ABSTRACT The present paper deals with the eleven species germplasm of Xylariales collected from forest of Gujarat, India. An intensive survey in Gujarat was carried out from 2007–2015. From the total collection 11 xylariaceous fungi were identified in which six belong to daldinia four belong to xylaria and one belong to hypoxylon of Xylariaceae. Daldinia bambusicola Y.-M. Ju, J. D. Rogers, & San Martín, Daldinia loculata (Lév.) Sacc., Daldinia petriniae Y.-M. Ju, J. D. Rogers, & San Martín, are new records to Gujarat. Although some of these species have been previously recorded, present collections showed remarkable morphological differences to the previously described ones.

1. INTRODUCTION

Although conservative estimate of fungal species worldwide ranges from 1.5 to 5.1 million, currently accepted number of fungi ranges between 0.5 and 3 million [1,2]. According to The Dictionary of the Fungi and Index of Fungi, from 1943 and 2008, on an average 950 species in 73 genera of fungi have been introduced. The number of ascomycetes World Scientific News 66 (2017) 43-55

as a percentage of known fungi has almost doubled during this period [3]. India is one of the mega biodiversity countries in the tropics with a very notable diverse fungal population. Ascomycotina is the largest subdivision of the fungi encompassing 2700 genera and 28,500 species. Based on the published literature, it is estimated that the Ascomycetes form approximately 40 to 45% of the total fungi and this proportion is also true for Indian records [4]. The xylariaceous fungi of the tropics are diverse and colonize several substrata such as dung, ant and termite nests and decayed plant materials; these are phytopathogens and endophytes [5]. A general account of the family Xylariaceae has been more or less neglected in India and whatever is known, is found in scattered reports by different workers [6-10]. Several monographs, reports, field manuals and pictorial handbooks are available for xylariaceous fungi identification. On the contrary, no such information is available on the fungal diversity of Gujarat state of India. A few sporadic reports on the occurrence of new species, fungal pathogens of agricultural crops, timber decaying fungi, lignicolous fungi were published by earlier workers [11-14]. In the present study we attempted to document the diversity of Xylariaceae, which is a rich source of various secondary metabolites due to endophytic nature of many species [15-17]. It is also valued for various lignocellulosic enzymes that have a wide application in pharmaceutical, paper and pulp industry, in textile industry etc. [18]. Beneficiary to the record, the present study contributes 19 species of Xylariaceae belonging to three genera viz. Daldinia (3 species), Hypoxylon (2 species) and Xylaria (14 species) [19]. Due to lack of information and studies on fungal diversity of the Gujarat state, it is difficult to establish the exact number of species in all three mentioned genera of Xylariaceae and their distribution in the state. The main aim of the present study is to document the diversity status of Xylariaceae from the Gujarat state (India).

2. MATERIALS AND METHODS Study area Gujarat is bounded by the Arabian Sea at the southwest and geographically located between 20° 6' N t° 24° 42' N and 68° 10'E to 74° 28' E. The total geographical area of the state comprises of land mass of 1,96,204 km2 (75,755 sq miles) from which a little or less than 20 lakh hector of land is under forest cover which is unevenly distributed but the major concentration is found on the eastern hilly Saurashtra region. The temperature of the state ranges from 1 °C to 46 °C. The high variation in geophysical and climatic conditions resulted in the formation of different forest types. The rainfall received in the state varies from region to region and the northern part of the state is a desert.

Identification of fungi Extensive fieldwork was carried out in different forest regions with various climatic regimes like moist deciduous forest, dry deciduous forest, scrub forest, wet lands, arid and semi-arid regions of the Gujarat state during 2007 to 2015. Fresh specimens were collected during monsoon and the fruiting bodies of all the fungal strains were kept in the sterile polyethylene bags from different locations and brought to the laboratory. The transverse sections of stromata were mounted in lactophenol as well as stained with iodine reagent to study characteristics of perithecia, asci and ascosopres. 5-10 % potassium hydroxide is useful for softening the fungal tissue. After clearing, the KOH can be washed off with water using a

-44- World Scientific News 66 (2017) 43-55

dropper or pipette and replaced with stain. All specimens were examined for their morphological characters and identified with the help of available literature [6-10,20-29].

3. RESULTS

An intensive survey in Gujarat including hilly regions, plains of different climatic regimes and agricultural lands was carried out from 2007–2015. From the total collection 11 xylariaceous fungi were identified in which six belong to daldinia four belong to xylaria and one belong to hypoxylon of Xylariaceae. The detail morphological characteristics are:

4, DISCUSSION AND CONCLUSIONS

State of Gujarat is never explored for the fungal diversity. Available literature indicates that most of the studies on fungal diversity of Gujarat state are from plant of forest areas, sawmills, timber depose [12-14]. For the first time fungal diversity of timber degrading fungi was studied in Gujarat, India. The Xylariaceae members like Daldinia concentrica (Bolton) Cesati and de Notaris, D. sacchari Dargan & Thind, Hypoxylon rubignosa Pers. ex. Fr., Xylaria feejeensis (Berk.) Fr., X. polymorpha (Pers.) Grev. and X. allantoidea (Berk.) Fr. Were reported by Nagadesi and Arya [12]. The commonly observed timber decaying fungi belonging to Ascomycota was Daldinia concentrica and Xylaria polymorpha [12]. New records of Lignicolous fungi from Ratanmahal Wildlife Sanctuary, Gujarat, India were

-49- World Scientific News 66 (2017) 43-55

studied by Nagadesi and Arya [13] and reported Daldinia concentrica, Hypoxylon rubiginosum Xylaria polymorpha from forest area of panchmahal [13]. Wood Decay Fungi Associated with Tamarind tree in Gujarat, India was Daldinia concentrica causes Canker rot, and Xylaria polymorpha causes soft rot [14]. In present paper 3 Daldinia fungi were described newly. Daldinia childiae, Hypoxylon rickii, Xylaria apiculata, X. carpophila, X. cubensis, X. filiformis, X. gigentea, X. hypoxylon, X. longipes, X. nigripes, X. primorskensis and X. psidii are new fungal record to Gujarat [19]. In present paper Daldinia bambusicola Y.-M. Ju, J. D. Rogers, & San Martín, Daldinia loculata (Lév.) Sacc., Daldinia petriniae Y.-M. Ju, J. D. Rogers, & San Martín, are new records to Gujarat. More species are expected from the family and therefore; further studies are wanted to investigate the diversity of fungi occurring within the state.
