MATOUŠ J., HOLEC J., KOUKOL O. (2017): Ramariopsis robusta (Basidiomycota, Clavariaceae), a new European species similar to R. kunzei. [ramarioid fungi, clavarioid fungi, taxonomy, phylogeny, 28S rDNA, Central Europe] Czech Mycology 69(1): 51-64 (published: 12th May, 2017)
abstract
The new species Ramariopsis robusta Matouš & Holec is described based on collections from the Czech Republic and Slovakia. The species is highly supported in a phylogenetic tree based on the 28S rDNA gene. Morphologically, it is distinguished by its robust and densely branched white to cream basidiomata often growing in fascicles, with wide, often flattened branches, and distinctly ornamented spores with up to 1.5 μm high spines. The most similar species R. kunzei differs by subtler, more sparsely branched basidiomata, lower spore ornamentation, smaller Q value and shorter basidia. The species is described in detail and figures showing its macro- and microcharacters are provided including SEM photographs of spores. Differences with the similar taxa R. kunzei (including its varieties), R. atlantica, R. bispora, R. tenuiramosa, R. biformis, R. rufipes and Clavaria lentofragilis are outlined. Ramariopsis atlantica is newly documented from Panama.

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 Published and unpublished records of 117 species are listed, including those of some terrestrial hyphomycetes found in stream foam.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).
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.
