Schildia sancti-luxurii is clavarioid species described in 2015 for the San Rossore Estate in Italy. So far it has not been collected in any other locations, but given its recent description it is difficult to determine whether it has a restricted distribution and small population size or if it is confused with other species in other regions. Further search efforts are needed so this species is assessed as Data Deficient (DD).

Schildia sancti-luxurii is the type species of the monotypic genus Schildia, established in 2015 based on morphological and molecular data (Franchi and Marchetti, 2015). However, Gminder et al. (2020) noted that the creation of this separate genus may not be justified, and further phylogenetic studies are needed to clarify its taxonomic position both at species and order level.

Only known from the San Rossore Estate within the Park of Migliarino San Rossore Massaciuccoli in Tuscany, Italy.

The species has so far only been documented in the San Rossore Estate. Given its recent description it is not yet clear whether it has a restricted distribution or if it has so far been confused with other species or under-sampled. Further search efforts are needed to determine population size.

Assumed to be mycorrhizal, found with Quercus ilex, Pinus pinaster and P. pinea on sandy substrate in Mediterranean forest (Franchi and Marchetti, 2015).

Since S. sancti-luxurii may have a wide range of hosts, further research into habitat and host preferences is needed to help determine threats.

Specimens were found within a protected natural park.

Search efforts outside the San Rossore Estate are needed to help estimate population size, distribution and help define host preferences. Research to confirm its taxonomic placement is also recommended.
