Molecular taxonomy of bambusicolous fungi: Tetraplosphaeriaceae, a new pleosporalean family with Tetraploa-like anamorphs
A new pleosporalean family Tetraplosphaeriaceae is established to
accommodate five new genera; 1) Tetraplosphaeria with small ascomata
and anamorphs belonging to Tetraploa s. str., 2)
Triplosphaeria characterised by hemispherical ascomata with rim-like
side walls and anamorphs similar to Tetraploa but with three conidial
setose appendages, 3) Polyplosphaeria with large ascomata surrounded
by brown hyphae and anamorphs producing globose conidia with several setose
appendages, 4) Pseudotetraploa, an anamorphic genus, having
obpyriform conidia with pseudosepta and four to eight setose appendages, and
5) Quadricrura, an anamorphic genus, having globose conidia with one
or two long setose appendages at the apex and four to five short setose
appendages at the base. Fifteen new taxa in these genera mostly collected from
bamboo are described and illustrated. They are linked by their Tetraploa
s. l. anamorphs. To infer phylogenetic placement in the
Pleosporales, analyses based on a combined dataset of small- and
large-subunit nuclear ribosomal DNA (SSU+LSU nrDNA) was carried out.
Tetraplosphaeriaceae, however, is basal to the main pleosporalean
clade and therefore its relationship with other existing families was not
completely resolved. To evaluate the validity of each taxon and to clarify the
phylogenetic relationships within this family, further analyses using
sequences from ITS-5.8S nrDNA (ITS), transcription elongation factor 1-α
(TEF), and β-tubulin (BT), were also conducted. Monophyly of the family
and that of each genus were strongly supported by analyses based on a combined
dataset of the three regions (ITS+TEF+BT). Our results also suggest that
Tetraplosphaeria (anamorph: Tetraploa s. str.) is an
ancestral lineage within this family. Taxonomic placement of the bambusicolous
fungi in Astrosphaeriella, Kalmusia, Katumotoa, Massarina,
Ophiosphaerella, Phaeosphaeria, Roussoella, Roussoellopsis, and
Versicolorisporium, are also discussed based on the SSU+LSU
phylogeny
