Annellosympodiella
Annellosympodiella Crous & Assefa, in Crous et al., Persoonia 32: 245 (2014).
Index Fungorum number: IF 808928; Facesoffungi number: FoF 08473, 1 morphological species (Species Fungorum 2022), 1 species with molecular data.
Saprobic or pathogenic on host. Sexual morph: Unknown. Asexual morph: Conidiomata sporodochial on leaflets, arising from an erumpent brown stroma, consisting of brown, subcylindrical cells. Conidiophores densely aggregated, subcylindrical, brown, verruculose to warty, rejuvenating percurrently, septate. Conidiogenous cells integrated, terminal, brown, verruculose, proliferating percurrently with irregular annellations, and long, brown, tubular collarettes. Sympodial scars are also visible on the tubular collarette, circular, thickened, darkened and refractive, suggestive of sympodial proliferation. Conidia solitary, brown, verruculose to warty, guttulate, subcylindrical to narrowly obclavate, straight to curved, euseptate; hilum truncate, thickened and slightly darkened (adapted from Crous et al. 2014).
Type species: Annellosympodiella juniperi Crous & Assefa
Notes: Annellosympodiella is characterised by sporodochial conidiomata, integrated, terminal, brown conidiogeneous cells, circular, thickened, darkened sympodial scars and solitary, brown, verruculose to warty conidia. Annellosympodiella resembles Annellophragmia in having percurrent and sympodial proliferation with darkened and thickened scars but the latter has superficial fascicles, lacks sporodochia, has a stroma, long protuberant collarettes, and 0–1-septate conidia. Annellosympodiella can be distinguished from similar genera based on DNA sequence data. Annellosympodiella is a distinct and well-supported genus in Mycosphaerellaceae. Molecular markers available for Annellosympodiella are ITS, LSU and RPB2.
