Dothiorella californica D.P. Lawr. & Trouillas 2017
Index Fungorum number: IF 817293; Facesoffungi number: FoF 14005
Saprobic on a dead aerial branch of Laurus nobilis L. Sexual morph: Ascomata 300–350 μm diam., 300–370 μm high (x̄ = 320 × 340 μm, n = 5), pseudothecial, globose to subglobose, semi-immersed, scattered or aggregated, erumpent at maturity, ostiolate, black. Ostioles 80–90 μm high, circular, papillate, central, single. Peridium 40–55 μm thick, composed multi-layered, from outer to inside walls composed of dark brown to pale brown cells of textura angularis to textura globulosa. Hamathecium comprises 2–3 μm wide, thin-walled, hyaline, septate, numerous pseudoparaphyses. Asci 70–135 × 17–22 μm (x̄ = 95 × 18 μm, n = 10), stipitate, arising from the base of the ascoma, cylindric-clavate, bitunicate, with a well-developed apical chamber, 8-spored, uniseriate to biseriate. Ascospores 15–30 × 7–15 μm (x̄ = 21 × 10 μm, n = 20; l/w = 2.1), elliptical to ovate, widest in the middle part, initially aseptate, 1-septate at maturity, slightly constricted at the septum, moderately thick-walled, finely verruculose on the inner surface, initially hyaline, becoming dark brown at maturity. Asexual morph: see Lawrence et al. (2017).
