Two new combinations in the genus Panus (Panaceae, Polyporales) based on morphology and molecular phylogeny

Abstract

Panus is a genus of the order Polyporales with a gilled hymenium. Although Panus was earlier considered as a sub genus of the genus Lentinus, molecular phylogenetic studies support the independent status of the genus. As a result, many species were transferred from Lentinus to Panus. Many more species of Lentinus that are more related to Panus, still await critical taxonomic studies and formal transfers. Morphological and molecular data obtained from L. bambusinus and L. roseus reveal that these are Panus species. Two new combinations in the genus Panus are proposed here.

“…As a result, a phylogenetic tree generated from the ML analysis is shown in Figure 1 . The phylogenetic tree was consistent with the results of previous phylogenetic studies [ 24 , 25 ]. Phylogenetic analyses assigned the genera Cymatoderma and Panus in the family Panaceae.…”

“…Notably, the presence of the smaller basidiospores in P. sribuabanensis clearly distinguishes it from P. caespiticola (5.0–7.5 × 4.0–5.5 μm) [ 19 , 50 ]. Additionally, the narrower size of the basidiospores (4.0–6.0 × 3.0–4.0 μm, Q m = 1.42) in P. sribuabanensis clearly distinguishes it from P. bambusinus (5.0–6.5 × 4.0–4.5 μm, Q m = 1.32) [ 25 , 51 ]. Moreover, the wider size of cheilocystidia (21.0–70.0 × 5.0–9.0 μm) in P. sribuabanensis clearly differs from P. bambusinus (22.0–68.0 × 3.0–5.0 μm) [ 25 , 51 ].…”

Phylogenetically, P. sribuabanensis formed a monophyletic clade and sister taxon to P. bambusinus and P. purpuratus ( Figure 1 ).…”

“…The different characteristics of the microscopic features of P. bambusinus , P. caespiticola , P. sribuabanensis , and P. tephleucus have been mentioned above. In addition, P. bambusinus is distributed only throughout India [ 25 , 51 ], while P. caespiticola was found in Cuba, India, Mali, Mozambique, and Tanzania [ 19 , 50 ]. Furthermore, P. tephroleucus was recorded from Brazil, Cuba, India, and Mexico [ 19 , 22 , 50 ].…”
