Notes – The genus was reported from a fallen tree and from a trunk of Elaeocarpus in montane forest in Papua New Guinea. The genus was placed in Dacampiaceae in the original publication because of similarities with the genus Sinodidymella. It was transferred to Teichosporaceae by Barr (2002). Since Leptocucurthis strongly differs from Dacampia notably by a saprobic life style (or parasitic of tree trunks?), ascomata with a slit-like to stellate with 3-6 radiate splits ostiole, unbranched pseudoparaphyses, long fusiform to cylindrical hyaline 1-septate ascospores, it might be better placed in the Hysteriaceae that produce a slit-like opening to release the spores.
Type species: Leptocucurthis quadrata Aptroot, in Aptroot & van Iperen, Nova Hedwigia 67 (3–4): 485 (1998).
Other accepted species: Species Fungorum – search Leptocucurthis.
