Eight remarkable specimens of hydnoid corticioid fungi from the genus Steccherinum were collected in the Black Forest National Park, Southern Germany. After preliminary attributing these specimens to either Steccherinum tenuispinum or S. gracile, two other possible names for this species were identified after literature and type specimen studies. The oldest of the four available names is Hydnum pudorinum introduced by Fries in 1828. In this paper the new combination Steccherinum pudorinum (Fr.) Spirin & Popa comb. nov. is proposed for the species under focus, and three other names are put to its synonyms. Additionally, we succeeded in cultivating a strain that produces fertile fruiting bodies. The German vernacular name "Zarter Resupinat-stacheling" is proposed for the new combination and morphology and ecology of the species are discussed. The species has a wide distribution, but is overall rare and restricted to old-growth forests. In Germany, there is currently only a single record outside the Black Forest National Park and the Swabian Alps, which are also the westernmost records known to date, namely from the Bavarian Forest National Park. The latter record is also the earliest record of the species in Germany.
... It is a cosmopolitan genus characterized by a combination of resupinate to effused-reflexed or pileate basidiome with a membranaceous consistencey, hymenophore odontioid to hydnoid, a dimitic hyphal structure with clamp connections or simple-septate generative hyphae, cystidia numerous, strongly encrusted in the obtuse apex, basidia subclavate and basidiospores hyaline, thin-walled, smooth, ellipsoid to subcylindrical, acyanophilous and negative in Melzer's reagent (Fries, 1821;Gray, 1821;Bernicchia and Gorjoń, 2010). So far, about 80 species have been accepted in this genus worldwide (Fries, 1821;Banker, 1906;Banker, 1912;Cunningham, 1958;Snell and Dick, 1958;Lindsey and Gilbertson, 1977;Ryvarden, 1978;Lindsey and Gilbertson, 1979;Burdsall and Nakasone, 1981;Melo, 1995;Legon and Roberts, 2002;Yuan and Dai, 2005a;Spirin et al., 2007;Hjortstam and Ryvarden, 2008;Bernicchia and Gorjoń, 2010;Miettinen et al., 2012;Yuan and Wu, 2012;Miettinen and Ryvarden, 2016;Westphalen et al., 2018;Liu and Dai, 2021;Westphalen et al., 2021;Wu et al., 2021a;Wu et al., 2021b;Dong et al., 2022).

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, Mycorrhaphium subadustum sp. nov. and Trullella conifericola sp. nov. , are proposed and described from Asia based on ITS, nrLSU and tef1 molecular phylogeny and morphological characteristics. Mycorrhaphium subadustum is characterized by a stipitate basidiocarp, velutinate pileal surface concentrically zoned, hydnoid hymenophore, a dimitic hyphal system in spine trama and monomitic in context, absence of gloeocystidia, presence of cystidioles and the non-amyloid, cylindrical to ellipsoid basidiospores. Trullella conifericola is characterized by a laterally stipitate basidiocarp with flabelliform to semicircular pileus, hirtellous pileal surface with appressed coarse hair and concentrically zoned and sulcate, tiny pores (10–12 per mm), a dimitic hyphal system, absence of any type of cystidia, short clavate basidia and thin-walled, smooth, cylindrical to allantoid basidiospores. Phylogenetic analyses based on a three-marker dataset were performed using maximum likelihood and Bayesian inference methods. The two new species formed isolated lineages with full support in Steccherinaceae. The distinguishing characters of the two new species as well as allied species are discussed, and a key to species of Mycorrhaphium is provided.

In this study, taxonomic and phylogenetic analyses of Junghuhnia were performed. Three new species were characterised according to morphological characteristics and molecular phylogenetic analysis using ITS and nLSU sequences. They are J. austrosinensis sp. nov. , J. nandinae sp. nov. and J. subcollabens sp. nov. Junghuhnia austrosinensis is characterised by resupinate, thin basidiomata with white to buff-yellow hymenophore, small pores (9–11 per mm), clamped generative hyphae possessing hymenial cystidia, ellipsoid basidiospores (2.5–3 × 1.7–2 µm) and growth on fallen bamboo or angiosperm branch. Junghuhnia nandinae is characterised by resupinate basidiomata with pink to salmon pores and a distinct white margin, clamp generative hyphae, interwoven tramal hyphae, ellipsoid basidiospores measuring 2.6–3.2 × 1.8–2 µm and growth on Nandina domestica . Junghuhnia subcollabens is characterised by resupinate basidiomata with pale salmon to brownish vinaceous hymenophore, small pores (10–12 per mm), generative hyphae with simple septa and clamp connections, interwoven tramal hyphae, lunate basidiospores measuring 2.9–3.4 × 1.6–1.8 µm and thriving on rotten wood of angiosperms.

