Fungos poliporóides de manguezais da apa de Algodoal/Maiandeua, município de Maracanã, Estado do Pará

Abstract

Polyporoid fungi is an expression used to designate all species that present the poroid hymenial surface. They are mostly macroscopic, with cellulolytic and/or lignolytic activity, contribute to wood decomposition and participate in the recycling process of the mangrove ecosystem. The Environmental Protection Area (EPA) of Algodoal/Maiandeua is located in the coastal plain of NE Pará, with mangroves as one of the colonizing ecosystems of the APA. The aim of this work is to survey the polypore fungi of mangroves of the Algodoal APA. The material studied was collected during 03 field trips from July 1998 to February 1999. The usual techniques for collecting macroscopic fungi were followed. The collected material was deposited in the MPEG herbarium. For the identification stage, macro and microscopic observations were made, with the help of specialized literature, and comparative studies with specimens deposited in herbaria. Ninety-nine specimens of polyporeid fungi from the class Basiodiomycetes were collected. To date, 69 specimens have been studied and identified in 13 taxa: Antrodia sinuosa (Fr.) Karst., Gloeophyllum striatum (Sw.: Fr.) MUIT.,Hexagonia hydnoides (Fr.) M. Fidalgo, Hexagonia papyracea Berk., Inonotus sp., Lentinus crinitus (L.: Fr.) Fr, Phellinus coelhoi M. A. Sousa, Phellinus gilvus (Schw.) Pat., Phellinus senex (Ness & Mont.) Imazeki, Phellinus sp., Pycnoporus sanguineus (L.: Fr.) MUIT., Trichaptum abietinum (Dicks.: Fr.) Ryv. and Tyromyces sp. The identified taxa represent the families Hymenochaetaceae and Polyporaceae. The Polyporaceae family is better represented in terms of number of species and specimens collected. Tyromyces sp. was found in all collections and was resistant to tidal influence. Trichaptum abietinum is the first reference for Brazil.
