Description:Basidiomata mature epigeous, pyriform to turbinate, 16–20 × 11–21 mm. Exoperidium incrusted with grains of sand, ornamentation of black spines (14F4) 0.6–1 mm long at the apical portion, and black verrucae (14F3) at the basal portion; the apical spines falling off with age. Endoperidium yellow- ish white (3A2) to yellowish grey (3A3), surface marked by areoles. Gleba powdery brown. Basal exoperidium composed of globose to subglobose sphaerocysts, 20–39 × 19–27 μm, disposed in non-regular chain at the base of the spines, which remains on endoperidium surface after the spines have fallen off, walls 1–2.2 μm thick, while the spines are formed by regular chains of sphaerocysts (like in L. perlatum), globose to pyriform, 21–28 × 14–18 μm, walls < 1.5 μm thick. Apical endoperidium composed of interwoven hyphae with inflated terminations, 8–17 μm diam, walls 1.3–2.2 μm thick, mixed with mycosclerids, irregular shape, 40–75 × 10–34 μm, walls 2–3.7 μm thick, weakly dextrinoid. Capillitium 3–5 μm diam, without pores and septa, walls 1–1.8 μm thick. Paracapillitium absent or rare. Basidiospores globose, 4–4.5 μm diam, punctate (A–B) often A in LM.
