Index Fungorum, Facesoffungi, MycoBank, GenBank

Classification: Helotiales, Leotiomycetidae, Leotiomycetes, Pezizomycotina, Ascomycota, Fungi

Ecology/substrate/host: Saprobe on dead plant materials.

Geographical distribution: Widely distributed.

Description and illustration: Korf (1952); Ekanayaka et al. (2019).

Accepted chalara-like genus: Leochalara.

Notes: The family Arachnopezizeae (Helotiales) is characterized by apothecia covered by hairs; ectal excipulum textura angularis to prismatica cells, medullary excipulum textura prismatica to textura oblita cells; hyaline and cylindrical paraphyses; 8-spored, cylindric-clavate, amyloid asci arising from croziers, and ellipsoid to fusoid, 0–7-septate ascospores (Ekanayaka et al. 2019). Five genera (Arachnopeziza, Arachnoscypha, Austropezia, Eriopezia and Durella) were included in the family (Korf 1952; Ekanayaka et al. 2019; Johnston et al. 2019; Kosonen et al. 2021). None of them were reported with chalara-like anamorph. One specimen collected in China had a hyaline chalara-like fungus with hyaline conidiophores, and cylindrical, hyaline and aseptate conidia. The phylogenetic analyses showed it represented a new genus of Arachnopezizeae (Wenping and Yongzhao 2023), and Leochalara is established for it.

 

Type genus: Arachnopeziza Fuckel, Jb. nassau. Ver. Naturk. 23-24: 303 (1870)

Other accepted species: Species Fungorum – search Arachnopezizeae.
