Tuberaceae

Ten clades in the genus Tuber were detected associated with Q. garryana in BC and Oregon. In this study, we detected two taxa forming ECMs with Garry oak, Tuber beyerlei Trappe, Bonito & G.Guevara and a putatively novel taxon within the Tuber candidum Harkn., 1899 complex (Gregory Bonito, pers. comm.). This novel taxon has been detected at two locations in BC (Lazo Road and the NRL) but nowhere else. We are not aware of collections of fruiting bodies formed by this fungus. The type material of T. beyerlei was collected under Douglas-fir in Oregon ( Guevara et al. 2013) and has previously reported from ECMs of Quercus robur L. in truffle orchards in BC as too was Tuber menseri nom. prov. ( Berch and Bonito 2016) and from ECMs of Garry oak in Oregon but not previously with Garry oak in BC. Our phylogenetic analysis suggests that T. menseri nom. prov. is a species complex, for example including Tuber spp. 22 and 23 ( Bonito et al. 2010). Many more Tuber species have been associated with Garry oak in Oregon than

in BC, perhaps because there has been greater search effort for fruiting bodies and ECMs with Garry oak in Oregon than in BC.
