Rhytidhysteron mesophilum

Ciri dan struktur

Differs from Rhytidhysteron rufulum by its green-yellowish pruina on the margins, size of asci (267–282 × 15.5–16 μm) and larger ascospores (40–44 × 12–14 μm). Ascomata hysterothecial to apothecial, 2.5–4 mm long, 1.0–1.5 mm wide, 1.4–1.7 mm high, superficial or erumpent, gregarious, rarely solitary, with small hysterothecial ascomata, ellipsoid to oblong and black when young, then boat-shaped hysterothecia, with some constriction in the middle part, flexuous, open in apothecioid ascomata, dark green (30F3–4), dull green (30E3–4), greyish green (30E6–7), deep green (30D-E8) to yellowish green (30B-C8) when mature, forming small ascomata within disc in old specimens. Margin involute, perpendicularly striate, marks are not roughness, rather irregular slits, with yellowish green (30B-C8) pruina. Exciple integrated in two layers, the first carbonaceous, glabrous, green yellowish, 62.5–75 μm thick, in the middle part widening more (112.5–125 μm), composed of pseudoparenchymal cells of textura prismatica (iso-radiating cells), the second composed of cells hyaline, thin-walled. Pseudoparaphyses 2.0–2.5 μm up to 3.0 μm wide, filamentous, capitate, hyaline, without septa, branched towards the apex, enclosed in a gelatinous matrix, strongly anastomosed above the asci. Epithecium reddish orange (7B8) to orange red (8A8), becoming greyish magenta (13D6) in the presence of 10% KOH. Asci 267–282 × 15.5–16 μm, bitunicate, cylindrical, hyaline, uniseriate, octosporic, thick-walled, with a sinuous base. Ascospores (38–)40–44(–46) × 12–14 μm, (x̄= 44.2 × 13.6, n = 30), ellipsoidal to oblong, light brown in colour, with three transverse septa, constricted at the septa, with a thick and smooth wall.
