Published: December 2021

Three wood-inhabiting fungal species, , and spp. nov., were collected from southern China, here proposed as new taxa based on a combination of morphological features and molecular evidence. is characterized by the resupinate basidiomata with grandinioid hymenophore having cracked hymenial surface, and ellipsoid basidiospores; is characterized by the annual basidiomata having the hard, brittle hymenophore with cream hymenial surface, and ellipsoid to broadly ellipsoid basidiospores (3.9-5.3 × 3.2-4.3 µm); and is characterized by its grandinioid hymenophore with buff to a pale brown hymenial surface and subglobose basidiospores measuring 2-4.8 × 1.6-4 µm. Sequences of ITS and nLSU rRNA markers of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. The ITS+nLSU analysis of the order Hymenochaetales indicated that the three new species clustered into the family Schizoporaceae, located in genus ; based on further analysis of ITS dataset, was a sister to ; closely grouped with and with high support; while was retrieved as a sister to .

In the ecosystem, wood-inhabiting fungi play an indispensable role in wood degradation and the cycle of substances. They are regarded as the "key player" in the process of wood decomposition because of their ability to produce various enzymes that break down woody lignin, cellulose, and hemicellulose. In this study, four new wood-inhabiting fungal species, , , , and , were collected from southwestern China and were proposed based on the morphological and molecular evidence.

Taxonomy plays a central role in understanding the diversity of life, translating the products of biological exploration and discovery specimens and observations into systems of names that settle a "classification home" to taxa. The ectomycorrhizal basidiomycetes family Thelephoraceae has been understudied in subtropical ecosystems. Many species of Thelephoraceae are important edible and medicinal fungi, with substantial economic value.

A study of corticioid fungi collections from Costa Rica, Panama, Colombia, and Ecuador has resulted in the identification of 26 morphospecies of . These distinctions were made based on characters such as basidiospore size and shape, cystidia morphology, basidioma texture, and hymenial surface configuration. Sequences of rDNA ITS were obtained for 12 of these species, and their relationships to previously known taxa were illustrated using Bayesian and Maximum Likelihood reconstructions of the phylogeny.
