of the Park is a savanna ("cerradão") with "cocais" forest representative, offering substrates potentially favorable to the development of Myxomycetes. Sporocarps were collected in the rainy season (March to June 1999), identified and deposited at the UFP herbarium (Federal University of Pernambuco). One hundred and one samples were collected, corresponding to 19 species, distributed in the families: Ceratiomyxaceae (Ceratiomyxa fruticulosa (Mull.) Macbr., Clastodermataceae (Clastoderma debaryanum Blytt), Cribrariaceae (Cribraria microcarpa (Schrad.) Pers., C. violacea Rex, Dictydium cancellatum* (Batsch.) Macbr.), Emeridiaceae (Lycogala exiguum* Morgan), Physaraceae (Craterium aureum* (Schum.) Rost., Physarum bogoriense* Racib., P. melleum (Berk. & Br.) Massee, P. nucleatum Rex, P. pusilium* (Berk. & Curt.) G. Lister), Trichiaceae (Arcyria denudata (L.) Wett., A. cinerea (Bull.) Pers., Hemitrichia calyculata (Speg.) Farr, H. serpula (Scop.) Rost., Metatrichia vesparium (Batsch) Nann.-Brem., Perichaena depressa Lib.) and Stemonitaceae (Comatricha typhoides (Bull.) Rost., Stemonitis smithii Macbr.). With the exception of H. calyculata and H. serpula, all taxa are referred for the first time for the Municipality of Teresina, and the species with an asterisk constitute new record for the State of Piauí.
