    About this ebook

    This book focuses on two families of lichenized ascomycetes: Pyrenulaceae and Trypetheliaceae. It illustrated the majority of the accepted species in these families, which are most diverse on bark in tropical regions, most especially the Amazon. Fully updated dichotomous identification keys are given to all species in these families and to some similar groups and species, especially those in the same habitat, several of which are also illustrated in full. The illustrations are made from relatively recent material which still shows all characters, including gelatinous ascopore sheaths. For relatively recently described species, often type material is illustrated.

      Astrothelium himalayense (Upreti & Aptroot) Aptroot & Schumm Bogoriella oleosa (Aptroot) Aptroot & Schumm Pseudopyrenula kantvilasii (P.M. McCarthy) Aptroot

      Pyrenula hibernica (Nyl.) Aptroot & Etayo, in Etayo & Aptroot. Lichenologist 35(3): 235 (2003)

      = Anthacothecium hibernicum (Nyl.) A.L. Sm., Monogr. Brit. Lich. 2: 342(1911)

      = Polymastia hibernica (Nyl.) Arnold, Flora, Regensburg 53: 21 (1870)

      = Verrucaria pyrenuloides var. hibernica (Nyl.) Carroll, J. Bot., Lond. 6: 163 (1868)

      Thallus immersed, pale olive-green or yellow-buff, sometimes with white dots, smooth, continuous, with age becoming rougher and rarely cracked. Ascomata 1–2 m diam., black, arising 1–1.5 mm below the surface; only the pale ostiolum visible at surface, or ascomata visible through translucent surface of thallus; occuring singly, or radially arranged in groups of 2 to 5; ostioles lateral, often joined, visible as a pale yellow- or orange-brown depression, or level with surface of thallus. Asci 4- to 8-spored. Ascospores muriform, brown when mature, (57–)70–135(–140) × (24–) × 26–47(–55) μm, oblong to fusiform–ellipsoid. Pycnidia c. 2 mm diam., divided into chambers; conidia 24–27 × 1 μm. Chemistry: Thallus C-, K-, KC-, P-, UV+ pale yellow.

      [ABL61955], Scotland, Argyll, Sunart, Resipole, near Allt Mhic Chiarain river, on Corylus. 0–50 m. Leg. A. Aptroot (no 61955), 1830.07.2004, det. A. Aptroot, 2004.

      Pyrenula infracongruens Aptroot & Schumm, in Schumm & Aptroot, Seychelles Lichen Guide (Wangen); 280 (2010)

      Thallus yellowish grey, smooth, up to 0.4 mm thick, with a 20–40 μm thick hyaline cortical layer, UV- negative. Ascomata only visible by the grey ostiole, immersed in the thallus, globose to pyriform, c. 0.2–0.4 mm diam, surrounded by a thin carbonized wall which is thicker at the upper half and especially around the ostiole, suggesting a clypear origin. Hamathecium not inspersed. Ascospores 11–13 × 6–7 pm, 3–septate, rather variably coloured grey to brown, ellipsoid with parallel sides, mostly sharply pointed, end lumina in spore tips, central lumina often irregularly placed, rounded to angular.

      This is a species with ascospores of the pseudobufonia-type (with the end lumina in the ascospore tips) differing from Pyrenula nitidula by the much smaller spores, and from Pyrenula fetivica also by the absence of inspersión, and from both species by the thick, corticate thallus which hides most of the ascomata.

Resulting stromata superficial, black, often strongly contrasting in colour with the pale thallus. Ostiole apical, black or with whitish pruinose ring. Hamathecium not inspersed. Ascospores 8 per ascus, irregularly biseriate, 3-septate, 15—18(—22) × 5–7(–9) pm, ends often pointed, lumina angular to rounded, often wider than long, with a thick layer of endospore in the spore tips. Pycnidia not observed. Chemistry: No substances detected.

Ostiole lateral. Hamathecium inspersed with hyaline oil droplets.
