Abstract

The bryophilous ascomycete Octospora pannosa is presented based on ecological and morphological data from two localities in Germany and Serbia. So far members of the genus Brachytheciastrum or the family Brachytheciaceae have not been reported as host for species of Octospora or related genera. The ascospore ornamentation of the new species consists of a ragged reticulum and is unique within all genera of the bryophilous Pezizales.

... Herbarium acronyms follow Thiers (2020). Nomenclature of bryophilous Pezizales corresponds to recent works such as Benkert (1998), Vega et al. (2018) and Sochorová et al. (2019). Nomenclature of European, North American, and South African bryophytes follows Hodgetts et al. (2020), Flora of North America Editorial Committee (2014), and O'Shea (2006), respectively. ...

Eckstein, J., Sochorová, Z. & Janošík, L. 2021. Octospora oscarii spec. nov. (Pezizales), a bryophilous ascomycete on the pleurocarpous moss Pseudotaxiphyllum elegans (Hypnales). – Herzogia 34: 286 –298. The bryophilous ascomycete Octospora oscarii is described as a new species based on collections from Central Germany and the Czech Republic. It grows on the pleurocarpous moss Pseudotaxiphyllum elegans and is characterised by smooth ascospores and an infection on the rhizoids of its host. This is the first account of P. elegans as a host of bryophilous ascomycetes. Phylogenetic analyses of concatenated LSU, SSU and EF1-α gene sequences showed that the studied collections of this species form a well-supported monophyletic lineage differing from all previously studied species of bryophilous Pezizales. Macroscopic and microscopic features of the new species are illustrated by colour photographs and drawings, and are compared to those of the other species of bryophilous Pezizales similarly growing on pleurocarpous mosses.
... They grow on species of the moss genus Orthotrichum, which was formerly placed in the Neckerales but today is placed in the Orthotrichales (Goffinet et al. 1998, Goffinet et al. 2008. Recently, two more species on Hypnales were described: Octospora pannosa on Brachytheciastrum velutinum Hedwig (1801: 272) Ignatov & Huttunen (2002 (Vega et al. 2018) and O. conidiophora on trichosteleum perchlorosum Brotherus & Bryhn in Bryhn (1911: 24) and Sematophyllum brachycarpum (Hampe 1844: pl. 11) Brotherus in Engler & Prantl (1925: 431) (Sochorová et al. 2019). ...

The bryophilous ascomycete Octospora svrcekii, belonging to the section Wrightoideae, has so far been reported from only three localities in the world. New collections from Albania, Austria, Croatia, France, Slovakia and Spain have enabled a better understanding of its variability, ecology, distribution and phylogenetic relationships with other taxa within the section Wrightoideae. Octospora svrcekii was always found associated with Cratoneuron filicinum growing in constantly humid habitats (brooks, rivers or waterfalls), on calcareous bedrock. A species description based on both living and dead material is provided and compared with previous observations. A phylogenetic analysis of the section Wrightoideae, performed using the EF1α, SSU rDNA and LSU rDNA loci, revealed that Octospora svrcekii forms a monophyletic group with O. wrightii, O. erzbergeri, O. hygrohypnophila and O. americana, all of which are characterised by subglobose to broadly ellipsoid ascospores ornamented with isolated warts, and infect mosses in the order Hypnales, inducing galls on their rhizoids. Based on the molecular analysis, O. orthotrichi and O. affinis, formerly also considered as members of the section Wrightoideae, do not belong to the group.
... Additionally, noteworthy are data of two new recently described species on the basis of samples collected in Serbia. These are Tuber petrophilum and Octospora pannosa (Vega et al. 2018). ...

Eckstein J, Eckstein G, Frauenberger H, Wieschollek D 2020: A first checklist of bryoparasitic Pezizales of Thuringia. Boletus 41: 51-64. A first checklist of bryoparasitic Pezizales of Thuringia is presented. The list contains 57 taxa. Lamprospora ditrichi is new to Germany and L. densireticulata, L. hanffii, L. tortulae-ruralis, L. tuberculatella, Neottiella ricciae, Octospora grimmiae, O. musci-muralis var. neglecta, O. pannosa, O. pseudoampezzana und O. rubens are new records for Thuringia. The frequency and the host bryophytes of Thuringian records are stated for each species. Additionally, a list of all host bryophytes from Thuringia is provided to facilitate searching for and identification of the bryoparasitic Pezizales.

SUMMARY The moss flora of Europe and Macaronesia comprises 278 genera, 1292 species, 46 subspecies and 118 varieties. Of the total 1292 species, 53 are confined to Macaronesia and 21 are thought to be non-native. The checklist was derived from those for the various component countries and regions. It is based on results published up to the end of 2005. Subspecies and varieties are included; hybrids are omitted. The taxonomic hierarchy is based on one published by Goffinet & Buck in 2004. While it has been strongly influenced by results of modern molecular methods, there are still many remaining uncertainties, even at family level. Because of these uncertainties, taxonomic innovation has generally been avoided. There are four new combinations and one change of status.
Book
The checklist of the flora of Germany contains the accepted names of the vascular plants found in Germany, including hybrids, synonyms in the floristic literature (under construction), distribution in the federal states (under construction), status of the occurrences, information on the pronunciation of the scientific names, German names (under construction) and quotations of the first descriptions (under construction). Not included are those plants occurring in cultivation only. The version 10 documented here was published on August 18, 2018 at https://www.kp-buttler.de/. It contains 62,620 names, 11,530 of which are accepted taxa and 51,090 are synonyms.

Molecular relationships within the Bryopsida are inferred from a new approach, i.e., the combined analysis of solely non-coding plastid markers (trnLUAA intron, atpB-rbcL spacer, psbA-trnH spacer). The current state of moss systematics is discussed with respect to the impact of this approach as well as other recently published molecular phylogenies and phylogenomic inferences. Taking into account the progress that has been made in the last few years by analysing molecular and non-molecular data, a new synopsis of the suprageneric classification of the Bryophyta is presented. Taxonomic changes comprise a re-evaluation of the taxonomy of Takakia (including Takakiophytina stat. nov.), Gigaspermidae subclass. nov., elevation of subfamilies of Dicranaceae to family level (Amphidiaceae stat. nov., Dicranellaceae stat. nov., Oncophoraceae stat. nov.), Hypodontiaceae fam. nov. and Helicophyllales ord. nov.
