Fomitopsis schrenkii is a newly isolated species from the genus Fomitopsis. Previously thought to be identical to the red-belted conk, DNA analysis shows it is in fact a distinct species.[1] This species is named after Herman von Schrenk, a respected name in forest pathology.[1] It occurs most frequently in the Southwestern United States, and has a somewhat limited range.[1] It prefers coniferous trees and rarely associates on hardwoods.[1] This substrate preference and location range is most helpful in distinguishing F. schrenkii from its close relative, F. mounceae.
Description
Fomitopsis schrenkii is a perennial, woody conk with a fan-like shape.[1] The surface is smooth and can be resinous, and usually ends with a bumpy margin.[1] The colour usually follows a set pattern- at base a whiteish orange, then darkening to a true orange or brown, then lightening to a creamy-white at the margins.[1] Older specimens will darken to a grey or brown colour, with bands less visible but still distinct.[1] If broken open, the woody context of the conk is a light yellow or tan colour, with no distinct bands.[1] The underside of the conk is a light yellow or white colour, with 3-4 round pores per millimetre.[1] This species stains reddish or light brown in KOH.[1]
