Two new species of Russula are described and illustrated in this paper. Russula clavulus is recognised by a pale yellow pileus centre, white margin with tuberculate striation, white to pale lamellae with small pale yellow spots, white to light yellow spore print, subglobose to broadly ellipsoid spores with short or long ridges and hymenial cystidia on lamellae sides that are mainly subclavate or fusiform. Russula multilamellula is morphologically characterised by the brownish orange to hazel pileus centre and satin white to yellowish-white margin with brownish tinge, lamellulae that are usually irregular in length and often anastomosing with lamellae, subglobose to broadly ellipsoid spores with short or long ridges and clavate hymenial cystidia. The combination of morphological features and multigene phylogenetic analyses of ITS-nrLSU-RPB2-mtSSU data indicated that these two new taxa belong to Russula subg. Heterophyllidia sect. Ingratae.

A couple of forays to the temperate to subalpine regions of the western Himalaya uncovered two new species: Russula rajendrae and R. petersenii. Russula rajendrae (subg. Russula sec. Russula subsect. Russula), is characterized by a pale red to venetian pink or pastel red colored pileus with grayish yellow patches in the center, a white spore print, an acrid taste, and cystidia with variably shaped apices (capitate, rounded, moniliform, appendiculate or pointed) whereas, Russula petersenii (subg. Russula sec. Paraincrustatae subsect. Integrae), is characterized by a white pileus with pale yellow to light yellow patches and a concolorous stipe, white to yellowish white lamellae with 3 series of lamellulae, a white spore print, an acrid taste, basidiospores with isolated warts (sparsely connected in places), and different types of cystidial apices. Macro- and micromorphological descriptions together with illustrations and phylogenetic inferences are presented for both species. Allied taxa (endemic and extralimital) are also compared.

Molecular Trees

In China, the European species, Hygrophorus chrysodon, is widely reported in western and northeastern provinces. After carefully comparing H. chrysodon from China and Europe, we found that the European and Chinese materials were different lineages in molecular trees, and there were also obvious differences in morphology between the two lineages. The evidence from morphology and phylogeny indicated that the presence of H. chrysodon in China is doubtful and that the Chinese material represents an undescribed species. Thus, H. aurantiosquamosus is proposed as a new species. This new taxon is characterized by its yellowish white pileus covered with golden yellow squamules, a stipe concolorous with the pileus and covered with yellow floccules, a distinct pileipellis composed of narrow hyphae with inflated terminal elements of various shapes (clavate, cylindrical, lacrymoid to subglobose), and elongate to subcylindrical basidiospores measuring 9.5–12 × 4–5.5 μm. The new species occurs in Picea forests at high elevations of western China, such as Qinghai, Sichuan, and Tibet provinces.

A new species, Ptilagrostis arcuata, from Qinghai-Tibet Plateau is described and illustrated. It is easily distinguished from the similar P. concinna by its arcuate or heliciform awns with golden yellow or pale yellow hairs, narrower basal leaves, and absence of bracts below the panicles. The chromosome number of the new species is 2n=22, karyotype 2n=22=14m+6sm+2st.

At the middle of the wing at base in a narrow denuded space, and the internal angle is also devoid of scales, but much more narrowly so than in denudata. The transparent space is golden yellow in shade. Lower wings transparent golden yellow, with very bright but dark opalescent reflection. The margin and spot at the extremity of cell dark brown. Antennæ bluish black, orange brown at the base. Head, disk of thorax, and the upper portion of the abdominal segements, black. Eyes black, palpi with black at their base.

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.

Aim: To find out the optimum harvesting stage of high yielding rapeseed-mustard varieties to fit in rice based cropping pattern. Study Design: The field study was arranged following RCB (factorial) design with three replications. Place and Duration of the Study: Agronomy field of Regional Agricultural Research Station, Jamalpur (located between 24°34ʹ and 25°26ʹ North latitude and 89°40ʹ and 90°12ʹ East longitude), Bangladesh during 2015-2016 and 2016-2017. Methodology: Seeds of mustard varieties viz. BARI Sarisha-11, BARI Sarisha-14, BARI Sarisha-15, Binasarisha-4 & Tori-7 were sown in line maintaining 30cm spacing on 02 November, 2015 and 06 November, 2016. This varieties were harvested at four different harvesting stages viz. H1= Green stage of siliquae, H2= Pale yellow stage of siliquae, H3= Golden yellow stage of siliquae and H4= Full maturity stage of siliquae. Green stage of siliquae was determined just at seven to ten days after all flower droppings of crop while the pale and golden yellow stage of siliquae was determined when 40%-50% and 70%-80% bearing turned into light yellow and deep yellow in color respectively. Full maturity stage of siliqua was determined when lower bearing just brust out. Results: BARI Sarisha-14, BARI Sarisha-15 (B. campestris) and Binasarisha 4 (B. napus) may be harvested at pale yellow stage of siliquae at 73, 82 and 78 DAS (average of two years) considering 11.0% seed and 3.15% oil yield; 10.0% seed and 1.56% oil yield; 6.60% seed and 3.90% oil yield loss respectively than full maturity stage of siliquae. Conclusion: BARI Sarisha-14, BARI Sarisha-15 and Binasarisha 4 need to be sown within first week of November in districts named Mymensingh (located 24°15′ and 25°15′ N and 90°49′ E longitudes),  Jamalpur (located 24°34ʹ and 25°26ʹN latitude and 89°40ʹ and 90°12ʹ E longitude) and Tangail (located 24°01′ and 24°47′ N latitudes and 89°44′ and 90°18' E longitudes) and the crop should be harvested at pale yellow stage of siliquae (within 73-82 days period) sacrificing seed and oil yield loss to some extent to introduce HYVs of rapeseed-mustard in rice based cropping pattern.
