Oruus

Oruus is a genus of fungi in the family Boletaceae. The genus was described by mycologist Andreas Albert Penzig in 1901. Oruus fungi are typically found in tropical and subtropical regions. They are characterized by their fleshy fruiting bodies, which often have a cap and stem. The pores on the underside of the cap are typically small and round.

Species within the Oruus genus are saprotrophic, meaning they obtain nutrients from dead organic matter. They play a role in the decomposition of wood and leaf litter in their respective ecosystems. While some species of Boletaceae are edible, the edibility of Oruus species has not been extensively studied, and it is generally advisable to avoid consuming unknown fungi.

The taxonomy of Oruus has seen some revisions over time, with some species previously assigned to Oruus later being reclassified into other genera or vice versa. Research into the phylogenetic relationships of Oruus continues to refine our understanding of this genus and its place within the broader Boletaceae family.
