This study introduces a new
Penicillium
species isolated from soil in Yavatmal, India.
Penicillium sanjayi sp. nov.
is classified in
Penicillium
section
Citrina
. The new species is delimited using ...phenotypic characters and sequences of the nuclear ribosomal internal transcribed spacer (ITS) rDNA regions, partial beta-tubulin (
BenA
), calmodulin (
CaM
), and RNA polymerase II second largest subunit (
RPB2
) region. Phylogenetic analyses consistently resolved the new species in a well-delineated clade with its close relative
P. vascosobrinhoanum
(originally published as
P. vascosobrinhous
), distinct from all other series of section
Citrina
. As a result, we introduce the series
Vascosobrinhoana
for this unique lineage. Key distinguishing characteristics such as greyish ruby to ruby centre of colonies (obverse) on malt extract agar (MEA), presence of cream colour sclerotia on oatmeal agar (OA), growth rates on standardised media, growth at 30 °C but lack of growth at 37 °C, additional microscopic characters such as solitary or rarely with a subterminal branch other than predominant monoverticillate penicilli, and conspicuously roughened to verruculose conidial ornamentation distinguish the new species
P. sanjayi
from other monoverticillate section Citrina species
.
This study resolves the phylogenetic position of an anamorphic synnematous genus, Gangliostilbe, (typified by G. indica) collected from the Northern Western Ghats of India. Gangliostilbe can be ...distinguished based on its erect synnemata, simple, dark-coloured, well-defined stalk, a subglobose to clavate head, and solitary, acrogenous, brown, phragmoconidia having three or more septa that secede through gangliar conidiogenesis. Phylogenetic analysis based on ITS and LSU sequence data supported the placement of Gangliostilbe in Xenospadicoidaceae (Xenospadicoidales). Gangliostilbe is the only genus in Xenospadicoidaceae having synnematous conidiomata and gangliar conidiogenesis.
