Notes:
Found by Neil Mezache. Growing on an insect larvae, likely lepidopteran but I’m not certain in the identity of the host. The host was embedded in a very well rotted, partially buried hardwood stick. Asci with apical caps. Spores disintegrating into part-spores. Entire spores up to 143.3 µm long. Part-spore measurements from Piximetre: (4.6) 4.8 – 6.3 (8.1) × (1.5) 1.6 – 2.1 (2.2) µm, Q = (2.3) 2.4 – 3.7 (5.1); N = 30, Me = 5.5 × 1.9 µm; Qe = 2.9
Individual part-spores: 4.79 × 2.00 µm, 5.08 × 2.12 µm, 5.31 × 1.93 µm, 4.76 × 1.64 µm, 5.52 × 1.77 µm, 8.12 × 1.60 µm, 5.91 × 1.87 µm, 5.10 × 2.01 µm, 5.29 × 1.96 µm, 5.72 × 1.88 µm, 5.29 × 1.47 µm, 5.58 × 1.82 µm, 4.80 × 1.83 µm, 7.05 × 1.88 µm, 5.02 × 2.10 µm, 6.22 × 1.96 µm, 4.98 × 2.06 µm, 5.45 × 1.68 µm, 5.14 × 1.95 µm, 5.57 × 2.01 µm, 6.30 × 1.60 µm, 5.33 × 1.94 µm, 5.27 × 1.90 µm, 6.52 × 1.76 µm, 5.03 × 2.15 µm, 5.66 × 2.02 µm, 4.74 × 1.91 µm, 5.32 × 2.01 µm, 5.34 × 2.05 µm, 4.59 × 1.98 µm
