Clathrus treubii (C. Bernard) Lloyd (Phallaceae) is a rare stinkhorn fungus which can be recognised by its red to pink receptacle, not fused at its base. This macrofungus was originally described from fresh material found in Bogor Botanical Garden (Indonesia) in 1906, and later, in 1980, from material preserved in spirits. To date, no subsequent occurrence of C. treubii from the type locality has been reported. This study is aimed at updating the current knowledge of C. treubii, providing a morphological description, and contributing to the molecular data of this species. During field surveys in the forest at the IPB University campus (Bogor, Indonesia) in 2022–2023, the basidiome of a red Clathrus was spotted. The fresh basidiome was studied and the combination of morphological and molecular analysis confirmed the identity of the specimen as C. treubii. The morphology of the basidiome is described based on macroscopic and microscopic features, and illustrations are provided. The molecular and phylogenetic analysis was made using ITS rDNA sequence data. The collected specimen is designated as an epitype due to the impossibility of sequencing the DNA of the holotype. This study provides the first molecular data on C. treubii and can be used for future studies of Phallales.
