Anariste

Anariste Syd., Annls mycol. 25(1/2): 76 (1927).

Index Fungorum number: IF 143; Facesoffungi number: FoF 05148, 1 morphological species (Species Fungorum 2022), no molecular data available.

Epiphytes on the upper surface of the leaves. Sexual morph: Thyriothecia solitary, scattered, superficial, easily removed from the host surface, circular, dark brown to black, with ostiole at the centre of the thyriothecium and with bright brown margin. Upper wall composed of interwoven cells, basal wall poorly developed. Hamathecium of hyaline pseudoparaphyses, arranged longitudinally in the thyriothecium. Asci 8-spored, cylindric-clavate, fusiform or obclavate, with a knob-like pedicel up to 7 μm, apically rounded with an indistinct ocular chamber. Ascospores overlapping 2–3 -seriate, hyaline,uniseptate, weakly constricted at the thin septum, upper cell globose to oval, lower cell conical tapering to the rounded base, smooth-walled. Asexual morph: Unknown (adapted from Hongsanan et al. 2014).

            Type species: Anariste poliothea Syd.

Notes: Anariste is characterised by solitary, scattered, superficial thyriothecia, cylindric-clavate, fusiform asci and hyaline,uniseptate ascospores weakly constricted at the thin septum. Sydow (1927) referred Anariste to Microthyriacearum. Arx and Müller (1975) and Hosagoudar (2001) placed Anariste in Asterinaceae. Anariste resembles members of Micropeltidaceae in having ostioles at the centre of the thyriothecia, upper wall comprising interwoven cells longitudinally arranged asci and cylindrical asci with pedicels. Anariste differs from other species of Micropeltidaceae in its uncommon ascospores. Hongsanan et al. (2014) re-examined the syntype of A. poliothea (BPI 690985) and excluded Anariste from the Asterinaceae and referred it to Micropeltidaceae based on its unusual ascospores. Zeng et al. (2020) transferred Anariste to Capnodiales genus incertae sedis based on its brown upper walls which differ from genera in Micropeltidaceae which have hyaline hyphae and greenish upper walls. Anariste is currently in Capnodiales genera incertae sedis. Fresh collections with DNA sequence data are needed to confirm taxonomic placement of the genus.
