Neotype of Trichoderma citrinum: W. Gams 4031 (CBS); ex-type culture: CBS 894.85. Holotype of Trichoderma lacteum: DAOM 167644; ex-type culture CBS 853.70. Epitype of Trichoderma lacteum, here designated: W. Gams 4031 (CBS); ex-epitype culture: CBS 894.85. Phylog.: sect. Hypocreanum; anamorph verticillium-like, conidia hyaline. Repres. sequences: tef1: FJ860631, DQ835441; rpb2: FJ179603, AF545561. References: Overton et al. (2006a), Jaklitsch (2011). Note: Hypocrea citrina is a well-known name for a well-known species, particularly in Europe, and has priority over H. lactea. Bissett (1992) erected the name Trichoderma lacteum for the anamorph of H. lactea. The tef1 intron 5 of its ex-type strain CBS 853.70 clearly demonstrates conspecifcity of T. lacteum with T. citrinum. The revised citation of T. lacteum, above, follows the working practice advocated by Hawksworth et al. (2013). Application of the ‘Kew rule’ would favour T. lacteum as the appropriate Trichoderma name for a synonymised H. citrina/H. lactea. However, this would be undesirable, because the inconsistent application of the name H. lactea to a number of diferent taxa could be misleading; for example, “Hypocrea lactea“ sensu Doi (1972) was recently described as T. pseudolacteum by Kim et al. (2013).
