Originally described as Capnodium paracoartatum Q. Tian, W.J. Li & K.D. Hyde , in Li & Hyde, Fungal Diversity 100: 372 (2020) in Li et al. (2020), Nom. inval., Art. F.5.1 (Shenzhen).

Notes: Capnodium paracoartatum was first introduced by Li et al. (2020). However, it was shown as invalid due to the absence of a required identifier citation, as per ‘Nom. inval., Art. F.5.1 Shenzhen’ ( Index Fungorum (2023). This species was reported as saprobic on sugary exudates from insects and produced a thallus on the leaf surface. This thallus comprises brown to pale brown, sub-cylindrical, irregularly branched, septate, and constricted at the septa mycelium. The sexual morph of this species is similar to Ca. coartatum and the asexual morph of Ca. paracoartatum differs from Ca. coartatum by its conidial size. Li et al. (2020) mentioned that using conidial size alone is insufficient to distinguish Capnodium species. However, based on phylogenetic analyses, it has been determined that Ca. paracoartatum is a distinct species ( Li et al. 2020, FIGURE 1 in this study). Consequently, we hereby validly establish Ca. paracoartatum as a recognized species.

FIGURE 1 Phylogram of the best-scoring ML consensus tree based on a combined dataset (LSU, ITS, tef-1α and rpb2) of Capnodiaceae. Sequences obtained in this study are indicated in red, and newly established species are indicated in yellow. Isolates from type materials are in bold. The ML ultrafast bootstrap and Bayesian PP values equal to or greater than 60% and 0.90 are shown at the nodes. The tree is rooted with Scorias leucadendri (CBS 131318) and S. spongiosa (CBS 325.33).
