Type species Kretzschmaria clavus (Fr.) Sacc.

Notes Kretzschmaria was established by Fries (1849) which is similar to Xylaria. The genus is characterized by pulvinate or effused-pulvinate stromata attached to the substrate by narrow connectives, or clavate, turbinate, obconical, peltate-discoid, often aggregated into a crust- like mass. Pourmoghaddam et al. (2018) provided an update for the genus while introducing two new species K. hedjaroudei and K. iranica from Iran.
