Type species – Camarosporium quaternatum (Hazsl.) Schulzer.
≡ Clinterium quaternatum Hazsl., Verh. zool.-bot. Ges. Wien 15: 451 (1865).
Notes – Camarosporium quaternatum was introduced by Schulzer (1870) with a karstenula- like sexual morph and phoma-like synasexual morph (Crous & Groenewald 2017). This is the type species of Camarosporium. Schulzer (1870) did not provide illustrations for C. quaternatum but, he mentioned it has close affinity to Clinterium lycii, described by Hazslinszky (1865). Because the type material of C. quaternatum has been lost, the original illustrations are described in most recent study by Crous & Groenewald (2017) from lectotypes to facilitate epitypification (Wanasinghe et al. 2017a). Camarosporium resembles Camarographium, Camarosporiopsis, Camarosporula, Dichomera, Didymellocamarosporium, Hazslinszkyomyces, Libertasomyces, Magnicamarosporium, Melanocamarosporium, Melnikia, Murilentithecium, Neocamarosporium, Paracamarosporium, Phragmocamarosporium, Pseudocamarosporium, Pseudohendersonia, Suttonomyces and Xenocamarosporium by conidial shape and the septation. However, these taxa are phylogenetically distinct and have subtle but specific morphological differences (Crous & Groenewald 2017, Wanasinghe et al. 2017a).
