The Japanese mycologist, Yosio Kobayasi, described 16 species of Japanese Dacrymycetes. Almost all of the type specimens were thought to have been destroyed during World War II. In this study, Kobayasi's specimens were surveyed, and holotypes of six species, Dacrymyces adpressus Kobayasi, D. applanatus, D. pezizoides, D. puniceus, D. subalpinus, an...

COVID-19 pandemic is described as the most challenging crisis that humans have faced since World War II. From December 2019 until August 2021 based on the dataset provided by WHO, globally 219 countries in the world are affected by this virus. There are 205.338.159 cases cumulative total and 4.333.094 death cumulative total caused by this virus. In...
Development of quartz industry in these 100 years, in the synthetic production and in application of quartz crystals, is surveyed briefly. Due to the discovery of piezoelectricity in 1880 by J. & P. Curie, the invention of a quartz resonator in 1921 by W. G. Cady, etc., it had been shown that quartz crystal can be used as a superior device material...
We use data from the adult cohort of the National Education Panel Study to analyse the changes in the employment histories of cohorts born after World War II and the role of atypical employment in this context. Younger cohorts are characterised by acquiring more education, by entering into employment at a higher age, and by experiencing atypical em...
Backscatter communications, which originated from World War II, have been widely applied in the logistics domain, and recently attract emerging interest from both academic and industrial circles. Here, the backscatter communication systems equipped with retrodirective arrays that can re‐transmit the impinging signals back toward the direction of in...

... They are Dacrymyces san-augustinii with multiseptate basidiospores and stipitate-cupulate Dacryopinax elegans, both with simple hyphal septa. The type of Da. san-augustinii could not be traced either for earlier revision (McNabb 1973), or in a recent study of species described by Y. Kobayasi (Shirouzu & Hosoya 2017). This species' treatments are in discordance between authors: Shirouzu et al. (2009) mentioned 7-septate basidiospores in a material from Japan, while McNabb (1973) referred to 12-septate ones from a Hong Kong specimen, and Olive (1958) cited 13-septate spores in a specimen from Tahiti. ...
The genus Dendrodacrys is a monophyletic group that belongs to Dacrymycetes (Agaricomycotina, Basidiomycota) and accommodates species distinguished by strongly branched hyphidia in combination with 3-septate basidiospores. While the original circumscription mainly treated European taxa, here we shift the focus to tropical and sub-tropical material and uncover wider variation in morphology within Dendrodacrys. Still united by hyphidia shape and basidiospore septation, the genus is expanded with 10 taxa having pustulate, cerebriform, or stipitate basidiocarps of yellow to dark brown colours, cylindrical to ovoid basidiospores, and hyphal septa with or without clamps. Monophyly of the amended Dendrodacrys is confirmed with a phylogeny based on six markers (SSU, ITS, LSU, TEF1-α, RPB1, and RPB2). As a result, we describe two new species (De. laetum and De. rigoratum), transfer three existing species to Dendrodacrys (De. brasiliense, De. dendrocalami, and De. pezizoideum), and raise one variety to the species level (De. kennedyae ≡ Dacrymyces enatus var. macrosporus). In addition, we provide descriptions for the earlier combined De. paraphysatum and four new informal taxa. Lastly, we present illustrations, a character table, and an identification key that addresses all known dacrymycetes with branched hyphidia.

... Since specimen information in the mycological herbarium of the National Museum of Nature and Science where both authors work (TNS, Tsukuba, Ibaraki, Japan) has been databased in the last 15 years, some type specimens collected in Japan that had been believed lost were discovered in TNS (Shirouzu & Hosoya 2017). As a result of searching 'Lachnum japonicum' in the TNS herbarium database, one specimen record TNS-F-209717 was discovered and we checked the corresponding specimen was surely stored in the designated shelf. ...
Type specimen of Lachnum japonicum Syd. & P. Syd. was discovered in the National Museum of Nature and Science (TNS). Based on the morphological reexamination of it, the species was transferred to the genus Trichopezizella. Trichopezizella japonica comb. nov. was proposed and the specimen was designated as lectotype.
... Dacrymyces pezizoides Kobayasi (1939: 126), a jelly fungus of the wood-decomposing Dacrymycetaceae (Dacrymycetes, Agaricomycotina, Basidiomycota), was found in Izu Peninsula, Japan in 1933 and described as a new species by Kobayasi (1939). This dacrymycetous species is characterized by orange turbinate or irregularly discoid basidiocarps, hyphae without clamp connections, thick-walled marginal hyphae, and 3-septate basidiospores (Kobayasi 1939;Shirouzu & Hosoya 2017). ...

Dacrymyces pezizoides has been rediscovered for the first time since its original description in 1939. Dacrymycetous fruiting bodies recently collected from the dead branches of broad-leaved trees in Japan were identified as D. pezizoides based on
their morphological characteristics, i.e., turbinate or discoid basidiocarps, hyphae without clamp connections, thick-walled marginal hyphae, and 3-septate basidiospores. Molecular phylogenetic analysis based on the LSU nrDNA and ITS regions revealed that D. pezizoides forms a clade with other Dacrymyces spp., such as D. stillatus and D. chrysospermus, and Guepiniopsis buccina. Dacrymyces pezizoides is considered to form basidiocarps in autumn on the dead branches of broad-leaved trees in warm-temperate areas of Japan.
