Index Fungorum, Facesoffungi, MycoBank, GenBank

Classification: Xylariales, Xylariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi

Saprobic on dead twigs and leaves of various hosts. Sexual morph: Ascomata superficial, solitary, black, and easily removed from the substrate, covered with dark brown, setae-like, brown hairs, comprising agglutinated mycelial strands, with a stellate arrangement, arising from cells at the perithecial surface. Ostioles pore-like opening, central, with periphyses. Peridium outer region comprising pigmented, brown cells of textura angularis, inner region comprising hyaline, flattened cells. Paraphyses numerous, hypha-like, septate, flexuose, slightly tapered towards the apex. Asci 8-spored, unitunicate, narrowly clavate, short pedicellate or apedicellate, apex rounded, with a J+, subapical ring. Ascospores biseriate, hyaline, allantoid, unicellular, smooth-walled, lacking sheaths or appendages. Asexual morph: ceratosporium-like conidia have been observed on the surface of perithecia, but may not be related.

Notes – Iodosphaeriaceae was introduced to accommodate Iodosphaeria and placed in Amphisphaeriales (Hilber & Hilber 2002). Maharachchikumbura et al. (2016b) and Samarakoon et al. (2016) placed this family within Xylariales. Iodosphaeriaceae was placed in Xylariomycetidae, families incertae sedis (Hyde et al. 2017b, Hongsanan et al. 2017, Wijayawardene et al. 2018a). We accept Iodosphaeriaceae in Amphisphaeriales based on multigene analysis of combined LSU, ITS, rpb2 and tub2 sequence data.

Type species: Iodosphaeria Samuels, E. Müll. & Petrini, Mycotaxon 28(2): 486 (1987)
