Kabatina R. Schneid. & Arx, Phytopath. Z. 57: 179 (1966).
Type species: Kabatina thujae R. Schneid. & Arx, Phytopath. Z. 57: 180 (1966)
Parasitic on branches of Abies, Juniperus, Mahonia, Populus and Thuja. Sexual state: Unknown. Asexual state: Mycelium immersed, branched, septate, hyaline to pale brown or black. Conidiomata dark brown to black, sporodochial or acervular, epidermal to subepidermal, pulvinate, pale to dark brown, partially immersed inside the host, composed of branched, septate hyphae, amphigenous or hypophyllous, thick-walled textura angularis. Dehiscence by irregular rupture of the cuticle and epidermis. Conidiophores stromatic or branched, clustered together resembling a synnema, septate, hyaline to pale brown, smooth. Conidiogenous cells enteroblastic, phialidic or percurrent, determinate, cylindrical to doliiform or subclavate, brown to pale brown, channel and collarette minute, periclinal thickening present or absent, borne terminally and intercalary. Conidia hyaline, aseptate, cylindrical to ellipsoid, terminal in basipetal chains or singly, conidial secession schizolytic, smooth (Sutton 1980; Butin and Pehl 1993; Seifert et al. 2011).
Notes: Kabatina was introduced by Schneider and Arx (1966) to accommodate K. juniperi R. Schneid. & Arx, and K. thujae R. Schneid. & Arx,. Butin and Schneider (1976), Ramaley (1992) and Butin and Pehl (1993) added K. populi Butin & R. Schneid., K. mahoniae A.W. Ramaley and K. abietis Butin & Pehl, respectively. This genus was shown to group as a sister clade with Dothidea hippophaës and D. insculpta Wallr. by Tsuneda et al. (2004). Bills et al. (2004) also showed that the phylogenetic placement of K. thujae and K. juniperi (CBS 239.66, CBS 466.66) in Dothideales with Hormonea species based on the phylogenetic analysis of ITS1-5.8S-ITS2 rDNA (ITS) data. Wijayawardene et al. (2012) placed this genus under Dothioraceae, while Hyde et al. (2013) categorized Kabatina as an asexual genus in the family Dothideaceae. We also accept Kabatina as an asexual genus in Dothideaceae considering above facts. Although, Kabatina presently comprises nine epithets (Index Fungorum 2014), only ITS sequence data are available in GenBank therefore, we did not include the Kabatina species in to our phylogenetic tree. Species of Kabatina need to be sequenced for protein-coding genes and nuclear ribosomal genes in order to obtain a better resolution.
Kabatina species cause several desease known as “Evergreen Disease, Needle Cast of Firs” and economic losses in Abies, Juniperus, Mahonia and Populus and is associated with needle diebacks in conifers (Sutton 1980; Tisserat et al. 1997; Bills et al. 2004; Cech et al. 2009).
