 The basidiospores recovered with the fruiting body were examined during the SEM study . The spores showed considerable damage from both the fossilization process and the subsequent weathering and specimen collection . They also displayed distinct halos in the amber , possibly from gas or liquid leaching out , or a reaction in the spores that prevented the resin from turning to amber . Even so , enough remained to make some observations about spore morphology . The basidiospores are broadly elliptic to oval , measuring approximately 7 @.@ 3 by 4 @.@ 7 μm , and each shows a distinct hilar appendage .
