Marinus Anton Donk, born in pre‐Indonesia and resident during the last years of Dutch Colonial rule, fell heir to a history of mycological studies traceable to the 1600s. Rumphius, Juhnhuhn, Zollinger, von H??hnel, van Overeem, and Boedijn were some of his predecessors. He survived cruel treatment while under Japanese incarceration during World War II, to become Head of the Herbarium in Bogor (formerly Buitenzorg), Java. Indonesia. In middle age, he moved to the Rijksherbarium in the Netherlands and further established his reputation in the taxonomy and nomenclature of the Hymenomycetes, a large group of basidiomycetous fungi. He was lauded and feared by numerous mycologists before he died prematurely in 1972. Occasional contemporary (chiefly mycological) personalities are included here as well as personal Donk communications to others.
The unsatisfactory indexing of each of the three parts of Quélet’s initial mycobiota of north-east France is replaced with a single comprehensive alphabetical index to all main entries of genera, species, and varieties, with their author citations and their correct original Quélet journal references (together with their confusing page references from repaginated separata).
The Rev. Miles J. Berkeley was active in Britain in the middle of the 19 th Century. Among his many scientific endeavors was the study of fungi and plant pathology. Between 1842 and 1892 he published, alone or with collaborators CE Broome, MA Curtis, MC Cooke and JB Ellis and BM Everhart, fifty???six new species of Hypocrea and he recombined into Hypocrea two additional species. These are foundational species in the genus Hypocrea , now Trichoderma . Types of all names that Berkeley included in Hypocrea have been examined for this study. The disposition of those names is discussed. The following new combinations are proposed: Amplistroma cervinum , Ascopolyporus maculiformis , Stilbocrea neilgherriensis , Trichoderma deplanatum , T . discellum , T . grossum , T . laetioris , T . maculiforme , T . multiforme , T . petersii , T rugulosum , T . saccharinum , T . scutellaeforme , T . subrufum . Lectotypes are selected and or designated for Hypocrea farinosa , H . laetior , H . maculiformis , H . multiformis , H . neilgherriensis , H . ochroleuca , H . pezizoides , H . ravenelii , H . saccharina , H . scuellaeformis , and H . subrufa .
Four species of lichenicolous fungi (Clypeococcum epicrassum, Polycoccum cladoniae, Sphaerellothecium arnoldii, and Stigmidium aff. lecidellae) and two species o f lichenized fungi (Gyalolechia klementii and Parvoplaca servitiana) are reported for the first time from Turkey. Comments on their morphological characters, habitats, and substrates are provided, together with macro- and microphotographs.
A powdery mildew fungus appearing on the leaves of Bistorta amplexicaulis in Pakistan is described as a new species, Erysiphe bistortae . This species is characterized by its large-sized chasmothecia and relatively small conidiophores. Because of biological and morphological differences from related species, supplemented by results of molecular sequence analysis, the Asian powdery mildew on B. amplexicaulis warrants description as a species of its own.
Flavopunctelia and Punctelia species collected from Pir Panjal Ranges of Himachal Pradesh, India were studied by morphological, chemical, and phylogenetic methods. Analyses based on a concatenated ITS and LSU data set, confirmed the position of the three Indian taxa within the Parmotrema -clade in Parmeliaceae . The morphology-based taxonomic study reiterated the presence of cryptic species in Flavopunctelia with highly similar morphological characters in different species. The type species, F. flaventior, formed a well-supported monophyletic clade adjacent to F. soredica . In Punctelia , P. borreri was also established as a unique lineage along with P. perreticulata . RPB1 data were not interpreted due to data deficiency. The ITS sequence data and analyses showed Trebouxia photobionts in all the parmelioid species; that of P. borreri was identified as T. gelatinosa , but the photobionts of F. flaventior formed an exclusive clade of an apparently undescribed species of Trebouxia , and the photobiont of F. soredica formed an unresolved basal clade to the Trebouxia sp. of F. flaventior .
A new asexual ascomycete genus and species, Acropleurophialis simplex collected on dead branches of an unidentified broadleaf tree in Jiangxi Province, China, is described and illustrated. The fungus is distinguished by macronematous, unbranched, determinate or percurrently extending conidiophores, and solitary, semi-endogenous, simple, smooth, spherical or subspherical, aseptate, pale brown to subhyaline conidia seceding schizolytically from polyphialidic, integrated, terminal and intercalary, sympodial, cylindrical conidiogenous cells with conspicuous collarettes.
After final editorial review, the recently submitted ???Airborne mycotoxigenic fungi in T??rkiye and Poland??? by Giray, Zimowska, and Asan will be available for downloading from the Mycotaxon mycobiota webpage. This will bring to 157 the number of free access fungae uploaded or linked to http://www.mycotaxon.com/mycobiota/index.html
Three new anamorphic fungi, Catenularia yunnanensis , Fuscocatenula nabanhensis and F. chinensis , are described and illustrated from specimens collected on dead branches of unidentified plants in Xishuangbanna, Yunnan Province, China. Catenularia yunnanensis is characterized by its acrogenous, basocatenate, aseptate, roundedobconic, smooth conidia with 2–3 blunt corners at the distal end when viewed from above. Fuscocatenula nabanhensis is distinguished by its basocatenate, aseptate, cylindrical to slightly cuneiform, smooth conidia with protracted maturation and round outline. Fuscocatenula chinensis is denoted by its basocatenate, aseptate, obovoid, smooth conidia with round outline. The three species are described, illustrated, and compared with similar taxa. A key to species of Fuscocatenula is provided.
