This genus was overviewed by Boehm et al. (2009a, b) and is very similar to Glonium. Both Psiloglonium and Glonium possess hyaline to yellow didymospores, somewhat constricted at the septum, with obtuse or acuminate ends, typically with cells unequal in size, borne in hysterothecia (Boehm et al. 2009a). However, phylogenetically they are distinct and introduced as two genera by Boehm et al. (2009a, b).

Type species: Psiloglonium lineare (Fr.) Petr., Ann. mycol. 21(3/4): 227 (1923). 

≡ Hysterium lineare Fr., Syst. mycol. (Lundae) 2(2): 583 (1823). 

= Glonium lineare (Fr.) De Not., G. bot. ital. 2(2): 27 (1847).

Other accepted species: Species Fungorum – search Psiloglonium.
