 The spores are ellipsoid , occasionally ovoid or obovoid , thin @-@ walled , hyaline , amyloid , and measure 8 – 11 by 5 @.@ 5 – 7 @.@ 5 µm . The spore deposit is white . The basidia ( spore @-@ bearing cells ) are 40 – 65 by 7 – 11 @.@ 5 µm , four @-@ spored , with clamps at their bases . Cheilocystidia ( cystidia on the gill edge ) are occasionally seen as small , club @-@ shaped cells measuring 15 – 35 by 10 – 15 µm , on thin @-@ walled hyphae that are 3 – 7 µm in diameter . The cap cuticle , which is not clearly differentiated from the cap tissue , consists of thin @-@ walled , interwoven hyphae 2 @.@ 5 – 9 µm in diameter . The tissue of the universal veil on the cap consists of more or less parallel and erect rows of roughly spherical , and ellipsoid to broadly ellipsoid cells , up to 78 by 65 µm and spindle- to club @-@ shaped cells up to 125 by 30 µm . These latter cells are terminal or in short , terminal chains , and are borne on moderately abundant , thin @-@ walled , branched , interwoven , sometimes nearly <unk> hyphae , 3 – 9 @.@ 5 µm diameter with a few scattered oleiferous ( oil @-@ containing ) hyphae , 5 – 12 @.@ 5 µm diameter . The distribution of hyphae at the stem base is similar to that on the cap , but with more filamentous hyphae . Clamp connections are present .
