Magnibotryascoma was introduced by Thambugala et al. (2015), to accommodate M. uniseriatum as the type species, which was previously known as Misturatosphaeria uniseriata (Mugambi & Huhndorf 2009). Magnibotryascoma species have a cosmopolitan distribution as woody-based saprobes on Clematis vitalba, Malus halliana, Ribes sanguineum, Robinia pseudoacacia, Salix sp., and Vaccinium myrtillus from Belgium, China, Germany, Norway and the United Kingdom (Jaklitsch et al. 2016, Hyde et al. 2017, Phukhamsakda et al. 2020, Mortimer et al. 2021). The sexual morph of Magnibotryascoma is characterized by erumpent to superficial ascomata lacking a subiculum and fusiform to elliptical and guttulate ascospores and the asexual morph has pycnidial conidiomata featuring aseptate and brown conidia (Jaklitsch et al. 2016, Hyde et al. 2017, Phukhamsakda et al. 2020, Tennakoon et al. 2021). There are four Magnibotryascoma species in Index Fungorum (2022).

Type species: Magnibotryascoma uniseriatum (Mugambi, A.N. Mill. & Huhndorf) Thambug. & K.D. Hyde, in Thambugala et al., Fungal Diversity 74: 249 (2015).

Other accepted species: Species Fungorum – search Magnibotryascoma.
