Lentinula edodes (Berk.) Pegler, or shiitake in the vernacular, is a basidiomycete of the family Tricholomataceae. Shiitake ranks second in U.S. mushroom production after the button mushroom (Agaricus bisporus [Lang.] Imbach) (USDA, 2007), and second in world mushroom production after the button mushroom (Agaricus bisporus [Lang.] Imbach)  (Chang, 2005).  Shiitake are sold either fresh or dried and are one of the most important fungal constituents of the cuisine of countries such as Japan and China.  Shiitake continue to gain popularity in Western countries.  In the United States alone, shiitake consumption increased from 1,343 metric tons (3 million pounds) in 1993 to 3,039 metric tons in 2006 (6.8 million pounds) (USDA, 2007).  Extant relatives of L. edodes are also comestible and contribute to a diverse genetic pool for the genus Lentinula Earle.

 

      Shiitake has been known generically as Lentinus Fr. and Collybia (Fr.) Staude among many other names (Pegler 1975a, 1975b).  In the early 1980’s, Pegler (1983) assigned shiitake to the genus Lentinula.  Currently, there are six species that are generally recognized in the genus Lentinula, three (L. edodes, L. lateritia [Berk.] Pegler, and L. novaezelandiae [Stev.] Pegler) are of Asia-Australasian distribution, while the remaining three (L. boryana  (Berk. & Mont.) Pegler, L. guarapiensis (Speg.) Pegler, and L. raphanica (Murrill) Mata & R.H. Petersen) are distributed in the Americas.  Recent work has suggested that the Asia-Australasian-distributed species comprise a single biological species as evidenced by their ability to interbreed (Shimomura et al. 1992; Guzman et al. 1997), with the indication that the species could all be classified as L. edodes according to a biological species approach.  However, Hibbett and others (Hibbett 1992, Hibbett et al. 1995, Hibbett and Donohue 1996, Hibbett et al. 1998) advise against a single Asia-Australasian biological species classification and advocate distinct phylogenetic species to delineate the unique, divergent genetic populations of shiitake possibly existing as monophyletic groups.  It is clear that L. edodes and L. boryana remain separate biological species, unable to interbreed (Mata and Guzmán 1989, Guzman et al. 1997).  Unfortunately, no living specimens of L. guarapiensis are available for study, so our understanding of the Lentinula representatives distributed in the Americas is limited.
