Notes — Penicillium vanoranjei is c

Notes — Penicillium vanoranjei is characterised by colonies
dominated by bright orange sclerotia. Orange sclerotia also
occur in P. sclerotiorum and P. johnkrugii in the P. sclerotiorum
species-complex (clade 1), as recently revised by Rivera &
Seifert (2011). Penicillium sclerotiorum was distinguished from
P. johnkrugii based on more abundant conidiogenesis on CYA,
orange sclerotia on most media and subspheroidal to ellipsoidal
conidia in the former species, in contrast to orange sclerotia
produced only on MEA and spheroidal to subspheroidal conidia
in the latter. The new species is easily distinguished from
P. sclerotiorum by the absence of conidiogenesis on CYA and
spheroidal to subspheroidal conidia. The orange sclerotia of
P. vanoranjei, produced on most media, distinguish it from
P. johnkrugii. Also, the new species has more restricted growth
on CYA. It must be noted that roughness on conidia of P. vanoranjei,
although easily visible on SEM, was inconspicuous
with light microscopy.
