Remarks (public):Within the section, Boletus calopus Pers. originally described from Europe (Persoon 1801; Singer 1967; Leclair and Essette 1969; Alessio 1985; Muños 2005) may possibly be related to B. panniformis in appearance. However, it can be differentiated from the present species by a tomentose to nearly smooth pileus without scabrosities, amyloid elements in the pileus trama, and fusiform to lageniform caulocystidia with somewhat thickened walls. Boletus rubripes Thiers from North America (Thiers 1965, 1975; Bessette et al. 2000) seems to be also closely related to B. panniformis, though it has its own distinct characteristics in forming a pale colored, tomentose to appressed-fibrillose pileus and a non-reticulate, smooth stipe. 
Description type:Latin diagnosis 
Description:Boletus panniformis has the characteristics of the brown pileus typically covered overall with small, matted scales, the cyanescent, bitter flesh, the finely reticulate, red stipe, the subcylindrical to fusoid-ventricose caulocystidia, and the habitat in subalpine, coniferous forests. Especially given the natures of its finely reticulate, red stipe and its bitter flesh, B. panniformis can be referable to the section Calopodes Fr. sensu str. Sing. (Singer 1986).
