Classification: Ceratocystidaceae, Microascales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Huntiella species occur on a wide range of hosts and are distributed worldwide on Acacia mangium in Indonesia, Eucalyptus obliqua in Australia, E. saligna in South Africa, Mangifera indica in Oman, Picea spinulosa in Bhutan (de Beer et al. 2014), Eucalyptus exserta, Acacia confusa in China (Liu et al. 2018), and Tectona grandis in Thailand. The species are saprobes, weak pathogens and are also commonly found on tree wounds (Mbenoun et al. 2016, Liu et al. 2018). Huntiella chinaeucensis, is illustrated in this entry

Type species: Huntiella moniliformis (Hedgc.) Z.W. de Beer, T.A. Duong & M.J. Wingf.

Other accepted species: Species Fungorum – search Huntiella.
