Description.

Saprobic on the branches of Prunus serrulata . Sexual morph: Ascomata 186–292 µm high, 179–267 µm diam., solitary, scattered to gregarious, immersed or erumpent, uniloculate with an ostiole. Peridium 15–30 µm, comprising several layers of cells of textura angularis, with dark brown outer layers and hyaline inner layers. Hamathecium of dense, 1–2 μm wide, filamentous, branched, septate, smooth-walled, cellular pseudoparaphyses, anastomosing at the apex, embedded in a hyaline, gelatinous matrix. Asci 53–66 × 6–8 µm (x ̄ = 61 × 7 µm, n = 20), 8 - spored, bitunicate, fissitunicate, broadly cylindrical to cylindrical-clavate, with a short pedicel, apically rounded. Ascospores 8–17 × 3–4 µm (x ̄ = 13 × 4 µm, n = 30), overlapping, hyaline, fusiform, broader at the top and narrower at the bottom, with a septum in the middle that is deeply constricted, translucent to light brown or brown, rough. Asexual morph: Undetermined.

Culture characteristics.

Ascospores germinating on PDA within 12 h. Colonies on PDA slow-growing, 9 mm diam. after 10 d at 25 ° C in the dark, circular, irregular edges, with dense grayish white mycelium on the surface, in reverse brown to black.

Material examined.

China • Guizhou Province, Xingyi City . On dead stem of Prunus serrulata , 10 July 2018, Yao Feng, nky 141 ( GZAAS 21-0243 ), living culture GZCC 21-0757 .

Notes.

The morphology and phylogenetic results confirm that our new collections are identical to Corylicola italica . The genus Corylicola was established by Wijesinghe et al. (2020) with C. italica as the type species. This species was originally described from a hanging branch of Corylus avellana in Italy ( Wijesinghe et al. 2020). This study represents the first record of C. italica in China.
