Pileipellis composed of filamentous, hyaline, smooth, thin-walled hyphae, 3-5 µm wide, densely interwoven; uppermost layer strongly separated by gelification, with occasional branching, and emergent terminal elements with rounded apices, septate and with coarse, prominent clamp connections at the septa.
