Index Fungorum Number: 460762                         Faceoffunfi Number:N/A

Saprobic, sexual morph: Ascomata 350-425 µm diam., 510-630 µm high, superficial, globose, ostiolate, short papillate, black, mostly clustered. Papilla 230-280 µm diameter. Peridium 45-95 µm wide, comprising two strata, an inner stratum of hyaline thin-walled globose cells, and an outer layer of brown thick-walled angular cells. Pseudoparaphyses 2-3 µm wide, filiform, numerous, septate, anastomosing above the asci, embedded in a gelatinous matrix. Asci 135-180¬17 x 5-25 µm, 8-spored, cylindric-clavate, pedicellate, bitunicate, fissitunicate, with an ocular chamber. Ascospores 31-42 x 7.5 x 12.5 µm, 2-seriate, fusiform, initially 1-septate, becoming 3-septate when mature, strongly constricted at the central septum, basal parts slightly longer and narrower than apical part, hyaline, becoming pale brown when mature, and dark brown following release from the ascomata, with apical cellular appendages. Asexual morph: Undetermined.

NOTES: Herpotrichia nypicola appears to be known only from the original collection on Nypa fruticans collected at Kuala Selangor mangrove, Malaysia (Schmit & Shearer 2003). There are no cultures and it needs to be recollected, isolated and sequenced to confirm its placement in Herpotrichia. The genus comprises circa 101 species all terrestrial with the exception of H. nypicola (Wijayawardene et al. (2017). In Jones et al. (2015) this species was paced in the Lophiostomataceae. However, Wijayawardene et al. (2017) show it groups in the Melanommataceae, although the type species has not been sequenced (Wijayawardene et al. 2012).
