(Tectariaceae) is one of the largest, morphologically diverse and more complex genera having difficulties in identifying the species and their groups. Since its description, a number of new genera had been separated from it or merged within it created considerable ambiguity. Thus, the main aim of the present review is to provide comprehensive information of the taxonomy, cytology, anatomy, palynology and molecular research carried out so far on the genus Tectaria. Present work is not merely compilation but includes personal observations and is presented here after critical evaluation.

Mahabale collected some small Isoetes from the Sahyadri Hills, India and described these as a second species that he called "Isoetes Sahyadrii " (Mahabale in Curr. Sci. 7: 62. Aug 1938). Mahabale (l.c.) depicted the species as a small plant (up to 20 cm long) with tri-lobed rhizome, without peripheral strands in the leaf, the sporangium covered by a complete velum leaving a slit-like aperture at the base, the megaspore tuberculate with uneven tubercles, etc. Although Mahabale's account of the species (l.c.) included everything needed to be perfect as a protologue for introducing a new species, he added the sentence "Accordingly it has been separated and provisionally called Isoetes Sahyadrii sp. nov." Following Art. 36.1 of the ICN (McNeill & al. in Regnum Veg. 154. 2012), Fraser-Jenkins & al. (l.c.: 57) treated this as a provisional name and hence not validly published. They also noted Rao's (l.c.) validation of the name six years later. Isoetes sahyadrii was also mistakenly cited in literature as Isoetes sahyadriensis Mahab.

The vascular cambium was differentiated, producing secondary phloem centrifugally and xylem centripetally. Phloem was composed of sieve tube members, companion cells, fibres and parenchyma, whereas the xylem was mainly thin-walled parenchyma tissue with lignified vessels embedded in it. The root vascular tissue was characterized by the occurrence of isolated, narrow, but thick-walled articulated laticiferous cells. Fusiform cambial cells produced laticiferous cells only in the centripetal direction, whereas ray cambial cells produced these cells both centripetally and centrifugally. Laticifers underwent intrusive tip growth and their maturation was marked by the disappearance of transverse septa. These cells appeared as narrow segmented cells close to the cambial zone whereas in the xylem they were isolated and elongated with sinuous or constricted walls. Radial growth, structure and distribution of laticifers in the root are discussed.

It resembles O. polyphyllum in the presence of sheathing rhizomorph and 1-4 (rarely 5) trophophylls. On the other hand, rhizomorph morphology, common stalk, trophophyll arrangement, leaf lamina and leaf base make it distinct from O. polyphyllum. Stoloniferous roots, trophophyll number and their arrangement of the new species also resemble O. parvifolium and O. nudicaule. However, both these species lack a sheath around the leaf-stem base. A comparative account of morphologically similar species, viz. O. gujaratense, O. polyphyllum, O. parvifolium and O. nudicaule is provided. The distinctness of the new taxon has been confirmed using molecular data from chloroplast genome markers viz rbcL, trnH-psbA, trnF-trnE and trnL-trnF.

The genus Sphaerobolus has fascinated several mycologists due to its unique spore-dispersal mechanism that gave it the name 'artillery fungus'. Phylogenetic analyses were carried out through the combined sequence dataset obtained using different gene loci (mtSSU, ITS, EF 1-a and LSU), which revealed the existence of four deeply divergent lineages in this genus, each distinguishing a phylogenetically distinct species. The identification key and illustration are provided based on morphology, macroscopic and microscopic morphological features to facilitate the identification of the species.

In the present study, Xylaria hypoxylon isolated from branch stubs of living trees was utilised for in vitro decay test to investigate the pattern of cell wall alterations in sound wood blocks of Azadirachta indica, Leucaena leucocephala, and Tectona grandis. Naturally infected as well as in vitro decayed wood showed cavities and erosion troughs at the lumen surface. In laboratory decay test, vertical invasion of mycelia occurred through the lateral wall pits of the vessels and vessel-associated parenchyma while ray cells enabled radial movement of mycelia. At the end of 60 days, the progression of degradation in the fibre cell wall was evident by the formation of transverse boreholes in the cell walls, erosion troughs at the lumen surface, and larger cavities in the S2 layer of secondary wall. The erosion channels were angular to round (i.e. V-shaped or U-shaped). Fungus was also tested for polyphenol oxidase (Bavandemm’s test) production by on-plate assay and was found to be positive. Confocal microscopy revealed delignification pattern during degradation of cell wall of different cell types in all the three woody species. The SEM analysis of degraded wood showed the ultrastructural changes in the cell wall particularly penetration of hyphae through the S2 layer of the cell walls forming tunnels through it.

