INTRODUCTION
Biodiversity or biological diversity refers to the variety
of life forms and habitats found in a defined area. The
existence of biological diversity on this planet is due to
the evolution and co-evolution of different types of life
form, habitats and culture or it may be the result of
evolutionary plasticity of living forms present on this
planet. Every organism resent on earth plays its
significant role, harms and benefits each other in some
way or the other, in order to study its significance it must
be explored. In over-all reviews of biodiversity and
global genetic resources, micro-organisms in general and
fungi in particular did not receive attention they deserve
on account of their abundance and extend to which they
can be exploited commercially (Cronke et al., 1988;
Wolf, 1987) . Fungi is the most important group of
organisms without these the earth would be heaps of
garbage as these organisms plays important role in
decomposition of dead organic matter. Fungi are also
source of important antibiotics that can save the lives of
human. For example, Penicillin it is difficult to
comprehend that how many lives have been saved by this
particular antibiotic during the World War II.
The tremendous discrepancy between the numbers of
known verses estimated species appears to relate to the
fact that there has been woefully inadequate sampling of
fungi in many parts of the world, most notably tropical
and subtropical regions. This is the need of an hour to
explore the unexplored populations of world’s fungi.
One third of the fungal diversity exists in India. Out of
1.5 million fungi, only 50% are characterized until now.
These fungi need to be characterized because of their
high medicinal value and beneficial for human beings; its
importance is increasing day by day. They also exhibit
great degree of biodiversity with respect to aquatic
environment. But the assessment of aquatic fungal
biodiversity is still not complete.
MATERIALS AND METHODS
Collection: Water samples along with decaying leaves,
roots, twigs from different lotic water bodies of
Pachmarhi was collected. Foam, scum samples were also
collected with the help of plastic cup or spoon, spores
being lighter get trapped in foam and scum samples.
Temperature and pH were recorded and dissolved
oxygen was fixed on the spot.
Isolation: Isolation of fungi was done through various
techniques, Viz., baiting technique, aerated water
technique. In this method water samples were placed in
pre-sterilized petriplates and baits were added to provide
nourishment for the growth of fungal forms. In each
petridish pinch of antibiotic was added to prevent
bacterial contamination. After couple of days of
incubation, baits infected with fungi are observed under
the compound microscope.
Identification: The camera lucida drawings along with
measurement were made from freshly isolated fungal

ABSTRACT
Taxonomy of aquatic fungi is the most ignored field or very little work in that particular field has been done
especially in India. Pachmarhi is the biosphere reserve and hill station of Madhya Pradesh and is totally virgin
with respect to taxonomy of aquatic fungi. To explore the aquatic fungi from lotic water bodies of Pachmarhi
efforts was made by authors and during the study period aquatic fungi belong to different groups and orders has
been isolated. A total of 10 species has been isolated and identified belong to order Moniliales and Blastocladiales
during the study period of Aug 2014 to July 2015. Physico-chemical factors have also been studied in order to see
the effect of these physico-chemical factors on the occurrence and activity of these fungi.
KEY WORDS: New reports, Aquatic fungi, Pachmarhi, Lotic water, Physico-chemical factors.

forms and prepared slides. Identification of aquatic fungi
was done with the help of manuals, monographs and
published work of some eminent scientists like Ingold
(1942, 1975a). Ellis (1971, 1976), Webster and Descals
(1981), Barnett and Hunter (1972), Coker and Mathews
(1937), Sparrow (1942, 1960), Johnson (1956), Khulbe
(2001), Karling (1977.)
Preservation: Preservation of fungal forms was done
with F.A.A. 1:1:1 Ratio.
OBSERVATION, RESULTS AND DISCUSSION
A total of 118 isolations were made which belong to 6
genera and 10 species. Of these, 6 species belong to
Deuteromycotina order Moniliales and 4 species belong
to Mastigomycotina order Blastocladiales.

DISCUSSION
Temperature the most significant and essential factor that
directly affects the growth, distribution and development
of fungal community in nature (Mishra, 1982;
Suberkropp, 1984; Iqbal and Webster. 1973a) totally
agrees with the present investigation. Fungal diversity
shows inverse relation with temperature. During winters
fungal diversity was found to be high as compared to
monsoon and summer. Table 5 and Figure 1 and 9.
In chemistry, pH (potential of hydrogen) is a numeric
scale used to specify the acidity or basicity of an aqueous
solution. The pH value ranges from 6.2 to 8.2 in the
alkaline range. pH shows variations during different
seasons thus with other factors it can affect the fungal
diversity. Table 5 Figure 2 and 9.
Calcium and Magnesium hardness was found to be high
during winters corresponding to the number of fungal
species. In monsoon the calcium and Magnesium was
found to be lower than summer but fungal diversity was
found to be high as compared to summer. Dayal and
Tandon (1962) and Mishra (1982) did not find any
significant correlation between total hardness and fungal
diversity agrees with the present investigation. Table 6
and Figure 3,4 and 9.
Dissolve oxygen is found one of the significant
parameter as it regulates the metabolic process of the
aquatic organisms. Their diversity may be determined
with the dynamic and distribution of oxygen. Dissolved
oxygen and fungal diversity was found to be high during
winters as compared to the monsoon and summer. Thus
from the table 7 and figure 5 and 9 it can be concluded
that oxygen plays direct in growth and activity of fungal
diversity thus is a significant factor. BOD content was
found to high during winters corresponding to the
number of fungal species. During monsoon it shows
moderate value and fungal diversity was found to be
moderate and in summer both BOD and fungal diversity
was found to be low. The survey of available literature
reveals that there has been no work on the diversity of
fungi in relation to BOD. Table 7 and Figure 6 and 9.

