Conservation Status: Not of concern

Identification Notes:

Clavariadelphus sachalinensis is one of several small slender members of the genus that are characterized by fruiting from a dense mycelial mat that permeates and binds the substrate and by having narrowly ellipsoid or sway-backed spores Often these species can be found in large troops under conifers. All are initially pale yellow and become pinkish cinnamon to ochraceous cinnamon as they age. The entire upper portion of the club is covered with fertile tissue. Clavariadelphus lignicola is a third similar species, but has spores with average width greater than 6 µm (vs less than 5 µm) and seems to have a smaller geographic range, reportedly only Arizona, Colorado, and Utah. Clavariadelphus sachalinensis, described from Sakhalin Island, is widespread in western and northern North America.
