The classified Kou forest is one of the densest plant formations in Burkina Faso. It covers
an area of 117 hectares and is inhabited by a diversity of species. Indeed, inventories conducted
in the forest indicate a floristic wealth of around 277 species (Guinko, 2005) and a diversity of
fauna (Ouédraogo et al., 2011). Mycological studies have also been done on this forest, but
limited to ectomycorrhizae of the genera Russula (Sanon et al., 2014), Amanita (Dabiré, 2020),
Boletus (Bakiono, 2024) and phytopathogenic polypores (Nankoné, 2022; Kusiele-Somda,
2024). As yet, few studies have looked at saprophytic macromycetes, particularly the Agaricus
genus. Fungi of this genus are important for maintaining environmental balance, contributing
to the natural decomposition of organic matter and the recycling of nutrients to benefit plants
(Roux, 2006). However, they risk to disappear unknown because, in despite of its status as a
forest under protected status, the Kou classified forest suffers from the adverse effects of
unfavorable climates and anthropic activities, which constitute threats to the survival of the
species (Yaovi et al., 2021). Many fungal species are threatened with extinction. An inventory
of the macromycetes of the Agaricus genus in this forest is needed to gain a better understanding
of them and to improve our knowledge of mycological diversity. This study thus aims to
highlight the presence of Agaricus fungi in the Kou classified forest, based on a taxonomic
analysis of two Agaricus species collected