Therefore,to overcome this problem and its mitigation is always been serious and important issue worldwide.Application of microbial enzymes to remediate these recalcitrant compounds fromthe environment is very well-known biological solution, which is effective since last few decades. Present study deals with application of ligninolytic enzymes produced by a wild strain of Phanerochaete chrysosporium to degrade four reactive textile dyesviz. Reactive Red HE8B, Reactive Black B, Reactive Golden Yellow HR, and Reactive Violet 5R. The fungus was obtained from the decaying wood log of the tree growing Junagadh Forest of Gujarat State.It is not only proved to be potential strain in decolourisation of dyes but also proficiently degraded all the dyes under solid and liquid decolourisation media. The decolourisation and degradation study was efficiently supported by the FTIR analysis of dyes treated with ligninolytic enzymes produced by solid state fermentation.On plate ddecolourisation of dyes initiated after three days of fungal inoculation and the petri plates with 10 mg/L concentration of all four dyes were completely decolourised within 11 days, except Reactive Red HE8B which took 13 days after incubation. Supplementation of different sources of carbon and nitrogen influenced the process of decolourisation, in which dextrose and asparagines were found to be excellent supporters respectively.Interestingly one of the nitrogen sources i.e. sodium nitrite inhibited growth of the fungus.Influence of inoculum size on decolourisation was performed with different inocula size on solid and in liquid media, where one to three discs (10mm diameter agar plugs) were reported to be more effective in the rate of the decolourisation.

It is well known in Ayurvedic medicine and locally called Tambadivasu. Superficially it is similar to other species of Boerhaavia and species of Trianthema and Sesuvium. Due to the minute morphological differences, the above plants are erroneously used in medicine as Punarnava, and at times on purpose as an adulterant. Therefore, it is necessary to highlight the anatomical features of Punarnava for proper identification of the medicinal plant species for local people and for scientific research. Due to the ambiguity in local names and similar apparent appearance, market samples of Punarnava are often adulterated with various species of Trianthema and Sesuvium. These adulterated samples contain neither the Punarnavine alkaloid, nor does it possess anisocytic stomata but possess paracytic stomata. Comparative study of stem anatomy showed two main characteristic differences. First, plenty of starch grains can be seen in both the ground parenchymatous tissues present in between successive cambia and xylem parenchyma of Punarnava which is not observed in species of Trianthema, and second, the phloem around the xylem of Punarnava root has semi-circular or eccentric patches, while that of Trianthema only has narrow strips. This study is focused on comparative SEM study of leaf morphologies and anatomy of leaf, stem, and root of Boerhaavia diffusa L., Trianthema portulacastrum L. and Sesuvium portulacastrum L.

Gujarat is known for its varying climates starting from moist deciduous forest (south Gujarat, a part of Western Ghat) to pure desert conditions (Great Rann of Kuchh). In spite of this, taxonomic exploration was carried out for the first time. The present study we reports 46 species from which four species are reported previously while rest of the 38 species are documented for the first time for the state. Highest numbers of species (39) are found in Agaricus while Macrolepiota, Cystoagaricus and Podaxis have single species each. Maximum diversity is observed in the districts like Dangs, Ahawa, Navsari, Narmada, Junagadh and Chhotaudepur while minimal diversity is observed in Rajkot, Kutchh and North Gujarat (Palanpur, Banaskantha, Sabarkantha). Among them Agaricus bisporus, A. blazei, A. campestris, Chlorophyllum molybdites, Coprinellus micaceus, Cystoagaricus trisulphuratus, Leucoagaricus rubrotinctus, Leucocoprinus brebissonii, Podaxis pistillaris are common while Macrolepiota procera is collected only from one locality. We expect much more species in Agaricaceae than reported in the present study and we suggest further studies to understand the diversity of Agaricaeae in the state.

The in vitro decay test was conducted for 12 weeks. Both species of Trametes used in this study caused anatomical characteristics specific to simultaneous white rot. Formation of boreholes, erosion troughs, erosion channels with U-shaped notches in tangential sections and thinning of cell walls were evident in the wood inoculated with each of the fungal species. Cell separation due to removal of middle lamellae occurred at the early stages of infection (30 d) with T. versicolor. In contrast, middle lamellae remained intact in wood inoculated with T. hirsuta and showed cell separation due to degradation of the outer layer of the secondary wall and degradation of the middle lamellae observed only in severely decayed wood at late stages. Confocal microscopy revealed the delignification pattern particularly from cell corners and vessel walls at an advanced stage of decay, indicating strong ligninolytic activity of both species in the sapwood of L. leucocephala.
