Deskripsi

<i>Anomoloma</i> is a cosmopolitan poroid wood-decaying genus, belonging to the Amylocorticiales. During a study on polypores, two new species of <i>Anomoloma</i> were found in Eurasia, and they are described as <i>A. denticulatum</i> and <i>A. eurasiaticum</i>. To examine the phylogenetic relationships among species of <i>Anomoloma</i>, we analyzed nuclear ribosomal sequence data from the ITS regions and the LSU gene. The result demonstrates that <i>A. denticulatum</i> and <i>A. eurasiaticum</i> are independent species that belong to the <i>Anomoloma</i> genus. Both new species share the principal characteristics of the genus, but <i>Anomoloma denticulatum</i> is characterized by extensive white rhizomorphs spreading under the whole fruiting body, angular pores measuring 1–2 per mm, distinctly lacerate to dentate dissepiments and basidiospores of 3.5–4.3 × 2–2.5 μm. <i>Anomoloma eurasiaticum</i> is characterized by bearing plenty of large crystals on the mycelia and growth on <i>Picea</i> in high altitude areas. A key to the accepted species of <i>Anomoloma</i> worldwide is provided.
