Inocybaceae

There are 1335 Inocybe collections made by Oluna Ceska from BC listed in the online database of the UBC Beaty Museum Fungal Collections; for about half of these, ITS sequences have been entered into GenBank by students supervised by Mary Berbee. Because of the depth of these data, we were able to identify Inocybe cf. nitidiuscula (Britzelm.) Lapl., 1894 , Inocybe cf. griseolilacina J.E. Lange, 1917 , and Inocybe cf. xanthomelas Boursier & Kuhner, 1933 from ECMs of Garry oak as 100% matches with sequences from sporocarps collected by Oluna Ceska under Garry oak on Vancouver Island. The fourth Inocybe species detected from ECMs in this study was a 100% match with the holotype of Inocybe suecica Vauras & E. Larss., 2016 , which was collected under Q. robur in Västergötland, Sweden ( Vauras and Larsson 2016) and is a first report of this species in BC. More work will need to be done to clarify the correct names for these species in BC;

in fact, Matheny and Kudzma (2019) point out that Index Fungorum recognizes 1050 accepted names of species in Inocybe . Seress et al. (2016) indicated that ITS sequences in public databases that are assigned to I. nitidiuscula belong to at least five different, phylogenetically separated lineages with more than 3% sequence differences. Inocybe griseolilacina is a European species associated with oak ( Bandini et al. 2021). Inocybe xanthomelas was also originally described from Europe but the name is commonly applied, rightly or wrongly, to collections from both western and eastern North America (https://www.gbif.org/species/2527910).
