 Bryoparasitic Pezizales > Identification


The main characteristics for species identification are ascospore-size and ornamentation as well as the host species. Below, there is a tentative key, which leads to main groups of species with similar spores. Apart from the key, a list of fungi with their known bryophyte hosts and a list of host bryophytes with the associated parasitic fungi may also help with idendification.
