SPECIES STATUS SHEET

SCIENTIFIC NAME: Boletus subcaerulescens

COMMON NAME: A Species of Porcini Mushroom

CURRENT MINNESOTA STATUS: None

PROPOSED MINNESOTA STATUS: Special Concern

BASIS FOR PROPOSED MINNESOTA STATUS: Boletus subcaerulescens is reported as occasional to locally common from eastern Canada, south to western New York and Michigan, but the species’ geographic range limits have not been determined. Within Minnesota, this mushroom species has been reported from only two sites: along Amity Creek in Lester Park, Duluth, southern St. Louis County and in a red pine plantation near the Willow River, General Andrews State Forest, Pine County. It is a mycorrhizal forest species that fruits on the ground in association with northern conifers and hardwoods, and was first reported in association with Pinus banksiana, but more recently with Pinus sylvestris, , birch and aspen.

In Minnesota, Boletus subcaerulescens is associated with Pinus resinosa or near Picea glauca, Abies balsamea, Pinus strobus, and Betula sp. In our area, it is reported to fruit from mid July until early October. This species is easily mistaken for Boletus edulis but is distinguishable by cap and stipe colors, and tubes that bruise blue. Boletus subcaerulescens has not been observed beyond the two known locations in Minnesota during recent surveys for porcini mushrooms, but additional surveys are needed. Given its limited known distribution, the assignment of Special Concern status is needed and reasonable.

SPECIES STATUS SHEET

SCIENTIFIC NAME:

COMMON NAME: A Species of Cup Fungus

CURRENT MINNESOTA STATUS: None

PROPOSED MINNESOTA STATUS: Special Concern

BASIS FOR PROPOSED MINNESOTA STATUS: Sarcosoma globosum is a large distinctive species of fungus that forms a dark brown gelatinous cup. In Minnesota, it is known from only Johnson Lake, Superior National Forest, St. Louis County, where it was found fruiting in shaded, moist pine needle duff in depauperate herbaceous layer, under Betula papyrifera, Populus tremuloides, and Abies balsamea, with Pinus strobus nearby. This species of fungus fruits in the spring, and was recorded in late May in Minnesota. Members of the are likely saprobic. Sarcosoma globosum is reported in the literature as distributed from the Great Lakes region east to New England and adjacent Canada with occasional reports from Idaho, Oregon and California. It is considered rare in both North America and Europe, where the European Council for Conservation of Fungi has proposed it for listing under the Bern Convention. Although additional surveys are warranted, its single known Minnesota location indicates that the assignment of Special Concern status is needed and reasonable.
