Wild Edible Mushroom

Yunnan Province, China, is famous for its abundant wild edible mushroom diversity and a rich source of the world’s wild mushroom trade markets. However, much remains unknown about the diversity of edible mushrooms, including the number of wild edible mushroom species and their distributions. In this study, we collected and analyzed 3585 mushroom samples from wild mushroom markets in 35 counties across Yunnan Province from 2010 to 2019. Among these samples, we successfully obtained the DNA barcode sequences from 2198 samples. Sequence comparisons revealed that these 2198 samples likely belonged to 159 known species in 56 different genera, 31 families, 11 orders, 2 classes, and 2 phyla. Significantly, 51.13% of these samples had sequence similarities to known species at lower than 97%, likely representing new taxa. Further phylogenetic analyses on several common mushroom groups including 1536 internal transcribed spacer (ITS) sequences suggested the existence of 20 new (cryptic) species in these groups. The extensive new and cryptic species diversity in wild mushroom markets in Yunnan calls for greater attention for the conservation and utilization of these resources. Our results on both the distinct barcode sequences and the distributions of these sequences should facilitate new mushroom species discovery and forensic authentication of high-valued mushrooms and contribute to the scientific inventory for the management of wild mushroom markets.

Wild Edible Mushroom

Purpose: The interest in evaluation of real knowledge of wild edible mushrooms at individual and population level increases mainly in developing countries. The purpose of our inquiry study was to assess the level of knowledge and awareness of the wild mushrooms in a random sample from the population of Varna region in Bulgaria. Material/Methods: We performed an anonymous questionnaire investigation of 200 adult individuals, 100 males and 100 females, from Varna region, including 17 potential opinions from their personal knowledge of wild edible mushroom usage. Statistical data processing was performed using descriptive methods, variation and correlation analyses. Results: Most respondents acquired their knowledge of wild edible mushrooms from their relatives. From all 200 persons investigated 78 respondents were not capable of recognizing at least one wild edible mushroom at all. More respondents trusted other people, who have very good experience with preparation of wild mushrooms, thus relying on differentiation of a mushroom poison. Their awareness was associated with their capacity to properly recognize wild mushrooms as well as their long-term practice to recognize toxic mushrooms. Just a minority of respondents shared that wild mushrooms in their vicinity could be a problem and had a slight idea of mycotherapy. Only two females had heard about training for wild mushroom recognition. There were statistically significant correlation dependences between respondent’s awareness of wild edible mushrooms, on one hand, and individual sex status, educational level and main residence, on the other hand. Conclusion: Our study identified two most recognized wild edible mushroom species in Varna region, edible boletus (Boletus edulis Bull) and parasol mushroom (Macrolepiota procera S. F. Gray). Most respondents acquired their knowledge of wild edible mushrooms from relatives. A problem-oriented training of the population on this topic should be performed to improve awareness of common mushroom features and avoid mushroom poisoning.

A New Species

Lactarius sect. Deliciosi includes a group of edible mushrooms with a worldwide geographical distribution. Although several species are considered choice edible mushrooms, taxonomic knowledge on this group in Asia is still fragmentary. A new species in L. sect. Deliciosi with orange latex, L. vividus, is described as an important wild edible mushroom that is widely distributed in central and southern China. Morphological analyses demonstrate that L. vividus encompasses high infraspecific morphological variation, which makes it difficult to clearly delimit its taxonomic boundary. Compared with other species having orange latex in L. sect. Deliciosi, L. vividus can be recognized by the vividly colored, subdistant to distant lamellae and heavy basidiospore ornamentation. It has been found to grow with four species of Pinus subg. Pinus including P. latteri, P. massoniana, P. taiwanensis and P. thunbergii. Phylogenetic analyses of the ITS region and glyceraldehyde-3-phophate dehydrogenase gene (gpd) support species delimitation and suggest ITS and gpd are good DNA markers to identify this new species.

Wild Edible Mushroom

Wild edible mushrooms are becoming endangered all over the world. Very few wild edible mushrooms are found in natural habitat. Volvariella bombycina is an edible and medicinal mushroom. The mushroom was collected in natural habitat growing on Populus tree. Mycelium of the mushroom was developed in PDA slant tubes by tissue culture method, incubated at 25°C for 1-2 weeks. Spawn was developed in wheat grains after incubation at 25°C for 2-3 weeks. Substrates were formulated for the development of fruiting bodies by combination of paddy straw, saw dust and rice husk. Fruiting bodies of V. bombycina was cultivated in these substrates after incubation at 28 ± 2°C for 2-4 weeks. The work describes the optimized process for in vitro culture of wild edible mushroom Volvariella bomybycina.Nepal Journal of Biotechnology. Dec. 2017 Vol. 5, No. 1: 27-31

Traditional Approaches

The tribe Meteorini includes two genera, Meteorus and Zele, which are koinobiont endoparasitoids of larval Lepidoptera and Coleoptera. More than 300 species are known, about one fifth of which occur in the Western Palearctic. Here, we revise the Western Palearctic species, based partly on traditional approaches and partly on molecular analysis of recent Swedish and Finnish material. For the analyses of phylogenetic relationships and cryptic species diversity, we coded 17 morphological characters and sequenced two markers, 28S D2 (649 bp) and CO1 (665 bp). More than 1 970 specimens representing 54 species of Meteorus Haliday and 5 species of Zele Curtis were studied; of these, 177 specimens representing 41 species were sequenced. Seven new species are described, all from the Fennoscandian material: Meteorus artocercus sp. nov., M. densipilosus sp. nov., M. eklundi sp. nov., M. longipilosus sp. nov., M. sibyllae sp. nov., M. stenomastax sp. nov., and M. subtilisulcus sp. nov. Four new synonyms are introduced: Z. chlorophthalmus (Spinola 1808), syn. nov. for M. pallidus (Nees 1812), M. punctifrons Thomson 1895, syn. nov. for M. varinervis (Tobias 1986), M. melanostictus Capron 1887, syn. nov for M. monachae (Tobias 1986), and M. tenellus Marshall 1887, syn. nov. for M. boreus (Tobias 1986). Meteorus tenellus is removed from synonymy with M. cinctellus. Sequence analysis indicated the presence of at least 12 additional cryptic species but these cannot be separated morphologically at this point and, therefore, we do not describe them here. The phylogenetic results suggest that Zele should be included within Meteorus but we refrain from formal changes of the generic classification until more comprehensive phylogenetic analyses of the tribe can be completed. A key to the known Western Palearctic species is presented.

Three New Species

Species of Diaporthe have often been reported as plant pathogens, endophytes or saprobes, commonly isolated from a wide range of plant hosts. Sixteen strains isolated from species of ten host genera in Yunnan Province, China, represented three new species of Diaporthe, D. chrysalidocarpi, D. machili and D. pometiae as well as five known species D. arecae, D. hongkongensis, D. middletonii, D. osmanthi and D. pandanicola. Morphological comparisons with known species and DNA-based phylogenies based on the analysis of a multigene (ITS, TUB, TEF, CAL and HIS) dataset support the establishment of the new species. This study reveals that a high species diversity of Diaporthe with wide host ranges occur in tropical rainforest in Yunnan Province, China.
