Micularia

Micularia Boedijn, Persoonia 2(1): 67 (1961).

 Index Fungorum number: IF 3207; Facesoffungi number: FoF 06550, 2 morphological species (Species Fungorum 2022), no molecular data available.

Parasitic on the upper surface of leaves forming darkened areas. Sexual morph: Ascostromata superficial, scattered, solitary or gregarious, coriaceous, semi-immersed, dark brown to black, globose to sub-globose, multi-loculate, locules scattered throughout the ascostromata, containing a single ascus in each locule, ostiolate. Ostioles minute, with dark brown hairs around apex. Paraphyses absent. Cells of ascostromata comprising dark brown cells of textura angularis. Asci 8-spored, bitunicate, fissitunicate, sub-globose to pyriform, short pedicellate, apically rounded with small ocular chamber. Ascospores hyaline, oblong to ellipsoid, 1-transverse septum, longitudinal septa absent, constricted at the septum, smooth-walled to verruculose, lacking a sheath. Asexual morph: Unknown (adapted from Dissanayake et al. 2014).

Type species: Micularia merremiae Boedijn

Notes: Micularia is characterised by having bundles of small spreading hairs at the apex of the ostiole (Boedijn 1961). Boedijn (1961) placed Micularia in family Saccardiaceae, while Lumbsch and Huhndorf (2007, 2010) placed Micularia in Elsinoaceae. This placement was followed by Hyde et al. (2013). Dissanayake et al. (2014) placed Micularia in Myriangiaceae based on the parasitic lifestyle and morphology mainly having one ascus in each locule.
