<taxonomicName lsidName="S. nivea" pageId="0" pageNumber="45" rank="species" species="nivea">S. nivea</taxonomicName>

complex. Macroscopically, the only other studied specimen from Tasmania looks quite different from the type. However, we could not identify any clear microscopic differences and cannot rule out the possibility that the macroscopic differences represent variation between developmental stages. Nevertheless, considering the level of crypticity in the
|
||
<taxonomicName lsidName="S. nivea" pageId="0" pageNumber="45" rank="species" species="nivea">S. nivea</taxonomicName>
|
||
