A new species of truffle, , is described from central Mexico. can be distinguished from other related species synoptically by a combination of morphological features including ascospore size, pellis cells with irregular thickness, cystidia, ascoma colour and associated host ( an endemic species from central Mexico); sequence variation on the ITS rDNA also distinguishes from related species. A phylogenetic analysis of the ITS rDNA demonstrates that belongs to the Maculatum clade and is unique from other similar small, white-cream coloured species distributed in north-eastern Mexico such as and .
