Hypomyces peltigericola sp. nov. is described and illustrated based on material collected in France
on thalli of the lichen Peltigera canina. In culture the ascospores yielded a cladobotryum-like asexual morph
that was sequenced. The placement of this new species in the aurofusarin-group of the genus Hypomyces is
based on the combination of morphol...

... Hypomyces species that parasitize boletes or agarics exhibit host specificity (Rogerson & Samuels 1989, Tamm & Põldmaa 2013. Hypomyces species have been reported to occur occasionally in association with various plant substrates such as bark, wood, and leaves, as well as other substrates including moss, humus, rock, insect galls, and lichens (Rogerson & Samuels 1993, 1994, Lechat et al. 2017, Farr et al. 2021, Karimi et al. 2022, Perera et al. 2023. Members of Hypomyces have a wide distribution and can be found in temperate, tropical, and subtropical regions (Põldmaa 1996, 2003. ...
Hypocreales comprise a diverse group of fungi that exhibit a wide range of lifestyles in both aquatic and terrestrial environments.
A significant number of the identified fungicolous taxa belong to Hypocreales. Samples were collected from Chiang
Rai and Chiang Mai Provinces during an investigation on fungicolous fungi in northern Thailand. Based on morphological
characteristics and multi-gene phylogenetic analyses of ITS-LSU-tef1α-rpb2 and ITS-LSU-tub2-tef1α, two isolates were
identified as Hypomyces sichuanensis (Hypocreaceae) and Mariannaea humicola (Nectriaceae) respectively. This study
marks the first documentation of Hypomyces sichuanensis and Mariannaea humicola as fungicolous species from Thailand.
Additionally, the study reveals a novel host record for M. humicola on Marasmius sp.
... After the comprehensive studies by Rogerson and Samuels [12][13][14][15] and Põldmaa and collaborators [11,[16][17][18][19][20][21][22], the generic concept of Hypomyces became clear. Among the 212 names listed in Index Fungorum database, about 77 species are commonly accepted [11,[23][24][25][26][27][28][29]. Twenty-seven of them have been known from China [27,[29][30][31]. ...
To explore species diversity of Hypocreaceae, collections from Guangdong, Hubei, and Tibet of China were examined and two new species and a new Chinese record were discovered. Morphological characteristics and DNA sequence analyses of the ITS, LSU, EF-1α, and RPB2 regions support their placements in Hypocreaceae and the establishments of the new species. Hypomyces hubeiensis sp. nov. is characterized by occurrence on fruitbody of Agaricus sp., concentric rings formed on MEA medium, verticillium-like conidiophores, subulate phialides, rod-shaped to narrowly ellipsoidal conidia, and absence of chlamydospores. Trichoderma subiculoides sp. nov. is distinguished by effuse to confluent rudimentary stromata lacking of a well-developed flank and not changing color in KOH, subcylindrical asci containing eight ascospores that disarticulate into 16 dimorphic part-ascospores, verticillium-like conidiophores, subcylindrical phialides, and subellipsoidal to rod-shaped conidia. Morphological distinctions between the new species and their close relatives are discussed. Hypomyces orthosporus is found for the first time from China.
Hypomyces is an important genus of fungicolous fungi associated with different ascomycetes
and basidiomycetes. Numerous researchers have conducted morphological and molecular studies
on this genus. In this study, we collected submerged branches of Fagus sp. from Mazandaran
Province in Iran, from which a fungal isolate was obtained. Morphology coupled with maximum
likelihood and Bayesian inference analyses of the combined ITS, LSU, and rpb2 sequence data
showed it is a novel taxon (Hypomyces iranica). The morphology of the newly described species is
compared with its sister taxa, and a comprehensive description and micrographs are provided.
Hypomyces is a large genus of fungicolous fungi, parasitising the fruiting bodies of Agaricales, Boletales, Helotiales, Pezizales and Polyporales. Hypomyces currently comprises of 147 species widely distributed in Australia, China, France, Germany, Italy, Japan, North America, Sri Lanka, Thailand and UK. Amongst them, 28 species have been recorded in China.
