Lactifluus indovolemus sp. nov. and two new records in the Lactifluus volemus complex (Basidiomycota, Russulaceae) from India

Abstract

Macrofungal exploration in the West Kameng district of Arunachal Pradesh followed by a thorough examination of collected wild agaricoid mushrooms uncovered one novel species (described here as Lactifluus indovolemus sp. nov.) and two more species (L. acicularis and L. crocatus) new to India. Detailed morphological description, supporting illustrations and a nrITS‐based phylogenetic reconstruction is presented. A comparison with allied species is also provided.

A short story of nearly everything in Lactifluus (Russulaceae)

“…However, the genus also appears to be well-represented in South America, as new species are being discovered since more South American habitats are being explored ( Henkel et al 2000 , Miller et al 2002 , Smith et al 2011 , Sá et al 2013 , Sá & Wartchow 2013 , Crous et al 2017 , Delgat et al 2019 , Delgat et al 2020 , Duque Barbosa et al 2020 ), and the majority of the proposed South American Lactarius species turns out to belong in Lactifluus ( Pegler & Fiard 1979 , Singer et al 1983 , Miller et al 2002 ). Since 2010, 78 new Lactifluus species have been described: 34 from Asia ( Stubbe et al 2012a , Van de Putte et al 2012 , Wang et al 2012 , Wang et al 2015 , Morozova et al 2013 , Latha et al 2016 , Li et al 2016 , Uniyal et al 2016 , Zhang et al 2016 , Das et al 2017 , Hyde et al 2017 , Song et al 2017 , De Crop et al 2018 , Liu et al 2018 , Song et al 2018 , Bera & Das 2019 , Dierickx et al 2019a , b , Phookamsak et al 2019 ), 16 from Africa ( De Crop et al 2012 , Maba et al 2014 , Maba et al 2015a , b , De Crop et al 2016a, b , De Crop et al 2019 , Delgat et al 2017 , De Lange et al 2018 ), 20 from the Neotropics ( Miller et al 2012 , Montoya et al 2012 , Sá et al 2013 , Sá &...…”
