The study of seed-borne fungi in forest seeds may bring important information because some of these microorganisms can cause damage to seeds as well as to the production of seedlings. This research aimed to evaluate germination and survey the seed-borne fungi of three lots of angico-vermelho (Parapiptadenia) from São João do Oeste, Santa Catarina state (SJO), Sobradinho (SO) and Santa Cruz do Sul, Rio Grande do Sul state (SCS), in addition to detecting their transmission and pathogenicity. The presence of the fungal genus Phomopsis sp as potentially pathogenic and the saprophytic fungi Penicillium sp. and Aspergillus sp. was detected through seed health testing. Among the lots tested (SJO and SCS), transmission and pathogenicity of Phomopsis sp was verified in the SCS lot, causing dark necrotic lesions on the folioles edges, wrinkling of ungerminated seeds, and percentage reduction of seedling emergence in seed-plots.
