Tubakia species may form different types of asexual morphs. Pycnothyria with typical scutella are a distinct character of this genus. In addition, sporodochial conidiomata are formed with clusters of conidiogenous cells e.g. on leaf veins as in T. iowensis. Crustose or pustulate pycnidioid conidiomata are formed in several Tubakia species, including T. californica, T. dryina, and T. iowensis. Holdenrieder & Kowalski (1989) introduced these conidiomata as “pycnidial” even though they lacked ostioles with conidiomata dehiscing by irregular rupture. Harrington et al. (2012) described them as “conidioma” and wrote “pycnothyrium” in brackets. These conidiomata cannot be described as pycnidia as they lack ostioles. Rather, with stromatic wall layers and a dehiscence by irregular fissures, these should rather be classified as stromatic (Braun et al. 2018).

Type species: Tubakia japonica (Sacc.) B. Sutton.

Other accepted species: Species Fungorum – search Tubakia.
