Classification: Pleosporales, Pleosporomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on bark of dead and living Tectona grandis. Asexual morph: Colonies on natural

substrate, punctiform, sporodochial, superficial, gregarious, scattered, numerous, black. Hyphae sometimes superficial and sometimes immersed, pale brown to brown, septate, slightly constricted at the septa. Conidiophores wide, micronematous, erect to slightly curved, constricted at the septa, arising from hyphae. Conidiogenous cells blastic, integrated, terminal, determinate. Conidia dictyosporous to bulbil-like, very variable in size and shape; globose to ellipsoidal to irregular, with a protruding basal cell; truncate at the base, initially pale brown, becoming brown to dark brown, muriform, horizontal on conidiogenous cell. Sexual morph: Undetermined.

Notes: Pseudocoleodictyosporaceae was established by Doilom et al. (2017) to accommodate two genera, Pseudocoleodictyospora and Subglobosporium. In combined multi-gene phylogenetic analysis with LSU, rpb-2 and SSU, Pseudocoleodictyosporaceae constituted a well supported clade adjacent to Roussoellaceae and Torulaceae (Doilom et al. 2017). The species in Pseudocoleodictyosporaceae were distinct from its sister clades, supporting its establishment as a new family. All the species from this family are recorded as saprobes on the bark of living or dead teak (Doilom et al. 2017).

Type species: Pseudocoleodictyospora Doilom & K.D. Hyde.
