(Ascomycota: Hypocreales, Hypocreaceae) is the only known parasite of the mutualistic fungi cultivated by fungus-growing ants (Formicidae: Myrmicinae: Attini: Attina, the "attines"). Despite its ecological role, the taxonomy and systematics of have been poorly addressed. Here, based on morphological and phylogenetic analyses with three molecular markers (internal transcribed spacer, large subunit ribosomal RNA and the translation elongation factor 1-alpha), we describe and as new species isolated from fungus gardens of ant species.

Article Synopsis
- The study explores the presence and phylogenetic diversity of Escovopsioides fungi in the fungus gardens of various ant species, focusing on 21 isolates from Brazil.
- Results showed low genetic diversity among most isolates, identifying them as Escovopsioides nivea, while one isolate was a new species.
- The research indicates that Escovopsioides fungi can inhibit the growth of the mutualistic fungus cultivated by leafcutter ants, suggesting a potential antagonistic role in the ant-fungus symbiosis.

The post-pharyngeal gland (PPG) occurs in ants and some Sphecidae wasps. Among its several roles is the storage of lipids from food. In order to investigate the effect of lipids on the cell, especially on mitochondria and peroxisomes, the present study was aimed at examining the peroxisomal and mitochondrial population in the PPG of Atta sexdens rubropilosa after lipid supplementation by confocal laser scanning microscopy and transmission electron microscopy.
