  2. Nematoctonus brevisporus Thorn & Barron, Mycotaxon 25: 337, 1986 (Ontario, Canada): Hohenbuehelia unguicularis; the anamorph of H. pinacearum is identical.
  3. Nematoctonus campylosporus Drechsler, J. Wash. Acad. Sci. 44: 82, 1954 (Louisiana, U.S.A.): a probable synonym of Hohenbuehelia portegna

  6. Nematoctonus geogenius Thorn & Barron, Mycotaxon 25: 348, 1986 (California, U.S.A.): Consiglio and Setti (in press) show that sequences identified by this name fall in four separate clades, but there are no sequence data for the type collection, BL Thompson 411 (HSC), and the ex-type culture is lost.
  7. Nematoctonus hamatus Thorn & Barron, Mycotaxon 25: 351, 1986 (Ontario, Canada): Hohenbuehelia valesiaca, fide Consiglio and Setti (in press); the anamorph of H. mastrucata is identical.

  9. Nematoctonus leiosporus Drechsler, Phytopathology 31: 779, 1941 (Wisconsin, U.S.A.): Hohenbuehelia leiospora; but a sequence of one isolate named this species but with shorter-than-average conidia has been found to be Hohenbuehelia bonii, fide Consiglio and Setti (in press)

  11. Nematoctonus pachysporus Drechsler, J. Wash. Acad. Sci. 33: 185, 1943 (Maryland, U.S.A.): may represent an earlier name for Hohenbuehelia izonetae fide Thorn (2013), although sequences identified as this name form two separate clades (Koziak et al. 2007).
  12. Nematoctonus robustus F.R. Jones, Trans. Brit. Mycol. Soc. 47: 57, 1964 (Ghana): previously regarded as a synonym of Hohenbuehelia atrocoerulea (Thorn 2013), but likely an independent species.
