Exidia recisa

Ciri dan struktur

Basidiomata annual, cupulate-orbicular, up to 3 cm in diam., rarely up to 5 cm in diam., narrowly attached, later partly fusing together but remaining separable, up to 1 cm thick, gelatinous. Hymenial surface even or variably folded, rarely bearing scattered granular projections up to 0.1 mm long, at first ochraceous- to reddish-brown, later dark brown, in dry condition darkening to nearly black. Abhymenial surface rough, covered by tightly arranged dots, reddish-brown or dark brown. Margin free, concolourous with hymenial surface, entire, even or indistinctly lobate, in older basidiomata sometimes indistinctly incised. Hyphal structure monomitic, hyphae clamped; context hyphae hyaline or yellowish-brownish, occasionally encrusted, thin- to slightly thick-walled, interwoven or subparallel, anastomosing, 1–6.5 μm in diam., subhymenial hyphae hyaline or yellowish-brownish, occasionally encrusted, thin- to slightly thick-walled, predominantly interwoven, 1–4 μm in diam., basidia-bearing hyphae with a distinct wall, 1.5–4 μm in diam. Hyphidia with a hyaline or brownish, often encrusted, hyphoid or nodulose stem, 2–12 μm in diam., and hyaline apical branches, 0.5–1.2 μm in diam., covered by yellowish-brown gelatinous matrix and forming a continuous layer up to 80 μm thick. Probasidia distinctly tapering or more rarely clavate, 10.5–25 × 5–9 μm. Basidia four-celled, ellipsoid-ovoid, often somewhat tapering to the base, sometimes obliquely septate, (12–) 12.5–18 (–19) × (6.2–) 6.3–10.8 (–11.5) μm (n = 60/6), sterigmata up to 35 × 1.5–2.5 μm. Basidiospores narrowly cylindrical to allantoid, distinctly curved, (9.2–) 11.0–17.9 (–19.2) × (2.8–) 2.9–4.2 (–4.3) μm (n = 240/8), L = 13.14–15.82, W = 3.15–3.83, Q = 3.15–4.48.

Habitat dan peran ekologis

Exidia recisa is a wood-rotting species, typically found on dead attached twigs and branches. It was originally recorded on willow and most frequently occurs on this substrate, although it has also been reported on alder, and Prunus species. Exidia recisa typically fruits in autumn and winter. It is widely distributed in Europe, but its distribution elsewhere is uncertain because it has only recently been distinguished from morphologically similar species in North America and Asia. Based on DNA sequencing, it is said to be present in North America as well as the more common E. crenata.

Catatan identitas dan cakupan

• Nama diterima mengikuti Catalogue of Life Base2026-09-11; uraian mempertahankan konsep dan nama sumber aslinya.
• Uraian digabungkan dari sumber spesies yang sama; lingkup geografis, bahan, dan kultur setiap sumber dipertahankan. Preserve original treatment localities, hosts and substrate scope. Materials examined describe documented specimens, not the full global range. Original geographic, specimen and life-cycle scope retained; source import awaits individual editorial review.
• Impor dan terjemahan otomatis belum diperiksa editorial per profil. Struktur reproduktif yang disebutkan tidak membuktikan seluruh siklus hidup diketahui.
• Pengukuran pada uraian mengikuti spesimen, kultur, dan metode sumber; angka tidak diperluas ke semua populasi.
