Lycoperdon subcretaceum – a puffball new to Europe found in Norway

• The puffball Lycoperdon subcretaceum is reported new to Norway and Europe. The material was collected in 2009 in the county of Sør-Trøndelag in Central Norway. A morphological study of the collected sample indicated affinity with the North American species Calvatia subcretacea Zeller (syn. Handkea subcretacea (Zeller) Kreisel). Sequencing of the complete ITS and partial LSU of the Norwegian collection was performed. The ITS2 region was compared with sequences deposited at GenBank using BLAST search. A 100% match was obtained with an American sequence of Handkea subcretacea. The morphology of the Norwegian sample fits the original description of Calvatia subcretacea and the collection is described and illustrated. Based on the results from the molecular phylogenetic analyses and morphological characteristics a transfer of Calvatia subcretacea to the genus Lycoperdon is suggested and the new combination Lycoperdon subcretaceum (Zeller) Jeppson & E. Larss., comb. nov. is proposed.
