Roccellinastrum spongoideum

Ciri dan struktur

Thallus usually 2 cm large but specimens up to 7 cm were observed, gray to brownish gray, sub- fruticose, byssoid-spongiose or cottony-granular. Lobes tubular, up to 20 mm long or longer, cylindrical and up to 5 mm broad or flattened and up to 6 mm broad, partly fenestrate in older parts. Young thalli at first as erect tufts developing to hollow tubes covered with white to light pink or brownish apothecia which are laminal, up to 0.5 mm broad, frequently compound, sessile or shortly stipitate. Hymenium 35–45 µm high, paraphyses branched, hypothecium colorless. Asci 26–35 × 8–10 µm, spores 1-septate at maturity, 7.5–10 × 1.5–3 µm. Excipulum of (often dichotomously) branched, radiating hyphae with strongly gelatinized walls, colorless, not sharply delimited from the paraphyses. Single hyphae often form loop structures in inner thallus parts. Thallus hyphae 3–9 µm wide, lumina ca. 1 µm thick. Cell lumina elongated or short, the ends sometimes characteristically enlarged adjacent to septa. Cells of the Symbiochloris photobionts (= ‘micareoid’) of 8–10 µm in diameter, arranged in nests of several cells.
