Ascomycota, genera incertae sedis


Saprobic on the host plant in terrestrial habitat, such as Clethra alnifolia, C. acuminata (Clethraceae). Sexual morph: putative sexual morph see Groves (1965). Asexual morph: Conidiomata dark brown, pycnidial, solitary to gregarious, semi-immersed to erumpent, cylindrical to cylindrical-subulate, sometimes bent, unilocular, locule extending the length of the beak and somewhat enlarged in the basal part, glabrous, beaked. Conidiomatal wall composed of thick-walled, hyaline to dark brown, somewhat interwoven to almost parallel hyphae of textura epidermoidea in the outer layer, becoming thick-walled, yellowish hyphae of textura oblita in the wall of the beak. Conidiophores arising from basal and lateral walls, hyaline, simple, branched, septate, smooth-walled. Conidiogenous cells hyaline, holothallic, cylindrical, determinate, smooth-walled. Conidia hyaline, arthric, formed by disarticulation of the conidial chain, produced in simple unbranched chains with the oldest conidium at the apex, cylindrical to ellipsoid, rounded at both ends or occasionally truncate at the base, unicellular, smooth-walled (Groves 1965, Morgan-Jones 1977).


Type species: Chondropodiella clethrincola (Ellis) Höhn., Hedwigia 59(5): 281 (1917)


Notes: The cylindrical to subulate conidiomata with locule extending the length of the beak and somewhat enlarged in the basal part in Chondropodiella is similar to Corniculariella. However, Corniculariella can be distinguished from Chondropodiella by its enteroblastic, phialidic conidiogenous cells and falcate or fusiform to clavate, 1–10-septate, curved conidia (Morgan-Jones et al. 1972d, this study). Chondropodiella has holothallic, cylindrical, septate conidiogenous cells, and hyaline, arthric, aseptate conidia formed by disarticulation of the unbranched conidial chain, with the oldest conidium at the apex, which can easily be confused with Phellostroma (Morgan-Jones et al. 1972d, Sutton 1980). However, the latter can be separated by its stromatic, pycnidial, cushion-shaped, multilocular conidiomata (Morgan-Jones et al. 1972d).

Chondropodiella is monotypic. Chondropodiella clethrincola was generally considered as the microconidial state of species placed in Godronia (Coolce and Ellis 1877, Groves 1965, Sutton 1977a). However, it is unclear whether Chondropodiella is congeneric with Godronia as no DNA sequence data exists for either generic type. Therefore, Chondropodiella should be treated as a legitimate name rather than reduced to a synonym of Godronia (Kirk et al. 2013). Fresh collections of this species are needed to clear up the placement of this genus and its putative sexual morph.
