Hesperomyces halyziae

Ciri dan struktur

Morphologically very similar to other taxa within H. virescens sensu lato, but forming a distinct species supported by ITS data. The ITS sequence shares 95.8–97.9% identity with H. virescens s.l. from Harmonia axyridis, and 96.5–95.4% with H. virescens s.l. from Adalia bipunctata / A. decempunctata. Unique molecular synapomorphies in the ITS at positions 478, 517, 652. Thallus 335–453 μm long from foot to perithecial apex; colored yellow except for a somewhat darker region right above the foot. Cell I obtriangular, 2.0–2.5× longer than broad, broadening distally, with very oblique septum I–II. Cell II longer than broad, 23–28 × 16–21 µm, subtrapezoidal in section. Cell III always smaller than cell II, 14–20 × 14–19 µm, with inflated dorsal cell wall. Primary appendage consisting of 4 superposed cells, 61–67 μm long; in the same axis as cells I and III, separated from the latter by the constricted primary septum; its basal cell somewhat longer than broad, longer than each of the remaining cells of the appendage; second to fourth cells carrying a single antherium externally, the fourth cell also carrying a second upwardly directed antherium. Antheridia flask-shaped, with slightly (dorsally and/or basally) curved efferent necks, the upper antheridium carrying at its dorsal side a pointed process, which represents the original ascospore apex. Cell VI with subparallel margins to broadening distally, 33–70 × 23–33 μm. Perithecium 194–291 × 62–86 μm (not including basal cells), symmetric or with the anterior margin convex and the posterior one almost straight or concave; broadest near the upper third, then gradually tapering towards the apex; apex complex with 2 short lower lobes, 2 upper (terminal) lobes, and 2 prominent lips surrounding the ostiole; lower lobes tapering to a rounded tip, the ventral lobe outwardly directed; terminal lobes unicellular, elongated, 29–42 μm in length, curved upwards and outwardly; ostiole with two lips, 25–29 μm in length, one lip triangular, the other slightly shorter, blunt or rounded, basally carrying the remainder of the trichogyne.

Habitat dan peran ekologis

On Halyzia sedecimguttata from Belgium and the Netherlands. Previously reported as H. virescens (Haelewaters and van Wielink 2016, Haelewaters et al. 2017) and H. virescens sensu lato (De Kesel et al. 2020). One unverified record is available from France (Justamond 2019).
