Abstract

Dentipellis tasmanica sp. nov. is described and illustrated from Tasmania, Australia based on rDNA evidence and morphological characters. It is characterised by an annual growth habit; resupinate basidiocarps up to 100 cm long; spines cream when fresh and cinnamon when dry, up to 3 mm long and a few glued at tips when dry; distinct white fibrillous to cottony margin; a monomitic hyphal structure with non-amyloid, non-dextrinoid and cyanophilous generative hyphae; the presence of gloeoplerous hyphae and gloeocystidia which become dark blue in Melzer’s reagent; the presence of chlamydospores in the subiculum and rough basidiospores measuring 3.5-4.5 × 2.4-3.2 µm. A molecular study based on the combined ITS (internal transcribed spacer region) and 28S (the large nuclear ribosomal RNA subunit) dataset supports the new species in Dentipellis. A key to species of Dentipellis sensu stricto is provided.
