De março/1988 a março/1989, mensalmente, foram coletadas o total de 450 amostras de solo de rizosferas de plantas de dunas do Parque Estadual da Ilha do Cardoso, Estado de Sáo Paulo, com a finalidade de se verificar a ocorrência de fungos micorrízicos vesículo-arbusculares (MVA). As plantas mais constantemente investigadas foram: Baccharis trimera DC. (Compositae), Blutaparon portulacoides (St. Hü.) Mears (Amaranthaceae), Dalbergia hecastaphylla (L.) Taub. (Legurninosae), Hydrocotyle bonariensis Lam. (Umbelliferae),Ipomoeapes-caprae (L.)Sweet(Convolvulaceae), Polygaid cyparisseas St. Hül & Moq. (Polygalaceae), além de gramíneas, ciperáceas e outras, que foram coletadas mais esporadicamente. O solo foi tratado pela técnica de decantação e peneiramento em via úmida. Foram verificados 14 taxons de fungos MVA: Acaulospora scrobiculata Trappe, Acaulospora tuberculata Janos & Trappe, Cigaspora gigantea (Nicol. & Gerd.) Gerd. & Trappe, Glomus fasciculatum (Thaxter) Gerd. & Trappe emend. Walker & Koske, Glomus globiferum Koske & Walker, Glomus monosporum Gerd. & Trappe, Sclerocystis sinuosa Gerd. & Bakshi, Scutellospora calospora (Nicol & Gerd) Walker & Sanders, Scutellospora coralloidea (Trappe, Gerd. & Ho) (Walker & Sanders), Scutellospora gilmorei (Trappe & Gerd.) Walker & Sanders, Scutellospora gregaria (Schenck & Nicol.) Walker & Sanders, Scutellospora pérsica (Koske & Walker) Walker & Sanders, Scutellospora verrucosa Koske & Walker) Walker & Sanders e Scutellospora sp. São apresentadas descrições taxonómicas, comentarios e murônimos dos taxons verificados.

The investigated plants were: Baccharis trímera DC. (Compositae), Blutaparon portulacoides (St. Hil.) Mears (Amaranthaceae), Dalbergia hecastaphylla (L.) Taub. (Legumiosae), Hydrocotyle bonariensis Lam. (Umbelliferae), Ipomoea pes-caprae (L.) Sweet (Convolvulaceae), Polygala cyparisseas St. Hill & Moq. (Polygalaceae); Gramineae, Cyperaceae and other plants were occasionaly collected. The soil was prepared according the wet sieving and decanting technique. It was observed the following 14 taxa of VA M fungüs: Acaulospora scrobiculata Trappe, Acaulospora tuberculata Janos & Trappe, Gigaspora gigantea (Nicol. & Gerd) Gerd & Trappe, Glomus fasciculatum (Thaxter) Gerd. & Trappe emend. Walker & Koske, Glomus globiferum Koske & Walker, Glomus monosporum Gerd. & Trappe, Sclerocystís sinuosa Gerd. & Bakshi, Scutellospora calospora (Nicol. & Gerd.) Walker & Sanders, Scutellospora collaroidea (Trappe, Gerd. & Ho) Walker & Sanders, Scutellospora gilmorei (Trappe & Gerd.) Walker & Sanders, Scutellospora gregaria (Schénck & Nicol.) Walker & Sanders, Scutellospora pérsica (Koske & Walker) Walker & Sanders, Scutellospora verrucosa (Koske & Walker) Walker & Sanders and Scutellospora sp. Are presented taxonomical, coments and muronyms of the studied taxa.
