Fungal Diversity times furcate pedicel, up to 13 μm long, ocular chamber not observed (Fig. 47f, g, h and k). Ascospores 16–20×9– 11 μm (x ¼ 18 10mm, n=10), biseriate, ellipsoidal, pale orange-brown, 1-distoseptate, with prominent swelling at the septum, containing refractive globules, smooth (Fig. 47i, jandl). Anamorph: The following description is from Calatayud et al. (2001). Conidiomata pycnidial, arising in galls together with the ascomata, immersed, ca. 100–200 μm diam.; wall dark brown throughout, composed of 2–5 layers of angular to laterally compressed cells; cells relatively large, ca. 8– 16 μm diam. in superficial view. Conidiophores formed by 1–3 cells, frequently branched and with the uppermost cells bearing 1–4 conidiogenous cells; cells±cylindrical, hyaline except at the base, which are sometimes pale brown, 7–15× 3–4 μm. Conidiogenous cells tapered towards the apex, 14– 18×3–4 μm. Conidia 5–7×1.5–2 μm. Vegetative hyphae hyaline. Material examined: SPAIN, Andalucía, Province, Jaén, Andújar, lichenicolous on Leptochidium albociliatum (Desm.) M. Choisy on acid volcanic rock, 19 Apr. 2000, V. Calatayud (MA-Lichen 12715, holotype). Notes Morphology Lichenopyrenis was formally established by Calatayud et al. (2001) based on its “perithecioid ascomata with peridium comprising compressed cells, fissitunicate and J- asci, wide hamathecium filaments, and 1-septate pale orange-brown ascospores with distoseptate thickenings at maturity”, andis monotypic with L. galligena. The genus was temporarily assigned to Pleomassariaceae. Lichenopyrenis galligena is a parasite of lichens, occurring in galls in the thallus of the host (Calatayud et al. 2001). Phylogenetic study None. Concluding remarks This is one of the few species that are parasitic on lichens. The most comparable species are Parapyrenis lichenicola Aptroot & Diederich and Lacrymospora parasitica Aptroot (both in Requienellaceae, Pyrenulales) as well as some species from Dacampiaceae. The peridium structure, cellular pseudoparaphyses, distoseptate and smooth, orange-brown ascospores as well as the anamorphic stage of Lichenopyrenis can easily distinguish from all of them (Calatayud et al. 2001). Lineolata Kohlm. & Volkm.-Kohlm., Mycol. Res. 94: 687 (1990). (<strong>Pleosporales</strong>, genera incertae sedis) Generic description Habitat marine, saprobic (or perthophytic?). Ascomata medium-sized, gregarious, immersed to erumpent, obpyriform, ostiolate, papillate. Peridium thin, comprising two types of cells; outer cells thick stratum pseudostromatic, inner stratum thin, composed of a few layers of hyaline cells of textura angularis. Hamathecium of dense, long trabeculate pseudoparaphyses, embedded in mucilage, anastomosing and septate. Asci 8-spored, bitunicate, cylindrical, with short pedicels, with an ocular chamber. Ascospores uniseriate to partially overlapping, ellipsoidal, dark brown, 1-septate. Anamorphs reported for genus: none. Literature: Kohlmeyer and Kohlmeyer 1966; Kohlmeyer and Volkmann-Kohlmeyer 1990. Type species Lineolata rhizophorae (Kohlm. & E. Kohlm.) Kohlm. & Volkm.-Kohlm., Mycol. Res. 94: 688 (1990). (Fig. 48) ≡ Didymosphaeria rhizophorae Kohlm. & E. Kohlm. Icones Fungorum Maris (Lehre) 4 & 5: tab. 62a (1967). Ascomata 300–490 μm high×200–360 μm diam., gregarious, immersed to erumpent, obpyriform, ostiolate, papillate, subcarbonaceous to subcoriaceous, blackish brown (Fig. 48a). Peridium 37–45 μm thick, comprising two types of cells; outer cells thick stratum pseudostromatic, composed of irregular or roundish, dark brown cells, on the outside with a more or less recognizable hyphal structure, enclosing some decaying cells of the host, inner stratum thin, composed of four or five layers of hyaline, polygonal, elongate, thin-walled cells with large lumina, merging into the pseudoparaphyses. Hamathecium of dense, long trabeculate pseudoparaphyses, 1–1.5 μm broad, embedded in mucilage, anastomosing and septate. Asci 150–175×14–17.5 μm, 8-spored, bitunicate, cylindrical, with short pedicels, with an ocular chamber (Fig. 48b). Ascospores 23–32(−33)×9–12 μm, uniseriate to partially overlapping, ellipsoid, dark brown, 1-septate, not or slightly constricted at the septum, striate by delicate costae that run parallel or in a slight angle to the longitudinal axis of the ascospore (Fig. 48c, d, e and f) (adapted from Kohlmeyer and Kohlmeyer 1979). Anamorph: none reported. Material examined: US, Florida, Middle Torch Key, on Rhizophora mangle, 21 Nov. 1965, J. Kohlmeyer (Herb. J.
