 In the early 1990s, a team of biologists reported in the journal Nature that they had found high levels of genetic identity in samples of a species of fungus (Armillaris bulbosa), which had taken over a large geographic region in Michigan’s Upper Peninsula. They used this data to make a case for viewing these samples as constituting parts of one gigantic biological individual with an estimated biomass of more than ten tons and an estimated age exceeding 1500 years. They concluded that “members of the fungal kingdom should now be recognized as among the oldest and largest organisms on earth” (Smith, Bruhn, &amp; Anderson 1992: 431). Some scientists have questioned whether this final claim about the organismal status of the humungous fungus is warranted, and some have argued it is mistaken to say the gigantic fungus constitutes a single biological individual. Since then, other scientists have recognized even larger funguses as biological individuals (Schmitt &amp; Tatum 2008).
