Classification: Micropeltidaceae, Microthyriales, Incertae sedis, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi

Epiphytic on living leaves appearing as black dots. Superficial hyphae hyaline, hard to detect. Sexual morph: Thyriothecia superficial, solitary, gregarious, subdense, black, flattened, circular, dimidiate, with a circular central ostiole. Upper wall blackish green, membranous, comprising overlapping, compact, pseudoparenchymatous hyphae with textura intricata, lacking a basal plate. Hamathecium comprising of filiform, hyaline, branched paraphyses. Asci 8-spored, long ovate. Ascospores overlapping, 2-seriate, cylindrical, hyaline, more than 6 septa, constricted at septa, upper cell longer and larger than lower cells. Asexual morph: Undetermined.

Notes: Stevens & Manter (1925) introduced Scolecopeltidium in Microthyriaceae and later Wu and Hyde (2013), typified Scolecopeltidium by ascospores with more than 5-septa. However, the examined species of Wu et al. (2011a) and Wu and Hyde (2013) both have more than 15-septa (Zeng et al. 2019). Scolecopeltidium have the largest size ascospores with more septa comparing other genera in Micropeltidaceae (Wu et al. 2011a). Zeng et al. (2019) provided sequence data for S. menglaense and S. wangtianshuiense and confirmed the placement in Micropeltidaceae.

Type species: Scolecopeltidium salacensis (Racib.) F. Stevens & Manter, Bot. Gaz. 79(3): 282 (1925)

Other accepted species: Species Fungorum – search Scolecopeltidium.
