“…Moncalvo (1996) reported that G. valesiacum and G. lucidum were different species, even G. valesiacum clustered with G. lucidum based on his molecular data. Ganoderma sessile was described from New York, USA by Murrill 1902(Zhou et al 2014 and was treated as a synonym of G. resinaceum by Haddow (1931), while Overholts (1953) considered that G. lucidum should be the correct name for specimens classified as G. sessile. Nobles (1965) pointed out that the specimens classified as G. lucidum in the USA actually represented G. sessile.…”

The genus Ganoderma (Ganodermataceae) has been widely used as traditional medicines for centuries in Asia, especially in China, Korea and Japan. Its species are widely researched, because of their highly prized medicinal value, since they contain many chemical constituents with potential nutritional and therapeutic values. Ganoderma lucidum (Lingzhi) is one of the most sought after species within the genus, since it is believed to have considerable therapeutic properties. In the G. lucidum species complex, there is much taxonomic confusion concerning the status of species, whose identification and circumscriptions are unclear because of their wide spectrum of morphological variability. In this paper we provide a history of the development of the taxonomic status of the G. lucidum species complex. We present a phylogeny for the G. lucidum complex based on multigene analysis with combined 5.8S-ITS rDNA, RPB1, and EF-1α sequence data for 17 taxa of the complex. The taxonomic standing of these species is briefly discussed. Further clarification is, however, required. Type specimens, epitypes, reference collections, fresh collections and vouchered multigene nucleotide sequence data of more informative DNA markers should be used to determine the taxonomy of species in the G. lucidum complex.

“…lucidus was characterized by having a laccate pileus and stipe, which Murrill suspects was the reason for Karsten’s division because only one species was included, G . lucidum [4]. Patouillard revised Karsten’s genus Ganoderma to include all species with pigmented spores, adhering tubes and laccate crusted pilei, which resulted in a total of 48 species classified under the genus Ganoderma in his 1889 monograph [4, 5].…”

Elucidating "lucidum": Distinguishing the diverse laccate Ganoderma species of the United States

Ganoderma is a large, diverse and globally-distributed genus in the Basidiomycota that includes species causing a white rot form of wood decay on a variety of tree species. For the past century, many studies of Ganoderma in North America and other regions of the world have used the name G. lucidum sensu lato for any laccate (shiny or varnished) Ganoderma species growing on hardwood trees or substrates. Molecular studies have established that G. lucidum sensu stricto (Curtis) Karst is native to Europe and some parts of China. To determine the species of the laccate Ganoderma that are present in the United States, we studied over 500 collections from recently collected samples and herbarium specimens from hardwoods, conifers, and monocots. A multilocus phylogeny using ITS, tef1α, rpb1 and rpb2 revealed three well-supported clades, similar to previously reported findings. From the U.S. collections, thirteen taxa representing twelve species were identified, including: G. curtisii, G. lucidum sensu stricto, G. martinicense, G. oregonense, G. polychromum, G. ravenelii, G. sessile, G. tsugae, G. tuberculosum, G. cf. weberianum, G. zonatum, and Tomophagus colossus (syn. G. colossus). The species G. meredithiae is synonymized with G. curtisii, and considered a physiological variant that specializes in decay of pines. The designation G. curtisii f.sp. meredithiae forma specialis nov. is proposed. Species such as G. curtisii and G. sessile, once considered as G. lucidum sensu lato, were found to be divergent from one another, and highly divergent from G. lucidum sensu stricto. Morphological characteristics such as context tissue color and features (e.g. melanoid bands), basidiospore shape and size, geographic location, and host preference were found to aid in species identification. Surprisingly, G. lucidum sensu stricto was found in the U.S., but only in geographically restricted areas of northern Utah and California. These collections appear to have resulted from the introduction of this species into the United States possibly from mushroom growers producing G. lucidum outdoors. Overall, this study clarifies the chaotic taxonomy of the laccate Ganoderma in the United States, and will help to remove ambiguities from future studies focusing on the North American species of laccate Ganoderma.
