Type species – Crassimassarina macrospora A. Hashim. & Kaz. Tanaka., Persoonia 39: 61 (2017).
Notes – Crassimassarina macrospora was identified as a saprobe on dead twigs of woody plants. Lack of slit-like ostiole in ascomata, ascomatal peridium composed of carbonaceous, thick walled, black cells and multi-septate, large conidia are key morphological characters in distinguishing Crassimassarina from other genera in Lophiotremataceae.
