Megalaria pachaylenophila

Ciri dan struktur

Similar to Megalaria bengalensis, but differs in an ochre to brownish apothecial disc (black in M. bengalensis) and in lacking isidia and secondary products (atranorin in M. bengalensis). Thallus crustose, corticolous, gray to olive-gray or greenish gray, up to 10 cm in diameter, smooth, cracked, without soredia or isidia. Apothecia biatorine, plain and flat, becoming slightly convex with age, circular in outline or becoming deformed, sessile, 0.3–0.8 mm in diameter; margins black, shining, contrasting strongly with the coloration of the discs; discs beige to brownish, epruinose. Epihymenium 2–5 μm thick, not pigmented or light beige, K–, N–. Hymenium 75–100 μm thick, hyaline, not inspersed. Subhymenium 10–20 μm thick, hyaline. Central hypothecium 50–80 μm thick, pigmented red-brown, K+ wine-red, N–; lateral hypothecium blue to blue-black, K–, N+ purple. Excipulum 15–25 μm thick, comprised of thick, gelatinized hyaline to blue hyphae, not inspersed with crystals, K–, N+ purple. Asci cylindrical to clavate, eight-spored; ascospores narrowly ellipsoid, hyaline, one-septate (rarely simple), thin walled, not halonate, (9–)11–15 × 4–5 μm. Pycnidia not seen. Secondary metabolites. Thallus K–, C–, and KC–, UV–, no lichen substances found using TLC.
