Lizonia
Lizonia (Ces. & De Not.) De Not., Hedwigia 4: 23 (1863) [1865].
Index Fungorum number: IF 2902; Facesoffungi number: FoF 08271, 16 morphological species (Species Fungorum 2022), 1 species with molecular data.
Parasitic, foliicolous on perichaetial leaves of living mosses. Superficial mycelium absent. Sexual morph: Ascomata superficial, solitary or grouped, globose to subglobose, with an obscure ostiole. Peridium 3–4 layers of brown cells of textura angularis. Hamathecium comprising numerous, cylindrical, unbranched, septate, cellular pseudoparaphyses. Asci 8-spored, bitunicate, cylindric-clavate, sessile or with short pedicel, rounded at apex. Ascospores 1–2-seriate, ellipsoidal to fusiform, brown, uniseptate, slightly verrucose, upper cell broader than lower cell. Asexual morph: Unknown (adapted from Boonmee et al. 2017).
Type species: Lizonia empirigonia (Auersw.) De Not.
Notes: The subgenus Cucurbitaria was raised to generic level with Lizonia empirigonia as the type species (Cesati & De Notaris 1863). Lizonia was assigned to different families by several authors (Cesati & De Notaris 1863, Hansford 1946, Arx & Müller 1975, Döbbeler 1978, Barr 1987, Eriksson & Hawksworth 1993). Lizonia is unique in having a bryophilous lifestyle and is characterised by superficial, globose to subglobose, black ascomata, lacking setae, bitunicate asci, pseudoparaphyses and septate, hyaline to colored ascospores. Boonmee et al. (2017) placed Lizonia in Lizoniaceae based on morphological study. Molecular markers available for Lizonia are ITS, LSU, SSU and RPB2.
