“…It is for instance notable that the biota of another essentially tropical genus, viz. Pyrenula , in central Iran (one of the areas with a similar climate) was found to be surprisingly rich in species for a mostly dry subtropical country (Aptroot et al 2012). Based on this, we can almost predict a similar Pyrenula diversity in Portugal.…”

Five Graphis species are reported as new to Europe from the Mata Nacional do Buçaco, a region in Portugal where graphidoid Graphidaceae are abundant and diverse. The following species were identified: Graphis dendrogramma, G. duplicata, G. gonimica, G. librata and G. pyrrhocheiloides. An updated key is given to the Graphis species known from Europe. All those newly reported were identified with names corresponding to tropical species.

“…The presence or absence of pseudocyphellae seems to be a rather fundamental character within the genus Pyrenula, as it is the only morphological character that is well correlated with the basal split within the genus following a preliminary phylogenetic reconstruction (Weerakoon et al 2012). The ascospores in the new species are among the smallest known in the genus, with only Pyrenula minutissima Aptroot et al (Aptroot et al 2012) having smaller ascospores (7-10 mm long). (Fig.…”

Five new species of corticolous pyrenocarpous lichens are described from tropical and subtropical forests in the Chaco and Misiones provinces in NE Argentina: Aspidothelium submuriforme with globose, grey ascomata and ascospores mostly 7-septate with 0–2 oblique longitudinal septa, 25–28×8–10 µm; Pyrenula inspersoleucotrypa, characterized by a thallus without pseudocyphellae, aggregated ascomata, an inspersed hamathecium, and ascospores of 17–20×6·5–8·0 µm with diamond-shaped lumina; Pyrenula punctoleucotrypa, which has a thallus with pseudocyphellae, aggregated ascomata in a conical pseudostroma, with fused ostioles, not inspersed hamathecium, and ascospores of 10–12×4–5 µm with rounded lumina; Strigula muriconidiata, containing immersed pycnidia with hyaline, densely muriform, ellipsoid conidia, 90–103×32–35 µm; Trypethelium globolucidum, forming sessile pseudostromata with black and whitish parts, an inspersed hamathecium, ascospores 13–19-septate, (65–)83–97×11·5–14·5 µm, lumina rounded to lentiform and containing lichexanthone.

“…Pyrenula rubromarginata differs from other species with red pigment on the perithecia and not on the thallus by the combination of the following characters: dispersed, superficial, conical perithecia, small, 3-septate, uniseriate ascospores with thick apical walls. P. howeana Aptroot (Aptroot 2007) is most similar by the redpigmented, conical, superficial perithecia and non-pigmented thallus with small, irregularly biseriate ascospores and deviates by its slightly larger ascospores, 15-20 × 7-10 μm, with thin terminal walls and a guttulate hamathecium. The only other species with red-pigmented, prominent perithecia and unpigmented thallus is P. rubroanomala Aptroot & Lücking (Aptroot et al 2008), in which the perithecia are fused in distinct pseudostromata, not dispersed or few aggregated, and the spores measure 15-17 × 5-6 μm.…”

Four new species of the genus Pyrenula (Pyrenulaceae, Pyrenulales, lichenized Ascomycetes) are presented. They originate from primary forests in the Guianas: Pyrenula cubica Sipman, with cubical central lumina in the ascospores; Pyrenula flavida Sipman, with a yellow-pigmented thallus; P. rubromarginata Sipman, with red pigment on the excipulum and not on the thallus; and P. submicromma Sipman, like P. micromma but with submuriform instead of bacillar ascospores. In addition, a description for P. atropurpurea is provided, and P. subvariabilis is reduced to synonymy of P. infrastroidea. Special attention was paid to the development of the ascospores. Two different development types are recognized. The phylogenetic significance of these types is unclear.
