Basidiodendron

Basidiodendron is a genus of fungi belonging to the family Sebacinaceae. These fungi are characterized by their small, resupinate (crust-like) fruiting bodies that are typically found on decaying wood or bark.

Description: Basidiodendron fungi are generally inconspicuous, forming thin, effused layers on their substrate. The color of the fruiting body can range from whitish to cream-colored or pale brown. Microscopically, they are defined by their basidia, which are generally globose to subglobose, and their lack of cystidia. The spores are typically globose to broadly ellipsoid, smooth, and hyaline (translucent).

Habitat and Distribution: Species of Basidiodendron are found worldwide, primarily in temperate and tropical regions. They are saprophytic, meaning they obtain nutrients from dead organic matter, playing a role in decomposition in forest ecosystems. They are commonly found on the underside of decaying branches and logs.

Taxonomy: The genus Basidiodendron was established to accommodate certain species previously placed in other genera, reflecting a better understanding of their phylogenetic relationships based on molecular data. The exact number of species within the genus can fluctuate as taxonomic revisions occur.

Ecology: As saprophytes, Basidiodendron species are important decomposers, contributing to the breakdown of woody debris and nutrient cycling within forest ecosystems. Their inconspicuous nature means they are often overlooked, but they play a vital role in fungal communities.

Identification: Accurate identification of Basidiodendron species typically requires microscopic examination of the fruiting body to observe the basidia and spores. Macroscopic features alone are often insufficient for reliable identification.
