Basionym : Pseudoacrodictys balansae Y.R.Ma & X.G.Zhang , Nova Hedwigia, 102: 70.

Description and figures:— as Pseudoacrodictys balansae in Ma et al. (2016).

Notes:— This species was distinguished by its authors from the others species formerly placed in Pseudoacrodictys by its sub-napiform, turbinate to irregular conidial shape and curly, undulate and swollen appendages scattered toward the apex ( Ma et al. 2016). We analyzed the description and illustration given for Pa. balansae with focus mainly in the process of conidial detachment, which could be observed in Fig. 1B from original article ( Ma et al. 2016), and we conclude that the conidial secession is rhexolytic; the teared appearance of the basal conidial cell can also be observed in Fig. 1D from Ma et al. (2016).

Geographical distribution: — CHINA (as Pseudoacrodictys balansae Ma et al. 2016 )

Comparing with the type species of the genus, they both have monoblastic, indeterminate, with percurrent elongations and solitary, acrogenous, holoblastic conidia with rhexolytic secession and with inconspicuous oblique thin septa and basal cell cylindrical, delimited by a transverse, cambered septum. But Pa. balansae have more variable and bigger conidia and more numerous, aseptate, curly, swollen appendages scattered towards the apex of the conidia, and also, conidiogenous cell are cylindrical when compared with Pa. catolensis .
