Myriostoma coliformis ([With.] ex Pers.) Corda syn. M. coliforme Geastrum coliformis With. ex Pers. Vielstieliger Erdstern Szitaszájú csillaggomba (pöfeteg) Pepper Pot. Fruit body 2–10cm across, globose, outer wall covered in a brown fleshy layer which soon wears off to show pale buff under-layer, splitting into 5–12 pointed rays which curve back slightly raising the spore sac. Spore sac 1.5–5cm across, silvery-brown and minutely roughened, opening by several pores to resemble a pepper-pot, supported by several slender columns. Spores brown, globose, irregularly warted, 4–6um in diameter. Habitat in sandy soil in fields or wood edges. Season late summer to autumn. Apparently extinct in Britain, the large specimen shown is from a collection made near Hillingdon in Norfolk, UK, Distribution, America and Europe.in 1880. Not edible. Found In Europe.
It is hoped that the publication of an illustration of this interesting fungus will lead to its rediscovery.

John Law (United Kingdom) - 20 October 2013

Specimen found March 2006 suffolk UK Dear John Many thanks for forwarding the Myriostoma specimen (which arrived today) - and congratulations on a remarkable find! As Shelley has probably said, the species was originally described from East Anglia (by Withering in 1776), but has not been seen there, or anywhere else in England, since 1880 though it is still known in Jersey. It is not so rare in southern Europe. Your specimen is rather weatherbeaten and has presumably over- wintered (having appeared in the autumn), but is still quite recognizable. We'll keep the specimen here in the national herbarium. Best regards..............Peter Roberts
