Etymology – Name reflects its morphological similarity to the genus Lophiotrema.

Saprobic on decaying wood. Sexual morph: Ascomata scattered, immersed, coriaceous, globose to subglobose, brown to dark-brown, with central ostiole. Ostioles short papillate, produced pink pigment in the inner layer of the ostioles. Peridium thin to thick-walled, outer wall composed of several layers, brown to dark-brown, thin-walled cells of textura angularis, inner wall of loose cells of textura angularis. Hamathecium comprising numerous, anastomosing, hyaline, filiform, branched, septate, cellular pseudoparaphyses. Asci 8-spored, bitunicate, fissitunicate, cylindrical-clavate, pedicellate. Ascospores overlapping uni to bi-seriate, 2-celled, broadly fusiform with rounded ends, straight to slightly curved, 1(–3)-septate, hyaline, smooth-walled, with a primary septum nearly median, constricted at the septum, with obvious guttules, surrounded by a wide gelatinous sheath. Asexual morph: Undetermined.

Type species — Neolophiotrema xiaokongense G.C. Ren & K.D. Hyde

Note – Anteaglonium differs from Neolophiotrema in having hysterothecial ascomata, carbonaceous peridium and obovoid 2-celled ascospores with one or both ends obtuse or fusiform ascospores with acuminate apices (Mugambi & Huhndorf 2009, Hyde et al. 2013, Almeida et al. 2014, Jayasiri et al. 2016, Jaklitsch et al. 2018b, Jayasiri et al. 2019), while Neolophiotrema has coriaceous ascomata, and broadly fusiform ascospores with rounded ends. Neolophiotrema differs from Flammeascoma, which has trabeculate pseudoparaphyses (Liew et al. 2000) and carbonaceous ascomata, (Ariyawansa et al. 2015, Liu et al. 2015), whereas Neolophiotrema has coriaceous ascomata, with narrow cellular pseudoparaphyses. Neolophiotrema also differs from Purpureofaciens, which has olivaceous, uni-seriate, ellipsoidal ascospores (Dong et al. 2020), while Neolophiotrema has hyaline, overlapping bi-seriate, broadly fusiform ascospores. Refer to Ren et al. (2021).
