 Inocybe saliceticola was first described in 2009 by Jukka Vauras and Katri Kokkonen in the journal Karstenia , based on around 20 specimens from Finland , the majority of which were collected by the authors . The holotype was collected from the shore of lake Pahakala , near Nurmes . The specific name saliceticola is in reference to the fact that the species grows among willow ( Salix ) . Within the genus Inocybe , I. saliceticola belongs to the section Marginatae , as defined by Rolf Singer . The section has been defined in several ways . It was established in 1933 by Robert Kühner , who identified two key characteristics : a stem which does not feature a cortina ( a fragile , cobweb @-@ like partial veil ) but is entirely covered by cystidia , and the presence of a marginate " bulb " at the base of the stem . Singer emended the section in 1986 to take into account that a bulb is not always present . A slightly different infrageneric taxonomy was offered by Thom Kuyper in 1986 . He , like Singer , grouped Marginatae under Inocybe subg . Inocybe , but he labelled it a " supersection " . However , phylogenetic studies have indicated that neither Singer 's section Marginatae nor Kuyper 's " supersection " Marginatae truly form monophyletic groups , but that Singer 's section comes closer to doing so . Species within Marginatae similar to I. saliceticola include I. obtusiuscula , I. dunensis , I. salicis @-@ herbaceae , I. substellata , I. praetervisa , I. salicis and I. mixtilis . These species are all known to associate with willow , and all have macroscopic similarities .
