Spinulum lioui Li Bing Zhang & H.He in Chen et al. (2017: 161) . Figure 2 .

Type:— CHINA. Heilongjiang: Xiaoxing’anling, Hongxing , Hongqi Experimental Forest Farm of Beijing Forestry College [48°19ʹ N, 129°19ʹ E], under Larix forest, 2 September 1963, T.N. Liou et al. 10407 (holotype HIB-0099100 !, isotype PE!) .

Spinulum annotinum with its type from Europe is not distributed in East Asia including Korea and Japan nor in the Himalaya. The phylogenetic analysis of Chen et al. (2022) provides additional evidence that the Asian material of “ Spinulum annotinum ” ( Linnaeus 1753: 1103) A. Haines (2003: 86) should be recognized as S. lioui , separable from the material from Europe and North America ( Chen et al. 2017). We thought S. lioui only occurs in NE China but Chen et al. (2022) showed that the Asian material of “ Spinulum annotinum ” should all be S. lioui . Spinulum annotinum does not occur in Asia except part of the Far East of Russia.
