Variability of size, color, etc. of members of this group is so big that several authors claim they can hardly be determined in the field. Microscopy is needed. Pluteus pouzarianus is distinguished from other options, particularly from common Pluteus cervinus s.s., by: about 40% of hypha in pileipellis having clamps and it grows exclusively on conifer wood. Usually it has (in average) grayer cap and it is of somewhat smaller size. It seems, traits of the find fit well to literature.There were two pilei present in this find. Pilei diameter 4 and 4.5 cm, surface velvety-waxy for palpation, cuticle peels off easily; stipe 4.5 and 5 cm tall, diameter in the middle 6 and 6.5 mm, 'bulbous'; smell faint, lightly on radish; taste faint, slightly mushroomy and on radish; SP abundant, pinkish-ocher, oac651.Spores smooth.

Dimensions: 41.2 [53 ; 58.6] 70.3 x 11.9 [15 ; 16.5] 19.6 microns; Q = 2.6 [3.4 ; 3.8] 4.5; N = 27; C = 95%; Me = 55.8 x 15.7 microns; Qe = 3.6.
