Lycoperdon echinatum is a Eurasian species (Demoulin 1972, Jeppson 2018). Numerous record of it from North America belong to a closely related, vicariant species, L. americanum. Yet another American species is often mistaken for L. echinatum: L. pulcherrimum.

Lycoperdon echinatum is a Eurasian species of nemoral or montane deciduous woodlands. Modern forestry is a potential threat but the population seems to be fairly stable. LC? NT?

Lycoperdon echinatum is a Eurasian species, widespread and fairly abundant in Central and western Europe. American records (GBIF, iNaturalist) refer to L. americanum or other species (L. pulcherrimum, L. marginatum and other species with spiny exoperidium) Records from Australia and Africa need to be verified.

Lycoperdon echinatum seems to have a fairly stable population in Europe. It is widely distributed and common in suitable habitats throughout Europe and Asian part of Russia. Records from the Americas and Australia appear to belong to other species.

Lycoperdon echinatum is a thermophilous species of nemoral or montane woodlands (Carpinus, Quercus, Fagus, Corylus etc).

Modern forestry is a threat to this species, however population seems to be fairly stable.

Research is need to clarify the morphological and molecular charactersitics of the American L. americanum versus those of L. echinatum of Eurasia.
