Licopolia
Licopolia Sacc., Syd. & P. Syd., in Sydow & Sydow, Bull. Herb. Boissier, 2 sér. 1: 79 (1901).
Index Fungorum number: IF 2862; Facesoffungi number: FoF 03404, 2 morphological species (Species Fungorum 2022), no molecular data available.
On leaves of Davilla rugosa (Dilleniaceae). Sexual morph: Ascostroma black, hypophyllous, stromatic, superficial, solitary to gregarious, globose, thick walled, papillate. Peridium composed of thick-walled, dark brown to hyaline cells of textura angularis. Hamathecium composed of asci and dense pseudoparaphyses. Pseudoparaphyses hyaline, dense, septate, filamentous, unbranched. Asci cylindrical. Ascospores 2-seriate, olivaceous to brown, ovate to oblong, rounded at both ends, uniseptate, constricted at the septa. Asexual morph: Coelomycetous. Conidiomata pycnidial on the lower side of the leaf, usually on the veins, superficial, gregarious, many on a stroma, globose or subglobose, black, ostiolate. Peridium composed of thick-walled cells of textura angularis, with outer 3–4-layers dark brown, inner 1–2-layers hyaline. Conidiophores reduced to conidiogenous cells. Conidiogenous cells holoblastic, integrated, terminal. Conidia olivaceous to dark brown, ellipsoid to biconic, with a hyaline equatorial band, unicellular, rounded at the apex and truncate at the base, smooth, thick-walled (adapted from Hyde et al. 2017).
Type species: Licopolia franciscana Sacc., Syd. & P. Syd.
Notes: Licopolia is characterised by black, hypophyllous, stromatic, superficial ascostroma, cylindrical asci and olivaceous to brown, ovate to oblong ascospores. The asexual morph is characterised by pycnidial conidiomata, holoblastic, integrated, terminal conidiogenous cells and olivaceous to dark brown, ellipsoid to biconic hyaline conidia. Hyde et al. (2017) re-examined a specimen of L. franciscana (S Reg. no. F46317) but did not observe asci. Hyde et al. (2017) found the asexual morph of L. franciscana from the same ascostroma. Licopolia is morphologically similar to Blasdalea disciformis in having ellipsoid to biconic and aseptate conidia with a hyaline equatorial band. Hyde et al. (2017) transferred Licopolia to Vizellaceae based on morphology. Fresh collections with DNA sequence data are needed to verify the taxonomic placement of Licopolia.
