Observation 320067: “Discomycetes” Sacc.

Notes:
Growing on a hardwood stick with Ionomidotis fulvotingens (observation 320068). Apothecia superficial on a black subiculum. Releasing a purple pigment in Melzer’s reagent when pretreated with 1M KOH and not without. All structures inamyloid. Entire apothecia appearing blue-green in 1M KOH. Ectal excipulum of textura angularis and composed of irregularly-shaped brownish cells. Paraphyses filiform and branched. Paraphyses coated with a purple substance in distilled water and apically with a brownish substance. Asci 8-spored, inoperculate, unitunicate and clavate. Asci with croziers. Asci measurements: (26.7) 26.74 – 36.37 (36.4) × 4.1 – 5.29 (5.3) µm, Q = 5.1 – 7.47 (7.5); N = 4, Me = 30.4 × 4.7 µm; Qe = 6.5. Spores smooth, hyaline, non-septate and biguttulate. Spore measurements: (4.2) 4.5 – 5.3 (5.8) × (1.6) 1.7 – 2.1 (2.3) µm, Q = (2.1) 2.2 – 3.1 (3.2); N = 20, Me = 4.9 × 1.9 µm; Qe = 2.6
