Type speciesApiothyrium arcticum Petr.

NotesApiothyrium was introduced to accommodate A. arcticum occurring on dead leaves of Diapensia lapponica (Diapensiaceae) in Finland and later A. tasmanicum on dead needles of Athrotaxis cupressoides (Cupressaceae) in Tasmania, Australia (Petrak 1947a, Swart 1988b). Apiothyrium species have solitary, immersed ascomata, visible as dots on the host surface, with a central ostiole, irregular stromata, cylindric-clavate asci with a J+, apical ring, and hyaline, oblong to clavate, apiospores with a mucilaginous sheath (Petrak 1947a, Swart 1988b).
