 The combined characters of Archaeomarasmius indicate a relation to the modern family Tricholomataceae , with a close similarity to the genera Marasmius and Marasmiellus . Both genera are noted for <unk> , toughening and drying , rather than <unk> . This property would increase the chances of a mushroom becoming entombed in amber . However , a number of other species are also possible close relatives of Archaeomarasmius , mostly in Tricholomataceae , although some species in the family Strophariaceae are also <unk> . The authors suggest it may also be appropriate to classify Archaeomarasmius more conservatively as incertae sedis ( of uncertain placement ) within the <unk> , Agaricales , or <unk> .
