“…2C) (Aptroot and Lücking 2016). This new species seems to be closer related to species with hyaline ascospore (Architrypethelium lauropaluanum) than brown ascospores (A. nitens and A. uberinum) (Aptroot 1991, Aptroot et al 2008, Lücking et al 2016a. So far, all species in Architrypethelium had large, transversely septate ascospores (Aptroot and Lücking 2016).…”

“…Also the ascospore size (35-50 × 13-15.5 μm) differs from A. keralense (50-60 x 15-20 μm) and A. variatum (24-35 x 11-13 μm). The placement of the new species in Architrypethelium is supported by molecular evidence (Fig 1), but it is unlikely to be confused with any of the currently accepted species in that genus due to the differences in ascospore size and septation (Aptroot et al 2008, Aptroot and Lücking 2016, Flakus et al 2016, Lücking et al 2016a). The new taxon has muriform and relatively small ascospores (ca.…”

“…The new taxon has muriform and relatively small ascospores (ca. 50 μm, long) (Fig 2), whereas other Architrypethelium species have transversely septate ascospores (3-5 septate), that are longer than 90 μm (Aptroot 1991, Aptroot et al 2008, Aptroot and Lücking 2016, Flakus et al 2016, Lücking et al 2016a). …”

Architrypethelium murisporum (Ascomycota, Trypetheliaceae), a remarkable new lichen species from Thailand challenging ascospore septation as an indicator of phylogenetic relationships

Architrypethelium murisporum Luangsuphabool, Lumbsch & Sangvichien is described for a crustose lichen occurring in dry evergreen forest in Thailand. It is characterised by a green to yellow-green corticated thallus, perithecia fused in black pseudostromata with white rim surrounding the ostiole and small, hyaline and muriform ascospores. Currently, all species in the genus Architrypethelium have transversely septate ascospores, hence the discovery of this new species indicates that ascospore septation is variable within the genus, similar to numerous other groups of lichen-forming ascomycetes. Phylogenetic analyses of two loci (mtSSU and nuLSU) supported the position of the new species within Architrypethelium. This is the first report of the genus in Southeast Asia.

“…This also strongly suggests that many species still remain undiscovered, as shown by a statistical prediction exercise (Aptroot et al 2016c). This is corroborated by the fact that a few short field trips in small areas in Brazil yielded many undescribed species (Aptroot & Cáceres 2016;Aptroot et al 2016b;Lücking et al 2016a), and also taxonomic inventories of other understudied areas, such as Panama and Bolivia, unravelled numerous novel taxa Lücking et al 2016b).…”

A revisionary synopsis is presented for the family Trypetheliaceae, based on a separately published phylogenetic analysis of a large number of species, morpho-anatomical and chemical study of extensive material, and revision of numerous type specimens. A total of 418 species is formally accepted in this synopsis, distributed among 15 genera as follows: Aptrootia (3), Architrypethelium (7), Astrothelium (242), Bathelium (16), Bogoriella (29), Constrictolumina (9), Dictyomeridium (7), Distothelia (3), Marcelaria (3), Nigrovothelium (2), Novomicrothelia (1), Polymeridium (50), Pseudopyrenula (20), Trypethelium (16), and Viridothelium (10). All accepted genera, including new genera described separately in this issue, are keyed out and briefly described and discussed, and keys are provided for all accepted species within each genus. Entries with full synonymy and brief descriptions, and in part also discussions, are provided for all accepted species, except those newly described elsewhere in this issue, which are cross-referenced in the corresponding keys. The description of the newly defined genera takes into account phylogeny in combination with morpho-anatomical features with the result that they are mostly recognizable by a combination of thallus, ascoma and ascospore features. Most species previously assigned to the genera Astrothelium, Campylothelium, Cryptothelium, and Trypethelium, based on a schematic concept of ascoma morphology and ascospore septation, are now included in a single genus, Astrothelium, with highly variable ascoma morphology and ascospore septation but invariably with astrothelioid ascospores (at least when young), that is diamond-shaped lumina, and a welldeveloped, corticate, usually olive-green thallus that often covers the ascomata. While the genera Aptrootia (large, brown, muriform ascospores), Architrypethelium (large, mostly 3-septate ascospores), and Pseudopyrenula (ecorticate, white thalli and astrothelioid ascospores) are maintained, Trypethelium is redefined to include species with raised, pseudostromatic ascomata and multiseptate ascospores with thin septa. The sister group of Trypethelium is the genus Marcelaria, with brightly coloured pseudostromata and muriform ascospores. Bathelium is now limited to species with strongly raised, fully exposed pseudostromata and septate to muriform ascospores with thin septa. Several genera are recognized for more basal lineages with mostly ecorticate, white thalli and solitary, exposed ascomata previously assigned to Arthopyrenia, Mycomicrothelia and Polymeridium, viz. Bogoriella, Constrictolumina, Dictyomeridium, and Novomicrothelia. In addition, separate genera are accepted for the Trypethelium tropicum (Nigrovothelium) and T. virens (Viridothelium) groups. In addition, a refined species concept resulting from phylogenetic studies is employed which pays particular attention to morphological features of the thallus and ascomata. Of a total of 526 names checked, 107 remain synonyms of accepted names and a further eight are newly excl...

The genus Dendriscosticta (Ascomycota: Peltigerales) encompasses several distinctive lichen-forming fungal species restricted to the Northern Hemisphere. Most are flagship species of old-growth forests with good air quality. A global phylogeny of the genus based on multilocus sequence data (ITS, RPB1, EF-1α, MCM7), model-based phylogenetic methods, and morphological and chemical assessments, reveals a high level of cryptic speciation often associated with restricted geographical distribution and/or chemical characters. Using sequence-based species delimitation approaches, we circumscribe two main clades referred to as the D. wrightii clade, with five unequivocal species, including D. gelida sp. nov., and the D. praetextata clade, with eight putative species, including D. phyllidiata sp. nov. The absence of recently collected material of D. hookeri comb. nov. from the type locality unfortunately prevents assignment of this epithet to one of the five supported lineages sharing this morphotype. Three new combinations are proposed: D. hookeri, D. insinuans comb. nov. and D. yatabeana comb. nov. Epitypes are designated for D. wrightii and D. yatabeana. Species diversity within the genus increased from four to nine. Our morphological assessment confirmed that Sticta and Dendriscosticta can be readily distinguished by the presence of excipular algae whereas the structure of the lower surface pores is not a reliable diagnostic feature.
