Hapoillisia

Hapoillisia is a genus of fungi in the family Hymenochaetaceae. The genus was circumscribed by mycologist William Murrill in 1910. Hapoillisia species are characterized by their resupinate (attached to the substrate by the underside) basidiomata, which are typically pale to dark brown in color. The genus is known for its distinctive, often irregularly shaped pores on the underside of the basidiomata. Hapoillisia species are saprobic, meaning they obtain nutrients by decomposing organic matter. They are commonly found in temperate and boreal forests, often growing on decaying wood or other organic substrates. The genus includes several species, with Hapoillisia abietina being one of the most well-known. Hapoillisia fungi are not typically edible and are generally considered inedible due to their small size and potential toxicity. The genus is of interest to mycologists for its unique morphological features and ecological roles in forest ecosystems. Further research is needed to fully understand the taxonomy, ecology, and potential applications of Hapoillisia species.
