“…Reid and Inonotus porrectus Murrill with phylogenetic evidence. Dai (2010) included some species with resupinate basidiocarps and/or hymenial setae into Fulvifomes without phylogenetic evidence. and Hattori et al (2014) accepted the circumscription of Fulvifomes as a genus by the combination of annual to perennial and effused-reflexed, sessile to substipitate basidiocarps with solitary to imbricate pilei and an homogeneous or duplex context, a monomitic to dimitic hyphal system, lack of hyphoid and hymenial setae, and subglobose to ellipsoid, yellowish to brown, slightly thick to thick-walled basidiospores.…”

Two new species of Fulvifomes are described from samples collected in America based on morphological characteristic and molecular evidence: F. centroamericanus Y.C. Dai, X.H. Ji & Vlasák, sp. nov. and F. krugiodendri Y.C. Dai, X.H. Ji & Vlasák, sp. nov. The former is characte rized by perennial and sessile basidiocarps, a concentrically sulcate and cracked pileal surface, a homogeneous context, small pores (7-9 per mm), a dimitic hyphal system, subglobose, yellowish and thick-walled basidiospores 4.3-5 × 4-4.5 μm. Macroscopically it resembles F. merrillii, which differs in having larger basidiospores (5-6 × 4-5 μm). F. centroamericanus is similar to F. robiniae in sharing applanate basidiocarps and subglobose, yellowish and thick-walled basidiospores 3.9-4.5 × 3.7-4.2 μm, whereas F. robiniae has larger basidiospores (5-6 × 4.5-5 μm). In nuclear large subunit rDNA (nLSU) and internal transcribed spacer (ITS) based phylogenies, the two new species formed two distinct lineages in the Fulvifomes clade.

“…Fomitiporia belongs to the family Hymenochaetaceae (Hymenochaetales) and is characterized by its hyaline, subglobose to globose and thick-walled basidiospores with strongly cyanophilous and dextrinoid reactions [79]. This genus was split from Phellinus s.l.…”

“…Recent molecular phylogeny work has transferred some species of this genus to Inocutis Fiasson & Niemelä, Inonotopsis Parmasto, Mensularia Lázaro Ibiza and Onnia P. Karst., while several species that used to belong to Phellinus were combined into Inonotus [15,79]. At the moment, the reduced size genus includes several well-known medicinal species, such as I. baumii (Pilát) T.

[82,90], which have been used in China since ancient times, according to traditional folklore. These medicinal species differ from other species of Inonotus mainly in their perennial hard woody basidiocarps and in their dimitic hyphal system in trama, from a morphological perspective [79]. With respect to phylogeny inferred from nLSU or ITS combined mt-SSU sequences, these species form a strongly supported clade and have been tentatively named as a medicinal group [70] that is isolated from other species [15,91].…”

This study addressed three important aims: (1) undermining the previously obtained raw data about wood-decaying fungi (WDF) distribution and continuously investigating permanent plots to address certain scientific questions in ecology, (2) resolving the higher-level phylogeny of WDF with the help of multiple loci, and (3) testing and estimating the medicinal values of species that are closely related to well-known medicinal species. More than 1200 species and 2469 strains of WDF in China were identified from 28908 specimens collected from a series of field investigations. Using these materials, studies in multiple disciplines, such as ecology, taxonomy and phylogeny, and medicine, have been performed. With respect to ecology, the diversity of wood-decaying polypores significantly differed among a boreal forest zone, a temperate and warm temperate forest zone, and a tropical and subtropical forest zone. For instance, from north to south, the number and proportion of brown-rot species and the proportion of species found on fallen trunks were both decreased. The ecological patterns of wood-decaying polypores on gymnosperm and angiosperm trees were also explored by a case study in Northeast China. Although the total species richness was similar between the two tree groups, several other characteristics were significantly different, such as community structure and richness in certain substrates. The taxonomy and phylogeny of wide samples were referred to and their phylogenetic positions were resolved or at least partially established. In particular, phylogenetic knowledge about four genera, Fomitiporia, Ganoderma, Inonotus and Perenniporia, which include medicinal species, was essential for further research to determine the medicinal values of these types of fungi. Among these medicinal species, we mainly focused on Inonotus obliquus for its medicinal purposes. Polyphenols, polysaccharides and lanostane-type triterpenoids, extracted from the sterile conk of this species, could dramatically decrease levels of free radicals, DPPH and hydroxyl radicals, respectively. The metabolic profiles (both production and composition) of cultured I. obliquus mycelia could be altered by co-culture with other medicinal species or by induction of S-nitrosylation and denitrosylation, which may enhance the antioxidant capacity of I. obliquus.

Optimized production and safety evaluation of hispidin‐enriched Sanghuangporus sanghuang mycelia

Phellinus linteus, also known as the sanghuang mushroom, is a medicinal mushroom that has been recognized as beneficial to health for more thousands of years.Among its diverse valuable secondary metabolites, the yellow-brown styrylpyrone pigment hispidin has garnered significant attention due to its various pharmacological effects. However, recently after detailed morphological and molecular phylogenetic studies, the correct scientific name of the true sanghuang strains was shown not to be P. linteus but Sanghuangporus sanghuang. As the incorrect binomial name P. linteus has long been misleadingly referred, there is a need to evaluate the safety of S. sanghuang. Moreover, the growing conditions can impact the secondary metabolite profile of the fungi. Hence, this study is the first to optimize hispidin production and to investigate the genotoxic and oral toxic effects of hispidin-enriched S. sanghuang mycelia. In order to induce the biosynthesis of hispidin, 15 different culture media consisting of five carbon sources, five nitrogen sources, and five initial pH conditions were screened. Glucose and yeast extract at an initial pH of 5 were found to be the most suitable carbon and nitrogen sources, respectively, for the optimal growth and production of hispidin. Moreover, the production of hispidin was 3 mg/g in a 20-ton bioreactor under optimal conditions. Furthermore, the ames test, in vitro chromosome aberration test, acute oral toxicity test, and bone marrow micronucleus test were used to detect toxicological properties of 3 mg/g hispidin-enriched S. sanghuang mycelia. In all tests, there was no statistically significant difference between the mycelia and the negative control. Based on the results obtained, the present study demonstrates that 3 mg/g hispidin-enriched S. sanghuang mycelia has a very low order of toxicity, which supports its safety for human consumption.
