The confluence zone with the context consists of the same, but less compact hyphae. +Subpellis +faintly differentiated, with similar but less compact hyphae than the deep suprapellis. +Context of pileus +thin, but not measurable, mainly composed of oval physaloidal elements 60‒100 × 10‒30 µm, mixed with narrow hyphae. +Volva +400–1000 µm thick, distinctly 3-layered: outer layer about 75 µm thick, composed of parallel hyphae strongly twisted and entangled with transversally oriented hyphae 5–6(8) µm wide; intermediate layer composed of similar but less twisted, more or less intricate hyphae forming a firm structure; inner layer 150–200 µm thick, composed of sphaerocysts (28)30–70(90) × 25–60(63) µm, less frequently ovoid or broadly clavate physaloidal hyphae (57)60–130 × 20–30 µm (acrophysalids) and filamentous hyphae 4–9 µm wide. In collection BRNM 695616 the lower part of the universal veil has a thick (600 µm) inner stratum and thinner intermediate stratum.
