Classification: Xanthopyreniaceae, Collemopsidiales, Incertae sedis, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi.

            Based on conventional macro- and microscopic techniques, van den Boom and Etayo (2014) established Zwackhiomacromyces to accommodate the type species Zwackhiomacromyces constrictocarpus. Subsequently, Berger and Zimmermann (2016) synonym Pyrenidium hyalosporum under Zwackhiomacromyces (Z. hyalosporus), based on morphological studies. Zwackhiomacromyces as lichenicolous fungi with ascomata perithecioid, black, pyriform, branched and anastomosed pseudoparaphyses, fissitunicate asci, elongate-clavate, apically thickened and with an ocular chamber, and ellipsoid ascospores, hyaline, (2–)3-septate, smooth-walled, without a subapical germpore-like spot (van den Boom & Etayo 2014). No further species have been introduced to this genus, which remains as two species in Zwackhiomacromyces. In addition, this genus still lacks DNA sequences; there is a future need to re-collect fresh specimens.
