Camarographium
Camarographium Bubák, Ber. dt. bot. Ges. 34: 306 (1916).
Index Fungorum number: IF 9919; Facesoffungi number: FoF 06671, 5 morphological species (Species Fungorum 2022), 2 species with molecular data.
Saprobic on twigs, branches and stems of Clematis vitalba. Sexual morph: Undetermined. Asexual morph: Conidiomata pycnidial, gregarious, immersed, globose, unilocular, dark brown, ostiolate. Ostiole papillate, single, central, circular. Conidiomata wall outer layer composed of thin-walled, brown cells of textura angularis, inner layer thin, composed of subhyaline-walled cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells enteroblastic, phialidic, determinate, discrete, hyaline, smooth. Conidia pale brown, oblong to ellipsoid, globose, base obtuse, guttulate when immature, distoseptate, with 2–4 transverse septa, numerous longitudinal or oblique septa, thin and smooth-walled, guttulate when immature (Adapted from Wijayawardene et al. 2014).
Type species: Camarographium stephensii (Berk. & Broome) Bubák
Notes: Camarographium was introduced by Bubák (1916) with C. stephensii as type species. Camarographium is characterized by pycnidial, gregarious, immersed, globose ascomata, enteroblastic, phialidic conidiogenous cells, pale brown, oblong to ellipsoid, globose, distoseptate, with 2–4 transverse septa, numerous longitudinal or oblique septa conidia. Camarographium differs from other camarosporium-like taxa in having distoseptate conidia. Wijayawardene et al. (2014) added Camarographium clematidis collected on branch of Clematis vitalba L. (Ranunculaceae) in Italy. Camarographium resembles Magnicamarosporium but differs in lacking paraphyses (Wijayawardene et al. 2014; Tanaka et al. 2015). Camarographium is currently placed in Pleosporales genera incertae sedis. Molecular markers available for Camarographium include ITS, LSU, RPB2, TEF-1 and BTUB.
