Boletus michoacanus should be listed as Endangered (EN) based on the criteria A3c because its main habitat, the high mountain Abies religiosa forest, is expected to decline 87% within the next fifty years due to global warming.

Boletus michoacanus belongs to Secc. Luridi sensu Singer 1986. It is distinguished from the rest of the species on the section by its robust fruit bodies, pink to reddish aerolated pileus, orange to reddish pores, and concolorous stipe fully reticulated. Its context is yellow and becomes blue. Its ascription to Rubroboletus is been confirmed by molecular studies.

This fungus is strongly associated with an endemic conifer on central Mexico. Its host, Abies religiosa, populations will decline 87% in the next 50 years due to global warming. In consequence the fungus is severely endangered. It has potentially 50 isolated and fragmented subpopulations that will decline with its habitat loss.

Endemic to central Mexico in the Abies religiosa temperate forests of the Transmexican Volcanic Belt. On an altitude range of 2800 to 3000.

GBIF (2019) register 11 occurrences in five subpopulations. This large Bolete is known from five localities. All subpopulations are associated to Abies religiosa forest. Within the Abies religiosa forests in the center of Mexico may be a ten fold (50) estimated number of subpopulations. The few existing records do not seem to be a result of under-sampling duet o large and conspicuous fruit-bodie of the fungus. As it is strongly associated with Abies religiosa and this tree is severely endangered by climate change, Boletus michoacanus population will suffer a continuous decline in the near future.

Subgregarious in Abies religiosa leaf-litter, on an elevation range of 2800 a 3100 m.

All subpopulations of Boletus michoacanus are associated with Abies religiosa forests.  Abies religiosa forests are subjected to land cover-change and illegal timber extraction. In addition, this vegetation is severely threatened by global warming; it has been estimated that by 2060, A. religiosa populations will decline by 87%  (Miranda-Aragón et al., 2012; Sáenz-Romero et al., 2016; Sáenz-Romero, Rehfeldt, Duval, & Lindig-Cisneros, 2012).
The localities in Sengio, el Chico and Zempoala are natural preserves, however they are close to large cities and subjected to urbanization and pollution.

Mitigation of global warming and assisted migration of Abies religiosa.

To monitor and map subpopulations. To conduct phylogenetic analyses to allocate the species in the new genus Rubroboletus.

Non edible, considered toxic in el Chico, Hidalgo.
