Elletevera

Elletevera Deighton, Mycol. Pap. 118: 17 (1969).

Index Fungorum number: IF 8140; Facesoffungi number: FoF 08603, 2 morphological species (Species Fungorum 2021), molecular data unavailable.

Hyperparasitic on host. Sexual morph: Unknown. Asexual morph: Mycelium immersed in the host fungus. Conidiophores dilute brown, smooth, branched, well developed, fasciculate, thin-walled: conidial scars conspicuous, slightly but distinctly thickened, prominent, aggregated towards the apices of the branchlets of the conidiophores. Conidia concolorous with the conidiophores, smooth, thin-walled, mostly cylindric-clavate and 3-septate, sometimes 0–2-septate, the shorter ones very rarely catenulate, sometimes fusoid, rostrate and pluriseptate, with a conspicuous and slightly but distinctly thickened hilum (Adapted from Videira et al. 2017).

 

Type species: Elletevera parasitica (Ellis & Everh.) Deighton

 

Notes: Elletevera was introduced by Deighton (1969) with E. parasitica as type species. Elletevera accommodates taxa characterized by hyperparasitic cercosporoid hyphomycetes with distinct conidiogenous loci. Braun et al. (2013) suggested that the conidiogenous loci description were wrongly reported by the original authors and the denticle like loci are rather unthickened and undarkened. Videira et al. (2017) suggested that Elletevera may be related to Pseudocercospora but cultures and sequence data are needed to confirm this hypothesis. Elletevera is currently treated as a doubtful genus in Mycosphaerellaceae.
