 In North America , Tricholoma pardinum can be confused with T. nigrum and forms of T. virgatum that have more streaked rather than spotted caps . A form of T. pardinum in North America can be nearly white with pale scales , and may be confused with the whitish edible species T. resplendens . Microscopically , the presence of clamp connections sets T. pardinum apart from most other members of the genus , although the similar @-@ looking ( though more tan @-@ coloured ) T. venenatum also has them . According to Alexander H. Smith , T. huronense is closely related , but can be distinguished from T. pardinum by its narrower gills , its tendency to form drops of reddish liquid on the gills and stalk , and an ash @-@ grey and scaly stalk surface .
