Geastrum pectinatum differs most obviously in lacking the basal collar, but has more elevated warts, and generally somewhat darker capillitial hyphae, (Pegler(4)).Habitat
usually gregarious; "in woods, gardens and parks, amongst litter, often on rich or calcareous soil", (Pegler for Britain), usually in small to large, trooping +/- tufted groups; on rich soil in woods, parkland, gardens, dunes, cemeteries and other habitats, most often with conifers; late summer and fall, (Buczacki for Britain/Ireland)