Comparison of the protologue of Agaricus umbellifer L. with specimens and descriptions of the basidiolichen Lichenomphalia umbellifera (L.) Redhead & al. revealed that the epithet umbellifera was misapplied to the Lichenomphalia species, causing several major conflicts with Linnaeus's species concept. A felicitous match for Linnaeus's species concept was found with a species of Marasmius sect. Epiphylli . Because A. umbellifer falls in a group that arises from an evolutionary pathway divergent from that leading to Marasmius s. str., we erected a new genus, Owingsia , to accommodate it, and recombined the type species as Owingsia umbellifera . Molecular studies demonstrated that it is a widely distributed circumpolar species, prevalent in Lapland and islands of the Baltic Sea, where Linnaeus encountered it. The earliest legitimate description of the basidiolichen L. umbellifera is A. pseudoandrosaceus Bull., a name superseded by the sanctioned later synonym, A. ericetorum Pers. We recombined this basionym as L. ericetorum , and epitypified O. umbellifera and L. ericetorum with modern sequenced specimens.
A new species of Tricholoma recorded from a temperate forest in central Serbia is described and illustrated. It is characterized by the presence of punctate, often elevated, almost black spots arranged in one to three circular zones on the pileus. The new species showed morphological differences from closely related taxa and molecular phylogenetic analysis of ITS and LSU regions confirm the distinct taxonomic status of the finding.
Based on our studies of lichen-forming fungi in Kala National Park, Northeastern Algeria, four species, C. cyathomorpha, C. dimorpha, C. monomorpha and C. subturgida, were new reported for Algeria. Descriptions and taxonomic notes are provided; and a key is presented for all the Cladonia species known from Algeria.
Seven Endophragmiella taxa were found in Thailand, from freshwater and terrestrial habitats in various locations. Five of them are proposed as new species: E. acutispora , E. filiformis , E. obpyriformis , E. sporoprolifera , and E. tunicata . Endophragmiella acutispora is characterized by fusiform to obclavate, 2–5-septate conidia; E. filiformis by obclavate, appendiculate, 3–5-septate conidia; E. obpyriformis by its obovoid or obpyriform, bicolored conidia; E. sporoprolifera by obclavate and Y-shaped, appendiculate, 5–6-septate conidia; and E. tunicata by cylindrical or oblong, tunicate, 2-septate conidia. Two other species, E. multiramosa and E. resinae, are new records for the Thailand mycota. Detailed descriptions, illustrations, and taxonomic keys comparing the new species with morphologically similar species are provided.
During routine macrofungal surveys in various temperate forests of Indian Himalayan belt, we made some collections of the interesting genus Veloporphyrellus. After through literature review, morphological examinations, and phylogenetic analysis of two ribosomal genes, those collections were found to be conspecific with Veloporphyrellus latisporus, which was described from coniferous forests of Pakistan. We present the genus and the species from India for the first time with detailed morphological description, illustrations, multigene phylogenetic analysis, and comparisons with related species.
-Four species of lichenicolous fungi (Clypeococcum epicrassum, Polycoccum cladoniae, Sphaerellothecium arnoldii, and Stigmidium aff. lecidellae) and two species o f lichenized fungi (Gyalolechia klementii and Parvoplaca servitiana) are reported for the first time from Turkey. Comments on their morphological characters, habitats, and substrates are provided, together with macro-and microphotographs.
Usnea jingdongensis from the Ailaoshan Mountain of Southwest China, is described as a new species of Parmeliaceae. It is characterized by the uninflated branches, fistulose axis with pale brown to dark brown loose hyphae, and the absence of pseudocyphellae and soralia. The phylogenetic analysis of the nrDNA ITS sequence data supported the recognition of the species. A key to the eumitrioid Usnea species in China is also provided.
Ellisembia appendiculata is described and illustrated as a new species from a specimen collected on dead branches of an unidentified broadleaf tree in Hainan Province. The fungus is characterized by distinct, unbranched conidiophores with monoblastic conidiogenous cells that produce distoseptate, obclavate or ellipsoidal conidia with 1 – 2 filiform, hyaline, aseptate, simple or branched appendages.
A new species of Termitomyces symbiotic with the termite Macrotermes natalensis is described from Africa. As there are no records of field collected basidiocarps within this lineage, traditional basidiocarp-based morphological taxonomy is not practical. While basidiocarps may be obtained rarely from incubation of fungal comb fragments, their practical use for taxonomical purposes is limited. Therefore, the species is described based on an ITS nucleotide sequence, with comparisons to an asexual culture. Based on samples with similar ITS sequences, this species is likely associated with multiple termite hosts across a large part of Africa.
Three Echinoplaca spp. are reported from China. The new species Echinoplaca infuscata is characterised by pale brown apothecia having different morphologies and colors at different growth stages, and (3–)5-septate ascospores. Echinoplaca epiphylloides and E. intercedens are reported as new from China. The macromorphology, micromorphology, secondary chemistry, ecology, and distribution ranges of these three species are presented and discussed. A key is provided to the Echinoplaca species known in China.
