 In deposit , the spores appear white . Individual spores are ellipsoid to tear @-@ shaped in profile , obovoid to ellipsoid or roughly cylindric in face or back view , with dimensions of 4 @.@ 8 – 6 @.@ 4 by 2 – 2 @.@ 8 ( sometimes up to 3 @.@ 5 ) µm . They are smooth , inamyloid , and acyanophilous ( unreactive to staining with Melzer 's reagent and methyl blue , respectively ) . The basidia ( spore @-@ bearing cells of the hymenium ) are roughly club @-@ shaped , four @-@ spored , and measure 17 @.@ 5 – 21 by 4 @.@ 8 – 5 @.@ 6 µm . The gills do not have cystidia . The gill tissue is made of hyphae that are interwoven to roughly parallel , and inamyloid . The hyphae are 2 @.@ 8 – 8 @.@ 4 µm in diameter and smooth . The cap tissue is made of interwoven hyphae beneath the center of the cap , but radially oriented over the gills ; it too is inamyloid . These hyphae are 3 @.@ 5 – 8 @.@ 4 µm in diameter , smooth , but have irregularly thickened walls . The cap cuticle is an ixocutis — a gelatinized layer of hyphae lying parallel to the cap surface . The hyphae comprising this layer are 2 @.@ 8 – 6 @.@ 4 µm in diameter , smooth , and thin @-@ walled . They are covered with scattered , short pouch @-@ like outgrowths . The cuticle of the stem is a layer of parallel , vertically oriented hyphae ; the hyphae measure 3 @.@ 5 – 4 @.@ 2 µm , and are smooth , slightly thick @-@ walled , and pale yellowish @-@ brown in alkaline solution . They give rise to a covering of tangled and branched caulocystidia ( cystidia on the stem ) that have multiple septa . The caulocystidia are 2 @.@ 8 – 4 @.@ 8 µm in diameter , smooth , thin walled , and shaped like contorted cylinders . Clamp connections are present in the hyphae of all tissues .