... V.), výsledek molekulární analýzy však byl velmi překvapivý. Sekvenování vzorku S. gracile totiž potvrdilo nejenom předpokládanou rozdílnost vůči druhu S. ochraceum, ale sekvence byly to tožné s druhem S. tenuispinum, nedávno popsaným ruskými mykology (Spirin et al. 2007). Ukázalo se tedy, že i ruští mykologové správně vytušili rozdílnost této houby od S. ochraceum, při popisu svého nového druhu však opomněli důsledně prověřit všechna starší jména, která by mohla přicházet v úvahu. ...

New records of the rare corticioid fungus Steccherinum gracile (Pilát) Parmasto are published from the territory of Czechia, Slovakia and western Ukraine. All collections were made in strictly protected old/growth forests, mostly on fallen dead trunks or branches of fir (Abies alba), less often on deciduous trees (Fagus sylvatica, Ulmus glabra). A brief description of this species is given and the most important differential characters of similar species are discussed. Molecular analysis has confirmed the identity of Steccherinum gracile with the recently described species Steccherinum tenuispinum Spirin, Zmitr. et V. Malysheva, which is thus included in the synonymy.
... In nature T. hirsuta, C. caperata, J. nitida and S. bourdotii do not exhibit narrow selectivity to the host-tree and colonize predominately dead wood of angiosperms. [11,[44][45][46]. T. hirsuta is a wound primary xylotrophic basidiomycete. ...
White-rot basidiomycetes from the poorly studied residual polyporoid clade of Polyporales order Junghuhnia nitida (Pers.) Ryvarden and Steccherinum bourdotii Saliba & A. David grow as secondary xylotrohps on well decomposed woody materials. The main objective of the current study was to compare oxidative potential, growth, production of oxidative enzymes and laccase properties of J. nitida and S. bourdotii with that of typical primary xylotrohps Trametes hirsuta (Wulfen) Lloyd and Coriolopsis caperata (Berk.) Murrill, belonging to the core polyporoid clade. For the first time we report species J. nitida and S. bourdotii as active laccase producers. New laccases from J. nitida and S. bourdotii were purified and characterized. They had an identical molecular weight of 63 kDa and isoelectric points of 3.4 and 3.1, respectively. However, the redox potential of the T1 copper site for both J. nitida (610 mV) and S. bourdotii (640 mV) laccases was lower than those for T. hirsuta and C. caperata laccases. The new laccases showed higher temperature optima and better thermal stability than T. hirsuta and C. caperata laccases. Their half-lives were more than 40 min at 70 °C. The laccases from J. nitida and S. bourdotii showed higher affinity to syringyl-type phenolic compounds than T. hirsuta and C. caperata laccases. The oxidative potential of studied fungi as well as the properties of their laccases are discussed in terms of the fungal life-style.
Two new wood-inhabiting fungal species, Steccherinum hirsutum and S. yunnanense spp. nov., are proposed based on a combination of morphological features and molecular evidence. Sequences of internal transcribed spacer and large subunit region of nuculear ribosomal RNA gene of the studied samples were generated, and phylogenetic analyses were performed using maximum likelihood, maximum parsimony and bayesian inference methods. Steccherinum hirsutum is characterized by an annual growth habit, stipitate basidiocarps with scarlet to red, odontioid hymenial surface, a dimitic hyphal system with clamped generative hyphae negative in Melzer's reaction, and acyanophilous basidiospores measuring 2.5-3.5 × 1.5-2.5 µm. Steccherinum yunnanense is distinguished by resupinate basidiomata with odontioid hymenial surface, a dimitic hyphal system with clamped generative hyphae, strongly encrusted cystidia and ellipsoid, hyaline, thin-walled, smooth basidiospores (3.5-4.5 × 2-3.5 µm). The phylogenetic analyses comfirmed that two new species nest in Steccherinum, in the residual polyporoid clade.
