Remarks
First record from Denmark. Distinctiveness of the three species of Euphoriomyces described on beetles of the genus Agathidium (E. agathidii, E. bilateralis and E. unilateralis) was analyzed by Rossi et al. (2019a). Euphoriomyces agathidii and E. unilateralis seem to be well-separable because the latter only bears secondary appendages and perithecia on the same side of the thallus. The presence of Euphoriomyces bilateralis in Europe and its distinctiveness from E. agathidii is questionable; it was described from Sumatra (Thaxter 1931) but the later Spanish record (Santamaria 1991) probably belongs to E. agathidii.
