Abstract:
Genus Calvatia has been established by Fries (1849) by describing C. cyathiformis as a type species. It is characterized by medium to large sized basidioma with a reduced or well-defined sterile base. Dehiscence occurs by irregular rupturing of peridium, and not through a definite pore. Species of this genus are distributed world-wide, reported from Asia, Africa, Australia, Europe, North America and South America. Total number of the Calvatia species reported to be forty (40) so far. Many species of this genus are of wide importance with reference to its edibility and its biotechnological potential. Genus Calvatia in Pakistan is represented by five species, i.e., C. ahmadiana, C. ahmadii. C. craniiformis, C. cyathiformis, and C. excipuliformis var.excipuliformis. In this investigation, four Calvatia species have been collected from different regions of the country and described here on morphological, molecular and phylogenetic basis. These are C. cyathiformisvar. fragilis nom. prov., C. deosaiensis nom. prov., C. lilacina, and C. pseudocyathiformis nom. prov.Among these, two taxa are presented here as new species. One taxon is proposedas a new variety of C. cyathiformis. One taxon, C. lilacina is a new record for Pakistan.
