Conidiophores arising laterally or terminally from somatic hyphae, 20.2–74.7 μm long, unbranched or branched, hyaline, smooth- and thin-walled, bearing terminal and lateral conidiogenous cells, or reduced to single conidiogenous cells borne laterally or terminally on aerial hyphae. Conidiogenous cells monophialidic, subulate or subcylindrical, hyaline, smooth- and thin-walled, 20.2–55.4 μm long, at the base 2.0–3.3 μm wide and at the apex 1.2–1.9 μm wide, without noticeable periclinal thickening, collarettes absent or sometimes a minute apical collarette can be present.

C. elegans has more elongated conidia in shape (mostly ellipsoidal and cylindrical) and larger in size (3.5–14.7 μm) in contrast to C. viridescens whose conidia are globose or reniform and reaching 4–8 μm long (Booth 1959). Additionally, C. elegans has smaller conidiophores which reach 74.7 μm in length in the type specimen whereas conidiophores of C. viridescens reach 500 μm (Booth 1959). Moreover, C. elegans rarely forms single chlamydospores in contrast to C. viridescens in which chlamydospores are absent (Booth 1959).</p></div>	https://treatment.plazi.org/id/1C81298FFFDF5945AEF21CDC09641FEC	Public Domain	No known copyright restrictions apply.

All these genera formed the highly supported clade (MLB = 99 %, BPP = 1) but with unresolved relationship between genera in this group (Fig. 2). Pulchrospora resinae produces micro- and macroconidia similarly to Dialonectria and Cosmosporella . However, P. resinae produces microconidia on aerial conidiophores and macroconidia are produced on sporodochial conidiophores, like in the genus Dialonectria, but differently from the genus Cosmosporella whose members produce micro- and macroconidia on aerial conidiophores (Huang et al. 2018; Crous et al. 2021; Perera et al. 2023). Moreover, the general morphology of macroconidia between these genera differs significantly. Macroconidia of P. resinae are characterised by being regularly wide along almost the entire length, tapering toward the apex (mostly) and obtuse, non-foot-shaped base, in contrast to members of Dialonectria and Cosmosporella, whose macroconidia are characterised by slightly tapering towards both ends and having foot-shaped basal cells (Crous et al. 2021). Additionally, macroconidia of Cosmosporella are commonly irregularly wide and longer (50–90 μm) than macroconidia of P. resinae which measured 14.3–44.8 μm (Gerlach and Nirenberg 1982; Crous et al. 2021).</p></div>	https://treatment.plazi.org/id/71F33282AE2F57DFB77E6C5B8021920A	Public Domain	No known copyright restrictions apply.