Table 8 and Figure 7 and 9 show that in the present
course of study during monsoon, carbonate alkalinity
was present in very low quantity. It gradually increases
in winter and maximum recorded in summer. In summer
fungal diversity was found to be low while in winter its
values are moderate but the fungal diversity was found to
be high. Bicarbonates show maximum value than
carbonates. Bicarbonates were high during the winter
when fungal diversity was found to be high. In summer
bicarbonates shows moderate values but the fungal
diversity was found to be low. At all sampling sites
alkalinity was comparatively higher in winter than other
seasons due to presence of carbonates and bicarbonates,
when maximum fungal occurrence was recorded. Table 8
and Figure 8 and 9.

CONCLUSION
Very little work is being done on Taxonomy of aquatic
fungi particularly in India therefore the authors tried to
explore some aquatic fungi from the Pachmarhi
Biosphere Reserve Madhya Pradesh first time and
reported total 10 species of fungi belonging to the
Moniliales, Blastocladiales. From this study we are
concluding that there are large numbers of fungi which
are yet to be explored from many places particularly in
India.
As the Fungal diversity is fundamental to the success of
biotechnology and is critical if the commercial potential
of fungi is to be fully realized. So it is very important to
study the taxonomy of this kingdom.

Article
Sixty-four species of aquatic Phycomycetes are reported from Mississippi. Of these, 54 species are recorded for the first time from this state.
Article
An account is given of a flora of submerged aquatic Hyphomycetes growing on decaying leaves of alder and willow in a stream. The flora consists of sixteen species belonging to thirteen genera. The majority of these fungi produce conidia which are branched, and in most of these species the conidium consists of four divergent arms. In three species, belonging to different genera, an elongated spore with a three-dimensional curvature is produced. Only in one species is the spore more or less spherical.The following fungi, already known to science, are members of the flora: Lemonniera aquatica De Wild., Clavariopsis aquatica De Wild., Varicosporium Elodeae Kegel, and Tetracladium Marchalianum De Wild., although a more restricted definition is proposed for the last species. Tridentaria setigera Grove is reported, but it is suggested that this species should be removed to the genus Tetracladium and the binomial T. setigerum (Grove) n.comb. is suggested. The relationship between the genera Titaea and Tetracladium is discussed, and it is pointed out that Titaea maxilliformis Rostr. should be regarded as a species of Tetracladium. Of the three species with elongated spores the only one which seems to be referable to a known species is Fusarium longissimum Sacc. & Syd. (=F. elongatum De Wild.). It is pointed out that this species cannot be regarded as belonging to Fusarium, and the name Anguillospora longissima (Sacc. & Syd.) n.comb., is proposed.The remaining ten species belonging to seven genera appear to be new to science. These are as follows: Margaritispora aquatica, n.gen., n.sp., Articulospora tetracladia n.gen., n.sp., Tetrachaetum elegans n.gen., n.sp., Tricladium splendens n.gen., n.sp., T. angulatum n.sp., Heliscus aquaticus n.sp., H. longibrachiatus n.sp., Alatospora acuminata n.gen., n.sp., Lunulospora curvula n.gen., n.sp., and Flagellospora curvula n.gen., n.sp.Of the sixteen alder-leaf Hyphomycetes, all except three (Tetracladium setigerum, Heliscus longibrachiatus and Flagellospora curvula) have been grown in pure culture on malt agar and oatmeal agar.In some genera (Clavariopsis, Tetracladium, Articulospora, Tetrachaetum, Tricladium, Lunulospora and Anguillospora) the spore form on which the genus is based is an aleuriospore, while in others (Lemonniera, Margaritispora, Heliscus, Alatospora and Flagellospora) it is a phialospore. In Varicosporium the spore is probably best regarded as a radulaspore.The possible biological value of the branched spore and of the long, curved spore is discussed, and it is suggested that this value may lie in the ease with which these spores become entangled in the decaying leaves of the stream-bed.It is suggested that in fitting these fungi into the recent scheme of classification of Hyphomycetes proposed by Wakefield and Bisby (1941), the best plan is to place them in the Gloiosporae, and to extend the definition of that group to include not only genera based on śslime spores’ but also genera founded on ‘aquatic spores’ produced, liberated and normally dispersed below water.
Article
The periodicity of 30 species of water mould, belonging to the orders Blastocladiales, Saprolegniales, Lagenidiales, and Peronosporales, inhabiting six alkaline ponds near Lucknow, India, was found to be governed significantly by factors such as water temperature, dissolved oxygen and calcium.
