Taxonomy
Hortiboletus coccyginus was first described in California in 1975. Back then, it was known as Boletus coccyginus. In 2020, JL Frank transferred it to the genus Hortiboletus.[1]
Description
Hortiboletus coccyginus has a rosy-colored cap[1] that is about 2–6 cm (0.79–2.36 in) wide. Sometimes, the it cracks in older specimens. The stipe is about 1.5–7 cm (0.59–2.76 in) tall and about 0.5–2 cm (0.20–0.79 in) wide. The pores are yellow. While on younger mushrooms they do not bruise blue, older specimens occasionally stain bluish green.[4]
Habitat and ecology
Hortiboletus coccyginus grows under several different types of trees, including coast live oak, tanoak, and douglas-fir. It is known to grow in mixed forests, and it is known from California and Oregon.[3] Despite being rare, it is listed by the IUCN Red List as Least Concern.[1]
