Abstract

PINHEIRO VELLOSO, Jorge Renato et al. First records of aseroe rubra labill. and phallus indusiatus vent. for the Pampa biome, Brazil. Rev. Soc. cient. Parag. [online]. 2025, vol.30, n.2, pp.16-24. ISSN 0379-9123.  https://doi.org/10.32480/rscp.2025.30.2.1624.

The order Phallales encompasses species commonly known as "stinkhorns" and "veils of the bride". Although recognized for their peculiar morphological traits, their representation in the mycobiota of Rio Grande do Sul state (Southern Brazil) is scarce, especially in the Pampa biome, which is one of the least studied in the country. The Pampa, located only in this Brazilian state, features predominantly grassland vegetation but faces challenges due to the expansion of monocultures and low representation in protected areas. The study focused on the collection of specimens, including Phallus indusiatus and Aseroe rubra, representing the first records for the biome. It utilized collection and identification methodologies, comparing morphological characteristics with specialized literature. The research resulted in the identification of these two species and the development of an identification key for the species of Phallales in the Pampa, as well as a checklist and a distribution map. The work highlights the biodiversity present in the region, as well as contributing to the conservation and appreciation of the Pampa biome, a natural and cultural heritage. The new recorded occurrences represent a significant advancement in the recognition of the region's fungal richness. Overall, the study compiles data on seven species (five with previously known occurrences for the biome, and two cited for the first time) from five genera of Phallales, reflecting the urgent need for research due to threats to the local ecosystem.
