Erioscyphella otanii

Ciri dan struktur

Characterized by pure white minute apothecia (< 0.3 mm in diameter) unlike L. diminutum with rather colored apothecia, and smaller asci compared to similar species Lachnum minutum. Holotype. Japan, Hokkaido, Horonobe, Toikambetsu, Teshio Experimental Forest, Field Science Center for Northern Biosphere, Hokkaido University, 44.993978, 142.130125, ca 400 m, 11 Jul. 2018, on fallen leaves of Sasa senanensis, Y.Tochihara & K.Kaneko (TNS -F-81472). Apothecia scattered, superficial, minute, 0.1–0.3 mm in diameter, at first spherical and later urceolate, having well-developed stipes, up to 0.3 mm high, pure white, externally covered with short white hairs, never colored brown. Disc concave, almost enclosed by an incurving margin when fresh and dry, cream to pale yellow when dry (not observed when fresh). Ectal excipulum textura prismatica like stone pavings arranged in rows, 3–25 × 3–8 µm, hyaline, relatively thick-walled; cell walls smooth. Medullary excipulum textura intricata; hyphae up to 2.5 µm wide. Hairs straight, cylindrical or tapering toward the apices, up to 60 µm long, up to 5 µm wide near the bases and 2.5–3.0 µm wide near the apices, arising from swollen ectal excipular cells, hyaline, up to 3-septate (usually 1- or 2-septate), thin-walled, completely granulated; granules dense near the apices and coarse toward the bases; apex sometimes with a hyaline and inconspicuous apical amorphous materials not dissolved with CB / LA, lacking any crystals or resinous materials. Asci (33–)34–38.8(–41) × 4–5 µm (av. 37 ± 2.2 × 4.4 ± 0.4 µm, n = 15), 8-spored, cylindrical-clavate, relatively thick-walled; pore blue in MLZ without 3% KOH pretreatment; croziers absent at the basal septa.

Habitat dan peran ekologis

Colony of NBRC 114476/ TNS -F-81472 on PDA flat, partially protruding and forming mycelial mass, divided into two sectors. One sector flat, wooly to velvety, white to cream; dark ocher from the reverse. The other sector with wooly context, white and partly yellow; pale ocher from the reverse. Aerial mycelia developed throughout the colony, white, sparse to cottony, not forming mycelium strands. Margin distinct, flat and immersed into the agar. Soluble pigment absent. Asexual morph absent.
