“…Macroconidia of Dactylonectria are cylindrical, straight to slightly curved with 1-4 septa with the apical cell or apex typically bent slightly to one side, microconidia are ellipsoidal to ovoid, aseptate to 1-septate. Salgado-Salazar et al (2016) established Cinnamomeonectria, Macronectria, and Tumenectria as segregate genera based on phylogenetic and morphological data resolving the paraphyly of Thelonectria. In 2017, Aiello et al described the monotypic genus, Pleiocarpon, which was the sister taxon to Thelonectria.…”

Black foot disease is a common and destructive root disease of grapevine caused by a multitude of cylindrocarponlike fungi in many viticultural areas of the world. This study identified 12 cylindrocarpon-like fungal species across five genera associated with black foot disease of grapevine and other diverse root diseases of fruit and nut crops in the Central Valley Region of California. Morphological observations paired with multi-locus sequence typing of four loci, internal transcribed spacer region of nuclear rDNA ITS1-5.8S-ITS2 (ITS), beta-tubulin (TUB2), translation elongation factor 1-alpha (TEF1), and histone (HIS), revealed 10 previously described species; Campylocarpon fasciculare, Dactylonectria alcacerensis,

“…Moreover, these genera morphologically resemble Thelonectria, and are mostly found on bark or exposed wood of dead, dying or diseased trees, and are rarely associated with small cankers and root rots (Chaverri et al . 2011, Salgado-Salazar et al . 2016).…”

“…Past phylogenetic studies (Chaverri et al . 2011, Salgado-Salazar et al . 2016) have shown that this atypical species belongs in the genus Thelonectria , although this species produces chlamydospores and has shorter macroconidia.…”

Pleiocarpon gen. nov. and a new species of Ilyonectria causing basal rot of Strelitzia reginae in Italy

et al. 2017

During 2015, a new basal rot disease was observed on potted plants of Strelitzia reginae in an ornamental nursery located in eastern Sicily. Isolations from symptomatic parts of these diseased plants consistently yielded cylindrocarpon-like isolates. Multigene analyses of the partial gene regions of 28S large subunit nrDNA, β-tubulin, histone H3, translation elongation factor 1-alpha, internal transcribed spacer region and intervening 5.8S nrRNA gene, and RNA polymerase II second largest subunit genes, supported by morphological characters supported the recognition of a new genus, Pleiocarpon based on P. strelitziae sp. nov., and a new Ilyonectria species, described here as I. strelitziae sp. nov. The pathogenicity of both I. strelitziae and P. strelitziae were confirmed on young plants cultivated under controlled conditions in a growth chamber. Both cylindrocarpon-like fungi were pathogenic to S. reginae and reproduced symptoms similar to those observed in the nursery. Of the two species, P. strelitziae was more aggressive than I. strelitziae, resulting in the death of all inoculated plants.

“…Thelonectria P. Chaverri & C. Salgado, typified by T.discophora (Mont.) P. Chaverri & C. Salgado, was established by Chaverri et al (2011) to accommodate the nectriaceous fungi having superficial, globose to subglobose or pyriform to elongated perithecia which do not collapse when dry, with a prominent and darkened papilla; smooth, rarely spinulose or striate ascospores and curved macroconidia with rounded ends (Chaverri et al 2011; Lombard et al 2015; Salgado-Salazar et al 2016). About 44 species are currently accepted in the genus (Chaverri et al 2011; Salgado-Salazar et al 2012, 2015, 2016; Zeng and Zhuang 2013; Crous et al 2018).…”

Species in the genera Rugonectria and Thelonectria are distributed in the tropics, subtropics and temperate regions and occur on early decaying bark, roots, branches, trunks and rarely in soil (Chaverri et al 2011; Salgado-Salazar et al 2015).…”

Recent collections and herbarium specimens of Rugonectria and Thelonectria from different regions of China were examined. Using combined analyses of morphological and molecular data, 17 species are recognised including three species of Rugonectria and 14 species in Thelonectria. Amongst them, R.microconidia and T.guangdongensis are new to science. Rugonectriamicroconidia on mossy bark is characterised by superficial, yellow to orange, pyriform to subglobose perithecia with a warted surface; ellipsoidal to broadly ellipsoidal, striate, uniseptate ascospores; and allantoid to rod-shaped, aseptate microconidia. Thelonectriaguangdongensis possesses bright red perithecia with a slightly roughened surface and a prominently dark papilla; ellipsoidal, smooth, uniseptate ascospores; and subcylindrical, slightly curved, multiseptate macroconidia. Morphological distinctions and sequence divergences between the new species and their close relatives are discussed. Name changes for the previously recorded species in China are noted.
