Lonicericola hyaloseptispora Phookamsak, Jayasiri & K.D. Hyde, in Phookamsak et al., Fungal Diversity: 10.1007/s13225-019-00421-w, [40] (2019)

Index Fungorum number: 556140            Facesoffungi number: 04963

 

Sexual morph: Ascomata 170–240 µm high, 165–250 µm diam., black, scattered, solitary to gregarious, immersed under host epidermis, slightly raised, globose to subglobose, uni-loculate, glabrous, ostiolate, papillate. Ostioles centrally located, oblong, with minute papilla, with porelike opening, filled with hyaline periphyses. Peridium 8–25 µm wide, of equal thickness, composed of several layers, of flattened to broad, brown to dark brown, pseudoparenchymatous cells, arranged in textura angularis to textura prismatica. Hamathecium composed of numerous, 2–3.5 µm wide, filamentous, septate, anastomosed pseudoparaphyses, embedded in a hyaline gelatinous matrix. Asci (90–)100–120(–145) × (24–)25–30(–33) µm (x̄ = 115.1 × 27 µm, n = 30), 8-spored, bitunicate, fissitunicate, broadly cylindrical to cylindric-clavate, subsessile to short pedicellate, with furcate to obtuse pedicel, apically rounded, with ocular chamber clearly visible when young. Ascospores overlapping 2–3-seriate, hyaline, becoming brown when release from the asci, fusiform to vermiform, enlarged at the 4th cell from the apex (4–10 × 9–12 µm, l/w), (8–)9-septate, constricted at the septa, smooth-walled, with small to large guttules, surrounded by entire mucilaginous sheath (3.5–13 µm wide).

 

Asexual morph: Undetermined.

 

Known hosts and distribution: On decaying pod carpel of Leucaena sp. and Pterocarpus sp., Hevea brasiliensis (Thailand).

 

Culture characteristics: Colonies on PDA reaching 50–55 mm diam. after 3 weeks at room temperature (20–30

---

C). Colony dense, circular, flattened, slightly raised, surface smooth, with entire edge, floccose to fluffy; from above dark grey to brown; from below, black; not producing pigmentation on agar medium.
