Classification: Elsinoaceae, Myriangiales, Dothideomycetidae, Dothideomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic and epiphytic of leaves. Sexual morph: Ascomata superficial, embedded in darkened mycelium, globose to subglobose, blackened, with periphysate ostioles. Peridium comprising two cell types, externally comprising pigmented, dark brown, thick-walled cells, with inner layer thinner and composed of hyaline, thin-walled cells. Hamathecium lacking paraphyses. Asci 8-spored, bitunicate, broadly ellipsoidal, obovate to saccate, pedicellate, with an ocular chamber. Ascospores cylindrical, hyaline, 5-septate, strongly constricted at each septum, smooth-walled, with a narrow mucilage sheath. Asexual morph: Undetermined (Tian et al. 2021).
Notes: Stevens (1925) introduced Beelia typifying B. philippinensis (Batista and Costa 1959). It was initially placed in Microthyriaceae by Stevens (1925) and validated by Petrak (1953). Later, Beelia was transferred to Myriangiaceae and Elsinoaceae and Chaetothyriaceae based on morphology. Li et al. (2011) and Hyde et al. (2013) suggested to transfer Beelia to Chaetothyriaceae based on its epiphytic habit on leaf surfaces. Tian et al. (2021) accepted this genus in Chaetothyriaceae based on its distoseptate ascospores and periphysate ostioles. Beelia is similar to Phaeosaccardinula by globose to subglobose glabrous ascomata embedded in superficial mycelia and cylindrical, hyaline ascospores. However, Beelia has 5-septate ascospores and periphysate ostiole while Phaeosaccardinula has muriform ascospores and lacking periphysate ostiole.
