Index Fungorum number: IF 554393; Facesofungi number: FoF 04023
Etymology: The specific epithet reflects the host genus Lonicera.
Holotype: MFLU 15-2522.
Saprobic or pathogenic on stems of Lonicera sp. Sexual morph: Ascomata 250–350 μm high 180–250 μm diam. (x̄ = 299.9 × 205.1 μm, n = 5) immersed to erumpent, solitary, scattered, globose or subglobose, dark brown to black, coriaceous, ostiolate. Ostiole up to 60–80 μm long and 50–70 μm wide, papillate, blackish brown, smooth, comprising brown cells. Peridium 15–20 μm wide at the base, 20–50 μm wide at the sides, comprising heavily pigmented, thin-walled, brown to dark brown cells of textura angularis. Hamathecium comprising numerous, 1.5–2.5 μm wide, filamentous, branched, septate, pseudoparaphyses. Asci 105–120 × 9.5–12.5 μm (x̄ = 113 × 10.7 μm, n = 30), 8-spored, bitunicate, fissitunicate, cylindrical to cylindricclavate, pedicellate, thick-walled at the apex, with minute ocular chamber. Ascospores 14–17 × 7–8 μm (x̄ = 15.4 × 7.5 μm, n = 50), overlapping uniseriate, ellipsoidal, muriform, upper part wider than the lower part, 3-transversely septate, with 1 vertical septum, constricted at the central septum, initially hyaline, becoming yellowish-brown at maturity, ends remaining lighter and cone-shaped, with rounded ends. Asexual morph: Undetermined.
Material examined: ITALY, Arezzo Province, near Pieve Santo Stefano, on living branch of Lonicera sp. (Caprifoliaceae), 2 May 2014, Erio Camporesi IT 1849 (MFLU 15-2522, holotype); ex-type living culture, MFLUCC 14-0955.

Notes: Hawksworthiana lonicerae is introduced based on its sexual morph as the third species in Hawksworthiana. This morphologically fits within the generic concepts of Hawksworthiana and closely resembles the type species, H. alliariae in having globose to subglobose ascomata, cylindrical to cylindric-clavate asci and ellipsoidal, muriform ascospores (Wanasinghe et al. 2018). Currently a nomenclatural change was applied to Hawksworthiana lonicerae as Dlhawksworthia lonicerae.
