MARVANOVÁ L., MARVAN P. (1969): Aquatic Hyphomycetes in Cuba. Česká Mykologie 23(2): 135-140 (published: 1969)
abstract
The present paper gives some information on the occurrence of aquatic Hyphomycetes in Cuba. The list of the species found indicates a close floristic relationship with those of the neighbouring island of Jamaica. Among some rarely observed representatives of aquatic Hyphomycetes, the occurrence of the species Pyramidospora casuarinae must be pointed out, because up till now, it has been known with certainty only from its original locality.
GHATE S.D., SRIDHAR K.R. (2016): Aquatic hyphomycetes associated with leaves, leaf detritus and crown humus in palm canopies. [Caryota urens, Cocos nucifera, hyphomycetes diversity, abiotic factors, dry and wet season, India] Czech Mycology 68(2): 111-126 (published: 8th July, 2016)
abstract
Aquatic hyphomycetes associated with attached dead leaves (autochthonous), accumulated leaf litter (allochthonous) and crown humus in canopies of wild palm (Caryota urens) and cultivated palm (Cocos nucifera) were assessed during wet and dry seasons by means of bubble chamber incubation.The canopy of C. urens trapped allochthonous leaf litter of seven tree species (Alstonia scholaris, Artocarpus hirsutus, Ficus benghalensis, F. religiosa, Garcinia indica, Holigarna arnottiana and Mangifera indica), while in the canopies of C. nucifera leaf litter of four tree species was found (Acacia mangium, Delonix regia, Eucalyptus tereticornis and Polyalthia longifolia). Although the total number of species of aquatic hyphomycetes was almost identical during the dry season (17-18 spp.), in the wet season it was higher in Caryota urens than in Cocos nucifera (31 vs. 23 spp.). Based on conidium production, Anguillospora crassa, Flagellospora curvula and Lunulospora curvula were among the top five species during the wet and dry seasons in both palms.Shannon diversity was higher in the wet season than in the dry season in all samples of C. urens, while it was higher only in leaf samples of C. nucifera. Sřrensen’s similarity of aquatic hyphomycete communities between the samples was higher in C. urens than in C. nucifera. Three-way ANOVA revealed significant differences in species richness and conidium production between the seasons, palms and substrate assessed.
GHATE S.D., SRIDHAR K.R. (2015): Rain-borne fungi in stemflow and throughfall of six tropical palm species. [Canopy, hyphomycetes, conidia, species richness, diversity, abiotic factors] Czech Mycology 67(1): 45-58 (published: 29th May, 2015)
abstract
The present survey documents rain-borne hyphomycetes in stemflow and throughfall of six palm species on the west coast of India during the monsoon season. A total of 61 species were recovered.Irrespective of the palms, throughfall was represented by a higher number of species than stemflow.Pearson correlation was significant and positive between richness of species and conidia with air humidity, air temperature, water temperature and water conductivity. Except for Areca, Shannon diversity was higher in throughfall compared to stemflow. Jaccard’s percent similarity of species in stemflow was lowest between Cocos vs. Roystonea (16%) and highest between Borassus vs. Caryota (55.5%), while in throughfall it was lowest between Areca vs. Livistona (16.7%) and highest between Caryota vs. Cocos and Livistona vs. Cocos (50%).Two-way ANOVA revealed that the richness of species and that of conidia were significantly more dependent on palm species than stemflow or throughfall. The number of rain-borne fungi in palm species exceeded that in the nearby coastal stream with an overlap of about 40%.

abstract
The history of research on aquatic hyphomycetes from various aquatic and terrestrial habitats in Hungary since the early 1900s is presented. Published and unpublished records of 117 species are listed, including those of some terrestrial hyphomycetes found in stream foam.
BÄRLOCHER F., STEWART M., RYDER D. (2011): Analyzing aquatic fungal communities in Australia: impacts of sample incubation and geographic distance of streams. [aquatic hyphomycetes, zoosporic fungi, spore production, aeration vs. static incubation, temperature, geographic distance] Czech Mycology 63(2): 113-132 (published: 10th August, 2011)
abstract
Fungal colonization of Eucalyptus viminalis exposed in three streams (two sites each) near Armidale (NSW Tablelands, Australia) was characterized by measuring reproduction from recovered leaves in aerated and static water. Spore production for zoosporic and mitosporic fungi increased by up to 220 % and 310 %, respectively, in aerated water. Percentage similarities of aquatic hyphomycete communities between pairs of aerated and static samples from the same stream averaged 67.5 %; similarities among samples from different streams averaged 50.3 %. Canonical Analysis of Principal Coordinates (CAP) revealed no significant difference between fungal communities of aerated vs. static treatments summarized over all sites. The fungal communities of substrates from an additional nine streams, primarily from the coast, were characterized in September, 2010. They were compared to those on E. viminalis leaves incubated for four weeks at the original six sites. CAP revealed a significant difference between tableland and coastal fungal communities. Percentage similarities correlated significantly with geographic distance of the streams (R2 = 0.13), their temperature (R2 = 0.46) and their altitude (R2 = 0.65).
KARAMCHAND K.S., SRIDHAR K.R. (2008): Water-borne conidial fungi inhabiting tree holes of the west coast and Western Ghats of India. [tree holes, canopy, leaf litter, water-borne fungi, conidia, diversity] Czech Mycology 60(1): 63-74 (published: 4th July, 2008)
abstract
The present study focuses on water-borne conidial fungi associated with leaf litter in riparian tree holes of the west coast (Konaje) and Western Ghats (Sampaje) of India during dry (summer) and wet (monsoon) seasons. Out of a total of 34 fungal taxa recovered from leaf litter trapped in tree holes, 26 fully identified taxa constitute the first record for the tree hole habitat. Paired t-test revealed no significant difference in number of taxa (P = 0.1177) and conidial output (P = 0.1816) between Konaje and Sampaje tree holes, while they significantly differed between seasons of Konaje (P = 0.0258) and Sampaje (P = 0.0206). The Simpson and Shannon diversity of fungi were highest in Sampaje than Konaje tree holes. Tree-wise diversity of fungi revealed that banyan (Ficus benghalensis) tree holes are highly diverse during the summer and monsoon seasons in Konaje, but only during summer in Sampaje. In spite of a low conidial output, tree hole leaf litter of Konaje yielded 18 taxa against 20 taxa in the Konaje stream, wheras 29 taxa were recorded in Sampaje tree holes against 68 taxa in the Sampaje stream. The current study has been compared with earlier investigations on the occurrence of water-borne conidial fungi in tree canopies (e. g. intact leaves, leaf litter, tree holes, stemflow and throughfall).
GULIS V., SUBERKROPP K. (2003): The effect of excluding plant litter on the aquatic hyphomycete conidia in a headwater stream. [freshwater fungi, leaf litter, conidia concentration, community structure, seasonal patterns] Czech Mycology 54(3-4): 249-260 (published: 23rd May, 2003)
abstract
The concentrations and community structure of aquatic hyphomycete conidia in water were followed over a two-year period in two headwater streams at Coweeta Hydrologie Laboratory, NC, USA using the membrane filtration technique. Litter input into one stream was excluded for 6 years priorto and during the course of ourstudy whereas the reference stream received natural litter inputs during this time. This whole-stream substrate manipulation resulted in seasonal differences in maximum conidia concentrations in the two streams and shifts in dominant species or their rankings. However, total conidia concentrations were not significantly affected by the litter-exclusion treatment.