Hypomyces pseudolactifluorum sp. nov., growing on the fruiting bodies of Russula sp. in subsect. Lactarioideae and collected from Yunnan, China, is described with illustrations and molecular phylogenetic data (combined ITS, LSU, TEF1 - α and RPB2 sequence dataset). The new species is characterised by semi-immersed to immersed perithecia and fusiform, apiculate and verrucose ascospores. We also review the species diversity of the genus Hypomyces in China.
Lichenicolous fungi represent a highly specialized and successful group of organisms that live exclusively on lichens, most commonly as host-specific parasites, but also as broad-spectrum pathogens, saprotrophs or commensals. We present here the most recent update to the classification of lichenicolous fungi in the Ascomycota and Basidiomycota to genus level, arranged phylogenetically according to published classifications. For each genus, all known lichenicolous taxa (obligately lichenicolous taxa, lichenicolous lichens, and facultatively lichenicolous taxa) are listed, along with information about types, synonyms, pertinent literature and whether or not molecular data are available for any of the listed species. The number of accepted lichenicolous fungi is now 2319, with 2000 obligately lichenicolous species, subspecies or varieties, 257 lichenicolous lichens and 62 facultatively lichenicolous taxa. These species are found in 10 different classes of Fungi (Ascomycota and Basidiomycota), 55 orders, 115 families and 397 genera. The 2319 total taxa is an increase from the 1559 total species reported in the last published catalogue in 2003, and a larger number than the approximately 1800 reported in the most recent online checklist (www.lichenicolous.net) posted in January 2018. Of the total number of taxa, 2219 (96%) are ascomycetes and 100 (4%) are basidiomycetes. Of the 397 genera containing lichenicolous species, c. 50% (198) are entirely lichenicolous. In addition, six families (Abrothallaceae, Adelococcaceae, Cyphobasidiaceae, Obryzaceae, Polycoccaceae, Sarcopyreniaceae) and two orders (Abrothallales, Cyphobasidiales) are entirely lichenicolous. Sequence information is available for lichenicolous species in 128 (32%) of the 397 genera containing lichenicolous species, and in 56 (28%) of the 198 entirely lichenicolous genera. Many species are known from only one host lichen, but it is likely that broader host ecologies will be discovered as new sequence information is obtained from ongoing microbiome studies. Phaeopyxis Rambold & Triebel is considered as a new synonym of Bachmanniomyces D.Hawksw., resulting in five new combinations B. australis (Rambold & Triebel) Diederich & Pino-Bodas (≡ P. australis), B. carniolicus (Arnold) Diederich & Pino-Bodas (≡ Biatora carniolica), B. muscigenae (Alstrup & E.S.Hansen) Diederich & Pino-Bodas (≡ P. muscigenae), B. punctum (A.Massal.) Diederich & Pino-Bodas (≡ Nesolechia punctum) and B. varius (Coppins, Rambold & Triebel) Diederich & Pino-Bodas (≡ P. varia). As a consequence of a phylogenetic analysis including new sequences, Dactylospora Körb. is regarded as a new synonym of Sclerococcum Fr.: Fr., resulting in one new name (S. acarosporicola Ertz & Diederich) and 46 new combinations. Sclerococcaceae Réblová, Unter. & W.Gams is considered as a new synonym of Dactylosporaceae Bellem. & Hafellner. The new Sclerococcum ophthalmizae Coppins is described. Sclerophyton occidentale Herre is lectotypified on the lichenicolous fungus present in the type specimen and becomes a younger synonym of Sclerococcum parasiticum. A replacement name is Arthonia polydactylonis Diederich & Ertz (≡ A. ceracea). Further new combinations are Abrothallus lobariae (Diederich & Etayo) Diederich & Ertz (≡ Phoma lobariae), A. psoromatis (Zhurb. & U. Braun) Diederich & Zhurb.

Diederich (≡ Libertiella curvispora), S. didymospora (D.Hawksw. & Miadl.) Diederich (≡ L. didymospora), Stigmidium haesitans (Nyl.) Diederich (≡ Verrucaria haesitans), and S. parvum (Henssen) Diederich (≡ Pharcidia parvum). © 2018 by The American Bryological and Lichenological Society, Inc.
