The shrub has slender, spinescent, pruinose branchlets. Stipe surface pruinose to floccose in the apex. Apothecia are usually concave and often pruinose. It has terete red to brown branchlets that are glabrous and pruinose. The cap surface is smooth, faintly translucent-striate when moist, at first pruinose but soon naked. The cap surface has a whitish sheen because of its pruinose coating. The lightly pruinose branchlets are often a dark red-brown in colour. Like the cap, it is at first pruinose, but smooths out in age. It lacks an annulus (ring), is hollow and pruinose near the top. The stipe are entirely pruinose and has a bulbose base as general. The stipe is pruinose (powdery) or smooth towards the upper region. The stipe are no pruinose, only in the apex or the upper half. The stipe of "M. aetites" has a pruinose apex and isglabrous below. Above the base, the stem is smooth, and pruinose toward the apex. Adult males have a pruinose coating on the synthorax and some of the abdomen.
