NOTES: Currently some 60 species are listed under Bacrodesmium (MycoBank), but only one marine species has been described, initially as Trichocladium linderi (Crane & Shearer 1978). Conidial morphology of this species is similar to Trichocladium species, a genus shown to be polyphyletic. Conidia in B. linderi are borne in sporodochia on wood, rather than mononematous and scattered conidiophores as in Trichocladium species (Palm & Stewart 1982). This is a common species locally on mangrove substrata but can easily be confused with Trichocladium nypae. Despite its frequent collection, the species has not been isolated or sequenced, and a molecular study is warranted to determine its phylogenetic relationship as the genus Trichocladium has been shown to be polyphyletic (K.L. Pang, unpublished results). A species frequently recorded in tropical areas, in particular mangroves (Pang et al. 2011, Abdel-Wahab & Bahkali 2012, Borse et al. 2012).
