Capnodium Mont. Annls Sci. Nat., Bot., sér. 311: 233 (1849), MycoBank: MB 809 Figs. 25 and 26
Saprobic on sugary exudates from insects growing on the surface of leaves, fruits, stems and other non plant objects. Thallus a loose or dense network of pale brown, superficial hyphae or a thick pseudoparenchymatous stroma, with sexual and asexual states often growing together. Sexual state: Ascomata superficial on mycelium of thallus, brown to dark brown or black, globose to ellipsoidal, short-stalked or sessile, ostiolate at maturity, scattered or in groups, without setae. Peridium comprising dark brown to pale brown, thick-walled cells forming a textura angularis . Hamathecium lacking pseudoparaphyses. Asci 8-spored, bitunicate, clavate, ovoid or saccate, apedicellate, lacking an ocular chamber. Ascospores overlapping bi-seriate, brown, oblong or ovoid and some reniform, transversely septate with one or more vertical septa or without vertical septa. Asexual state: “Polychaeton” spp. Pycnidia elongate, often with long stalks, dark brown. Ostiole at apex of pycnidia with hyphae continued upwards to the tapered neck, terminating in an ostiole which is surrounded by dull hyphal round ends. Conidia hyaline, 1-celled.
Notes : Chomnunti et al. (2011) revisited the sooty mould genera in Capnodiaceae based on examination of types and a RAxML maximum likelihood tree based on combined LSU and SSU genes, using 15 specimens of sooty moulds from Thailand; Phragmocapnias and Scorias were also epitypified (Chomnunti et al. 2011). In addition, it was suggested that Capnodium should be used rather than Polychaeton, because it is better known, has widespread use and is the sexual state and type of the family and order. Hawksworth (2012) gave Capnodium as the example for widely used names of fungi that could be proposed for use, against the older lesser used asexual name (Polychaeton). It is expected that Capnodium will be defined for future use in the lists of accepted names to be approved by the General Committee under Art. 14.13. The sexual state of Capnodium is illustrated here based on Capnodium tiliae Berk. & Desm., and the asexual state is illustrated based on a recent collection of Capnodium coartatum Chomnunti & K.D. Hyde,. Acanthorus Bat. & Cavalc. was reported in Abolisiaceae which is pycnidial (Batista and Cavalcante 1967) and an invalid family. Kirk et al. (2008) mention that Acanthorus is the asexual state of Capnodiaceae, but this has not been followed by other researchers.
