Notes

The species is differentiated from other species by the size of the perithecia and the Neotropical distribution. Additionally, N. aurantiaca Luangsa-ard, Thanak. & Tasan looks morphologically similar to N. martiale , but differs in the type of ascospore. The first produce only whole (non-fragmenting) ascospores, while the latter produce ascospores either dissociated ( Luangsa-ard et al. 2017). In Colombia, this is the first record of the species for Tolima.

Diagnosis

Stromata erect, multiple to solitary, clavate to irregular, branched, orange to mustard yellow, 3.2 cm large, becoming purple in 3% KOH (Fig. 1 A). Perithecia immersed to loose, oblique in arrangement, ovoid to circular ostiole, 618-847 × 265-320 μm. Asci cylindrical, 2.8-4.6 μm in diam.; apical cap prominent, 1.6-2.1 × 2.5-2.9 µm. Ascospores filiform, hyaline, 270-315 × 1 µm. Growing on unidentified Coleoptera larvae.
