 Compatibility tests as well as molecular analysis indicated that A. areolatum separated very early from other Amylostereum fungi . The other three species separated later from each other and are thus partially compatible to each other . A. ferreum and A. laevigatum produced in 59 % of all cases a common mycelium , A. ferreum and A. chailletii only in 44 % . There is an undescribed species in Amylostereum ; according to DNA analysis , it stands between A. laevigatum and A. ferreum . This is remarkable , as these fungi originated from Mycetangae ( storing organs of Platypodinae ) of a North American wood wasp , while A. laevigatum has never been seen as symbiont of wood wasps , neither in North American nor in Europe . The fungus possibly represents a separated species or a subtaxon of A. laevigatum . As A. areolatum and A. chailletii mainly reproduce asexually through the symbiosis of wood wasps , the genetic variability within these species is relatively low .
