“…Most of the formally described species of Ceratocystiopsis are known only from conifers although C. lunata and C. synnemata were recently collected from hardwood-infesting beetles (Li et al 2018;Strzałka et al 2020;Nel 2021). The results of the present study con rm that in general there is a close a nity of Ceratocystiopsis species to conifers.…”

“…As currently circumscribed Ceratocystiopsis accommodates 20 recognized species (De Beer et al 2013a;Strzałka et al 2020;Nel et al 2021;Chang et al 2021), which are characterized by ascocarps that have short necks, and produce falcate ascospores surrounded by a hyaline sheath (De Beer and Wing eld 2013). According to De Beer and Wing eld (2013), Ceratocystiopsis species besides falcate ascospores (type E, F) may also produce cucullate ascospores (typ G), in addition Ceratocystiopsis spp.…”

“…Siemaszko (1939) based O. minutum on the characterization of perithecia found on the wood of Picea abies infested with Ips typographus in the Białowieża Forest (Poland), Siemaszko did not describe a conidial state for this fungus. The taxonomy of this group has a turbulent history, and species of Ceratocystiopsis (Ascomycota, Ophiostomatales, Ophiostomataceae) have been accommodated in various genera including Ceratocystiopsis (Upadhyay 1981;Marmolejo and Butin 1990;Hsiau and Harrington 1997;Zipfel et al 2006;Strzałka et al 2020;Nel et al 2021), Ceratocystis (Gri n 1968;Olchowecki and Reid 1974), Cornuvesica (Viljoen et al 2000), and Ophiostoma (Siemaszko 1939;Hausner et al 1993Hausner et al , 2003Kirschner and Oberwinkler 1999). Important historical developments in the taxonomy of Ceratocystiopsis include: 1) erecting the genus Ceratocystiopsis for species that have falcate ascospores with sheaths and short perithecial necks (Upadhyay and Kendrick (1975); 2) reducing Ceratocystiopsis to synonymy with Ophiostoma, based on partial SSU and LSU rDNA sequences (Hausner et al 1993); 3) re-instating Ceratocystiopsis to accommodate taxa that have short ascomatal necks, produce falcate ascospores with sheaths and have Hyalorhinocladiella (occasionally sporothrix-like) anamorphs.…”

“…The genus Ceratocystiopsis has a wide geographic distribution, including records for Africa (Nel et al 2021), Asia (e.g., Yamaoka et al 1997;Wang et al 2020;Chang et al 2021), Europe (e.g., Hausner et al 1993;Kirisits 2004, Jankowiak 2005Linnakoski et al 2012;) and North America (Olchowecki and Reid 1974;Bridges and Perry 1987;Marmolejo and Butin 1990;Hsiau and Harrington 1997;Hausner et al 2003). They are abundant in the Northern Hemisphere, especially in conifer ecosystems in Europe and North America.…”

The genus Ceartocystiopsis includes ascomycetes fungi belonging to the Ophiostomatales that are not well recognized in the world. Described species so far have been found mainly in association with bark beetles in the Northern Hemisphere. The aims of this study were therefore to survey of distribution of species of Ceratocystiopsis associated with bark beetles infesting Picea abies and Pinus sylvestris in Norway. Adults for 22 different bark beetle species were collected from 13 stands in Norway. During this study, we recovered 126 isolates showing affinities to Ceratocystiopsis representing six species, including two described and four undescribed taxa. The four undescribed taxa collected during this work were characterised based on their morphological characteristics and multi-gene phylogenies. Herein, we describe these new species as Ceratocystiopsis chalcographii sp. nov., Ceratocystiopsis debeeria sp. nov., Ceratocystiopsis norroenii sp. nov. and Ceratocystiopsis troendelagii sp. nov. Ceratocystiopsis norroenii and C. rollhanseniana were the most frequently isolated species although the latter species had a much wider vector range. This study expands our knowledge about the taxonomy and species diversity of Ceratocystiopsis and beetle-fungus relationships.

“…Another family of wood-boring beetles with a close relationship with fungi are the Bostrichidae. Their symbiosis with Geosmithia fungi (Kolarik, Kostovik & Pazoutova, 2007;Kolarik et al, 2017) and with Ophiostoma fungi (Nel et al, 2021) (both Ascomycota: Sordariomycetes) has only been reported anecdotally, explaining its omission from a previous review (Biedermann & Vega, 2020). Nevertheless, all obligate ambrosia relationships begin with a facultative association and we therefore include bostrichid beetles herein, as potentially representing an early stage in a symbiosis with ambrosia fungi (Figs 1, 2B).…”

Origin and evolution of fungus farming in wood‐boring Coleoptera – a palaeontological perspective

2021

Insect-fungus mutualism is one of the better-studied symbiotic interactions in nature. Ambrosia fungi are an ecological assemblage of unrelated fungi that are cultivated by ambrosia beetles in their galleries as obligate food for larvae. Despite recently increased research interest, it remains unclear which ecological factors facilitated the origin of fungus farming, and how it transformed into a symbiotic relationship with obligate dependency. It is clear from phylogenetic analyses that this symbiosis evolved independently many times in several beetle and fungus lineages. However, there is a mismatch between palaeontological and phylogenetic data. Herein we review, for the first time, the ambrosia system from a palaeontological perspective. Although largely ignored, families such as Lymexylidae and Bostrichidae should be included in the list of ambrosia beetles because some of their species cultivate ambrosia fungi. The estimated origin for some groups of ambrosia fungi during the Cretaceous concurs with a known high diversity of Lymexylidae and Bostrichidae at that time. Although potentially older, the greatest radiation of various ambrosia beetle lineages occurred in the weevil subfamilies Scolytinae and Platypodinae during the Eocene. In this review we explore the evolutionary relationship between ambrosia beetles, fungi and their host trees, which is likely to have persisted for longer than previously supposed.

Ceratocystiopsis spp. associated with pine- and spruce-infesting bark beetles in Norway

et al. 2022

View full text Add to dashboard Cite

The genus Ceratocystiopsis (Ophiostomatales, Ascomycota) includes 21 species, which can be found mainly in association with bark beetles in the Northern Hemisphere. A survey of Ceratocystiopsis species associated with bark beetles infesting Picea abies and Pinus sylvestris in Norway yielded 126 isolates, representing Ceratocystiopsis neglecta and Ceratocystiopsis rollhanseniana, and four species described herein as Ceratocystiopsis chalcographii, Ceratocystiopsis debeeria, Ceratocystiopsis norroenii and Ceratocystiopsis troendelagii. The new taxa were morphologically characterised and phylogenetically analysed on the basis of sequence data of multiple loci (ITS, LSU, beta-tubulin (TUB2), calmodulin (CAL) and translation elongation factor 1-alpha (TEF1) genes). Ceratocystiopsis norroenii and C. rollhanseniana were the most frequently isolated species, and the latter species had the wider vector range.
