Camarosporioides W.J. Li & K.D. Hyde, in Hyde et al., Fungal Diversity 80: 83 (2016).

Index Fungorum number: IF 552209; Facesoffungi number: FoF 02350, 1 morphological species (Species Fungorum 2022), 1 species with molecular data

Saprobic on dead stems of Poaceae. Sexual morph: Unknown. Asexual morph: Conidiomata yellowish to brown, separate or aggregated, pycnidial, obpyriform, immersed, unilocular, thick-walled, smooth, ostiolate. Ostiole single, circular, with hyaline periphyses, centrally located, papillate. Periphyses hyaline, hyphae-like, smooth, subcylindrical, with obtuse apex, unbranched, septate. Conidiomatal wall composed of thick-walled, brown cells of textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells hyaline to pale brown, holoblastic, long lageniform, swollen at the base, discrete, determinate, formed from the cells lining the inner wall of the conidioma. Conidia pale brown to brown, finely roughened, ellipsoidal to oval, obtuse at the apex, slightly truncate at base, with primary transverse septa, with a longitudinal septum, constricted at septa, verruculose, thick-walled (adapted from Hyde et al. 2016).


Type species: Camarosporioides phragmitis W.J. Li & K.D. Hyde


Notes: Camarosporioides shares similar conidial morphology with Phragmocamarosporium (Massarinaceae), but Phragmocamarosporium lacks periphyses. Camarosporioides is unique in having yellowish to brown, obpyriform, immersed conidiomata. Molecular markers available for Camarosporioides include ITS, LSU, SSU, and TEF-1.
