Pileipellis an intricate trichoderm to a slightly gelatinised intricate trichoderm, made of densely interwoven, thin-walled, smooth, 100–130 µm thick, hyaline hyphae 3–10 µm wide. Terminal cells of hyphae 19–30 × 4–11 µm, cylindrical to subcylindrical, subventricose to subfusiform, rarely inflated to clavate. They turn slightly yellow when wetted and become transparent to pale yellow when treated with KOH. Stipitipellis 30–60 µm thick, with a thin layer of gluten, hymeniform, composed of thin-walled, erect hyphae, with brown extracellular pigment; terminal cells of hyphae 17–40 × 4–8 µm, cystidioid, broadly clavate or ventricose. All hyphae show no chromogenic reaction in Melzer’s. Clamp connections absent in all tissues.</p></div>	https://treatment.plazi.org/id/E0126A5F1B9A554DA727C056FC84FB11	Public Domain	No known copyright restrictions apply.
