Resumen

PONTE, Márcia Percília Moura Parente; CAVALCANTI, Laise de Holanda  y  MOBIN, Mitra. Myxomycetes of the Parque Zoobotânico - Teresina, Piauí, Brazil. Acta Bot. Bras. [online]. 2003, vol.17, n.1, pp.1-18. ISSN 0102-3306.  http://dx.doi.org/10.1590/S0102-33062003000100001.

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.
