Rhodoantrodia purpurascens is characterized by the corky basidiomata with a pale lilac to lavender pore surface, a dimitic hyphal system with clamped generative hyphae, and broadly ellipsoid basidiospores. Steccherinum wumengshanense is characterized by the corticoid basidiomata having a white to cream hymenial surface, a monomitic hyphal system with clamp generative hyphae, and ellipsoid basidiospores. Full descriptions, photo plates and phylogenetic analysis results of the new species are provided.

The wood-inhabiting fungi play an integral role in wood degradation and the cycle of matter in the ecological system. They are considered as the “key player” in wood decomposition, because of their ability to produce all kinds of enzymes that break down woody lignin, cellulose and hemicellulose. In the present study, three new wood-inhabiting fungal species, Steccherinum fissurutum, S. punctatum and S. subtropicum spp. nov., collected from southern China, are proposed based on a combination of morphological features and molecular evidence. Steccherinum fissurutum is characterized by the resupinate, subceraceous basidiomata with cracked hymenophore, a monomitic hyphal system with clamped generative hyphae and cylindrical basidiospores; S. punctatum is characterized by the annual, punctate basidiomata with leathery hymenophore, cylindrical, strongly encrusted cystidia and ellipsoid basidiospores (3.6–4.5 ×2.6–3.4 µm); S. subtropicum is characterized by its effuse-reflexed basidiomata, a odontioid hymenophore with pink to lilac hymenial surface and ellipsoid basidiospores measuring as (2.8–3.4 × 2.0–2.7 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 family Steccherinaceae indicated that the three new species clustered into the genus Steccherinum. Based on further analysis of ITS+nLSU dataset, the phylogenetic analysis confirmed that S. subtropicum was sister to S. enuispinum; S. fissurutum formed a monophyletic lineage; S. punctatum grouped with a clade comprised S. straminellum and S. ciliolatum.

Two new wood-inhabiting fungi from China, Steccherinum juniperi and
S. incrustans, in the family Steccherinaceae are described and illustrated based
on morphological and molecular analyses. The species S. juniperi was found
growing on the rotten wood of Juniperus in Qinghai Province, China, while S.
incrustans was collected on rotten angiosperm wood in Yunnan Province, China.
The characteristics of S. juniperi include annual, resupinate basidiomata with a buf
yellow fresh pore surface that becomes apricot orange when bruised, angular
pores of 3–6 per mm, subicular generative hyphae sometimes covered with
crystals, the presence of encrusted skeletocystidia in tube trama only, fusiform
to slim clavate cystidioles, and ellipsoid basidiospores measuring as 3–4 × 2–
3µm. The characteristics of S. incrustans include annual, resupinate basidiomata
with a buf yellow or pinkish buf to clay buf dried pore surface, angular pores
(8–10 per mm), generative hyphae in trama frequently covered with crystals, the
presence of encrusted skeletocystidia in tube trama and hymenium, and ellipsoid
basidiospores(3.5–4.5 × 2.5–3.5µm). Phylogeneticanalysis based on a combined
2-locus dataset [ITS1-5.8S-ITS2 (ITS) + nuclear large subunit RNA (nLSU)] shows
that the two species are members of Steccherinum, and they are compared
with morphologically similar and related species of this genus, respectively. In
addition, two new combinations from Junghuhnia, transferred to Steccherinum
as S. austrosinense and S. nandinae, are proposed based on examination of their
type materials and phylogenetic analysis.
