The identification of Auricularia species has previously relied on the examination of macroscopic features of mushroom samples collected in Thailand. These features may vary with age, light exposure, moisture and other factors, making such identification prone to error. This study uses morphological characteristics and molecular data to improve upon previous classifications of Auricularia species. Fruiting bodies collected during recent field excursions and previous collections from herbaria were examined and sequenced for two loci, viz. ITS and rpb2. Auricularia asiatica is described as a new species based on both morphological characteristics and molecular data, and is introduced with a full description, illustrations and colour photographs. Auricularia cornea and A. villosula are described as new records from Thailand. A combined ITS and rpb2 phylogenetic tree is provided, showing the placement of five Auricularia species found in Thailand.

A new species, Calocybe decurrens, is illustrated and described in detail based on morphological characteristics and phylogenetic analyses. Calocybe decurrens is mainly characterized by its decurrent gills and by its stipe that discolors upon maturation. Molecular phylogenetic analyses were based on the internal transcribed spacer (ITS1-5.8S-ITS2) and the large subunit of the nuclear ribosomal DNA (nrLSU) sequences. The results indicated that its affiliation is in genus Calocybe, where it occupies an isolated position. A full description, color images, illustrations and a phylogenetic tree to show the placement of the new species are provided.

During an investigation into the microfungi on Dracaena fragrans in Thailand, a saprobic taxon belonging to Glomerellaceae was collected. Based on morphological characterization and combined phylogenetic analyses of ITS, GAPDH, CHS-1, ACT and TUB2 sequence data from the sexual and asexual morphs our taxon was identified as a new species of Colletotrichum. Colletotrichum dracaenigenum sp. nov. is introduced here with a full description, colour photographs of morphological characteristics and a phylogenetic tree to show the placement of the new taxon in the gloeosporioides species complex.

Leptochelia Vatulelensis(Crustacea: Tanaidacea), A New Species From Anchialine Caves of the South-Western PacificLeptochelia vatulelensisn. sp., discovered on the small islands of Vatulele (Fijian group) and Ouvéa (Loyalty Islands, New Caledonia), is described and illustrated. The new species is distinguished from the others of the"Leptochelia-dubiagroup" (to which it is generally similar) by the following combination of morphological characteristics: (1) the presence of three to four distal setae on the maxilliped basis; (2) merus of pereopods III and IV with only a distosternal seta; (3) endopod of the uropods formed of four (rarely three) articles; (4) males with two (sometimes three) relatively short aesthetascs on the first five articles of the antennular flagellum; (5) male cheliped with a diminished dimorphism; (6) males with a vertical comb-row of setae on the cheliped propodus. Although it inhabits inland, anchialine caves, the new species lacks morphological features that are characteristic of some cave species.

During our surveys of fungi of some areas adjacent to the Cholistan desert, Punjab, Pakistan, we collected a new species in Lepiota sect. Echinatae. It was found on loamy soil under Vachellia nilotica and is described and illustrated as new based on the distinct morphology and ITS nrDNA analysis. The new species, Lepiota haroonabadensis, is characterized macroscopically by a light yellowish orange pileus covered with brown squarrose scales, bright yellowish to yellowish red stipe with pale yellow spiny scales, and rudimentary annulus; and microscopically by ellipsoid basidiospores, narrowly clavate to clavate cheilocystidia, cylindrical to sub-cylindrical or ellipsoidal elements of the pileus covering and cylindrical to globose elements of the stipe covering. A full description, color photos, line illustrations and a phylogenetic tree to show the position of the new species are provided.

In May 2020, a new taxon of Euphorbia, Euphorbiaceae was collected from a dry hillside of Dongsheng District, Ordos City, Inner Mongolia. The morphological characteristics of the specimens analyzed differ from those of the known Euphorbia species from this region; therefore, we suspected this may be a new species, and we set to analyze the ITS2 sequences of some Euphorbia species. The results show that the new taxon belongs to the sect. Esula of Euphorbia subg. Esula. It is similar to Euphorbia esula (description from Flora of China) but does not belong to the same species. Concomitantly, plant morphological data and pollen morphology results show significant differences between the new taxon, E. esula and E. caesia, a finding that supports the delimitation of this new taxon, which is named Euphorbia mongoliensis in accordance with its geographical distribution.

Prosopanche cocuccii is described as a new species from Southern Brazil. It resembles P. bonacinae due to the trigonous rhizome and by the general size of the flower organs. Nevertheless, P. cocuccii is distinguished by the main floral morphological characteristics used to differentiate species. In addition, the new species presents some rare characters for the genus, such as a highly branched rhizome and flowers usually grouped in fascicles. We provide a description, illustrations, field photographs, morphological details under the stereomicroscope, and comments on habitat, ecology, distribution, and conservation of the new species, as well as an updated key for the genus Prosopanche. In addition, we identified that P. cocuccii produces a large number of rhizomes and fruits for each single host specimen of tobacco (Nicotiana tabacum), which resulted in a decrease in height and growth of its only known host plant.

Macroinvertebrate samples collected during spring-summer 2013 in high mountain rivers of the Ordesa and Monte Perdido National Park (Pyrenees) contained several Hydraena species (Coleoptera: Hydraenidae) where we found two genera of suctorian ciliates as epibionts: Tokophrya and Discophrya. The individuals of the genus Tokophrya probably belong to species Tokophrya stenostyla, being the first time that this species is observed attached on arthropods. Suctorians of the genus Discophrya were identified as a new species called Discophrya ordesae sp. n. The presence and abundance of epibionts was discussed in the frame of the biological and ecological characteristics of the species of Hydraena where they were found.

All known bird fleas are believed to have been derived from species that originally infested mammals. Circumstances evidently have occurred whereby representatives of species that were ordinarily the parasites of mammals became associated with buds, and were successful in establishing themselves on these hosts. These circumstances must have included some provision for isolation whereby the newly transferred colonies of fleas were not given the opportunity of becoming reassociated with the original hosts, and also were not contaminated by subsequent introductions of others of their species. Thus they were able to become adapted to an existence on the bodies and in the nests of avian hosts. The adaptations were physical as well as physiological, many bird fleas exhibiting morphological characteristics which, though not yet properly understood, apparently bear some relationship to their specialized environment.
