Abstract

Mycorrhaphoides gen. nov. and Mycorrhaphoides stalpersii sp. nov. are described and defined based on morphological details and phylogenetic inference of a hydnoid macrofungus collected in Acharya Jagadish Chandra Bose Indian Botanic Garden, Howrah (India). It is characterized by stipitate basidiomata with duplex context in stipe, presence of multi-clamped septa, and smooth and hyaline cystidia.

Mycorrhaphoides Hembrom, K. Das & Hallenb. gen. nov.
 MycoBank: 816805. 

Type: Mycorrhaphoides stalpersii Hembrom, Nilsson, A. Parihar, K. Das, A. Baghela & S.K. Singh.

Etymology:  The genus name is motivated by the fact that the new genus shares some similarities with Mycorrhaphium, another hydnoid genus.

 MycoBank: MB 816806.

Type: India; West Bengal, Howrah, AJCBIBG, near bicentenary gate, 22 ° 33 ′ 49.6 ″ N, 88 ° 17 ′18.5 ″ E, 13 m a.s.l., on base of living tree trunk of Tamarindus indica L., 24 Oct 2015, K. Das, M.E. Hembrom & Parihar, KMA-15-45 (holotype: CAL, isotype: AMH).

Etymology:  The species name is chosen to commemorate Dr. Joost A. Stalpers for his contribution to hydnoid mycology.
