(Figs. 2–6)</p><p>MycoBank: MB: 859598</p><p>Diagnosis: — Bolbitius corrugatus differs from B. excoriatus by having a yellow, not brown, pileus; from B. titubans sensu lato, its smaller, more angular and hexagonal basidiospores; from B. coprophilus by its yellow turning to pale buff pileus and slightly smaller, more angular and hexagonal basidiospores; and from B. elegans by being non-gasteroid, having stouter basidiocarps and having hexagonal basidiospores.</p><p>Holotype:— SCOTLAND.

GenBank: PV021289 (ITS); PV021294 (LSU).</p><p>Etymology: —The specific epithet ‘ corrugatus ’ refers to the species’ corrugated pileus.</p><p>Time-lapse: —Available at https://youtu.be/AvJDKkuPvG8</p><p>Description:—Pileus 4–25 mm wide and 1–4.5 mm high when mature; campanulate when young, expanding to plano–convex, broadly umbonate; surface wrinkled and covered in a gelatinous layer when immature, developing to corrugated from the margin to start of the broad umbo, disk with protruding vein-like reticulum at maturity; margin crenate; predominantly lemon yellow, drying to pale–cream from the margin inwards, finally pale olive at the edge with the centre dark yellow; surface viscid with a glutinous top layer particularly in humidity, excoriate with drying. Lamellae free or narrowly adnexed, subdistant, thin, with one series of lamellulae extending to approximately 20% to 50% of the gill; whitish when young, maturing to orange, then light brown; edge white, crisped to finely serrate. Stipe 8.5–71 × 0.5–1.7 mm, equal, flocculose, with a bulbous base up to 3 mm wide, sometimes shortly tapering but not rooting; pale white, with a yellow–green tint which concentrates at the base, drying to pale buff. Odour and Taste not distinctive.</p><p>Basidiospores [151, 4] (7.8)9.0–10.5(12.0) × (5)6–7(8) µm, mean: 9.9 × 6.4 µm, width in front view: 5–6.5(6.6) um, Q = (1.25)1.37 × 1.75(1.83), Qav = 1.67; variable in shape, angular or subhexagonal, lentiform-oblong, often slightly irregular in side view, irregular in front-view, yellow-brown in KOH, thick-walled, with central or slightly eccentric germ pore 2.2–3.5 µm wide. Basidia 2-, 3- and 4-spored, 19–25 × 9–12 µm, clavate. Pseudoparaphyses present, clavate. Cheilocystidia 20–39 × 9–21 µm, variable in shape: broadly fusiform, utriform, lageniform with a long or short neck, clavate, rarely sphaeropedunculate, hyaline, thin-walled, intermixed with basidia. Pleurocystidia absent. Pileipellis hymeniform, consisting of pyriform, subglobose, broadly clavate to sphaeropedunculate elements (15–35 × 11–23 µm), covered in a gelatinous layer (but this may not show on dried basidiocarps). Stipitipellis a cutis, consisting of cylindrical hyaline hyphae, with caulocystidia singularly, in small groups, or in dense clusters of up to ten. Caulocystidia variable in shape: oblong-reniform, utriform, broadly lageniform or narrowly lageniform with slightly incurved walls (1–3 incurves), 20–39 × 10–19 µm.
