Xerocomus

Xerocomus is a genus of fungi in the family Boletaceae. The genus was circumscribed by mycologist Lucien Quélet in 1886. Xerocomus species are characterized by their small to medium-sized, often brown or grayish caps, and their white to cream-colored pores. They are typically found in deciduous forests, often growing on the ground or on dead wood. The genus is known for its saprobic lifestyle, meaning it obtains nutrients by decomposing organic matter.

Xerocomus species are generally considered inedible due to their small size and the presence of certain toxins. However, some species have been reported to be edible when cooked thoroughly. The genus is not well-studied, and many species remain undescribed. As of now, there are about 15 recognized species in the genus Xerocomus.

The taxonomy of Xerocomus is complex and has been subject to revision. Some species have been transferred to other genera, such as Boletus and Imleria. The genus is further divided into several sections based on morphological characteristics.

Xerocomus fungi are of interest to mycologists due to their unique characteristics and the potential for new species discoveries. However, their small size and often cryptic nature make them challenging to study. Despite these challenges, the genus Xerocomus continues to be a subject of interest in the field of mycology.
