Multiple-marker phylogeny and morphological evidence reveal two new species in Steccherinaceae (Polyporales, Basidiomycota) from Asia

Two new wood-inhabiting fungi, Mycorrhaphium subadustumsp. nov. and Trullella conifericolasp. 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, velutinat...

description Two new wood-inhabiting fungi, Mycorrhaphium subadustumsp. nov. and Trullella conifericolasp. 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.
