Burgella flavoparmeliae
Burgella flavoparmeliae Diederich & Lawrey 2007, in Diederich & Lawrey, Mycological Progress 6(2), 62 (2007).
Diagnosis: Basidiomata and conidiomata unknown. Colonies appearing as dispersed or rarely agglomerate bulbils overgrowing lichen thalli. Mycelium not observed. Bulbils slightly immersed in the host thallus to superficial, dispersed, yellow to ochraceous or orange (honey-colored), ±shiny, without hairs, roundish to shortly ellipsoid or rarely irregular in form, 60–110 μm diam.; bulbils externally without specialized cells, cells in surface view polyhedral, smooth 6–12 μm diam.; bulbils internally composed of strongly adherent, more or less roundish to ellipsoid or polyhedral cells separating only with difficulty, 6–12 μm diam., clamps not observed; agglomerations of small crystals visible in polarized light present on the surface of all specimens examined.
Colonies in liquid culture showing abundant white aerial hyphae, from which orange agglomerations of bulbils arise. Hyphae hyaline, septate, straight, rarely branched or anastomosed, 2–3.5 μm thick; septa with or without clamp connections (both situations present on the same hyphae at neighbouring septa); dolipores visible by light microscope. Agglomerations of bulbils up to 1 cm diam., almost as tall as wide, greyish orange (Kornerup & Wanscher 1984:5B6), gelatinous in appearance, almost coralloid, composed of irregularly shaped bulbils of 150–300 μm; bulbils externally and internally composed of irregular, roundish or elongate cells with clamped septa, some with a pale orange content, 6–17×4–9 μm.
