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, Selleckchem Capmatinib 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 Hippo pathway inhibitor ascospores with distoseptate thickenings at selleck inhibitor maturity”, and is 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). (Pleosporales, 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, Adenosine triphosphate 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.)
