Assessment Notes

Taxonomic notes

Tulostoma exasperatum is pantropical while var. ridleyi is endemic to South East Asia.
According to Wright (1987), Tulostoma exasperatum var. ridleyi (Massee) J.E. Wright has different features from the norm: the stems are longer, reaching more than 120 mm in length, and the basidoma is more robust. The spores are also larger 4.7-5.1 x 6.4-8.1 microns. This variety is supposedly restricted to S.E. Asia. Further study may be needed to determine if this is true.
