Erioscyphella insulae

Ciri dan struktur

Characterized by pure white apothecia unlike related species Lachnum nothofagi, and two-layered ectal excipulum. Apothecia gregarious, superficial, 0.7–1.4(–2.5) mm in diameter, short- and thick-stipitate, up to 0.8 mm high, externally white to cream throughout but sometimes pale brown in the lower parts, covered with white hairs. Disc concave, cream to pale yellow (fresh state not observed). Ectal excipulum composed of two layers: outer layer textura angularis, up to 20 µm thick, 3–28 × 2–8 µm, hyaline, thin to relatively thick-walled, with cell walls smooth; inner layer up to 15 µm thick, textura porrecta composed of hyaline hyphae up to 5 µm wide. Medullary excipulum up to 100 µm thick, composed of hyaline hyphae forming textura intricata; hyphae up to 3 µm wide. Hairs straight or irregularly curved, cylindrical, sometimes branched, up to 125 × 2.5–3.0 µm, hyaline, completely granulate, thin-walled; lacking crystals or resinous materials; apex usually equipped with hyaline apical amorphous materials. Asci (88–)92–101(–106) × 6–7.3(–8) µm (av. 96 ± 4.5 × 6.7 ± 0.6 µm, n = 18), 8-spored, thick-walled, cylindrical-clavate, arising from ascogenous hyphae branching several times; pore blue in MLZ without 3% KOH pretreatment; croziers absent at the basal septa. Ascospores (24–)26.7–34.5(–39) × (1.8–)1.9–2.3(–2.5) µm (av. 31 ± 3.9 × 2.1 ± 0.2 µm, n = 18), Q = (11–)12.5–17(–20) (av. 14.7 ± 2.3, n = 18), showing various shapes and lengths, usually long fusiform and sometimes hypsiloid or sigmoid due to bending of both ends, sometimes swelling or constricted irregularly, aseptate or one- to three-septate (usually one-septate).

Habitat dan peran ekologis

Colony of NBRC 114445/ TNS -F-26500 and NBRC 114459/ TNS -F-39720 on PDA relatively thick-planar, pruinose, white to cream, ivory at the margin, pale sepia. Sectors and zonation absent. Aerial mycelium white to pale ocher, mainly developed except in the margin, not forming mycelial strands. Soluble pigment amber colored produced at the center. Margin unclear, flat and immersed into agar, radially undulate. Anamorph not seen.
