Abstract
In this article we report on a hexactinellid sponge new to science, Tretopleura weijicus sp. nov., which was collected from the Weijia Seamount in the northwestern Pacific Ocean at a depth of 1995 m. Its blade-like and branching body form, the primary choanosomal framework consisting of multiaxial longitudinal strands without synapticula, and the presence of sceptrules suggest placement within the family Uncinateridae Reiswig, 2002, which is also supported by molecular phylogenetic evidence from COI and 16S sequences. The absence of swollen dermal spurs or regular pentactins and the presence of two types of discohexasters characterize it as a new species. More specimens should be collected to revise the generic characters.

Abstract
Two new anamorphic fungi, Blodgettia chinensis sp. nov. and Nigrolentilocus saprophyticus sp. nov., are described and illustrated from specimens collected on dead branches of unidentified plants in southern China. Blodgettia chinensis is characterized by monoblastic, integrated, terminal conidiogenous cells that produce broadly ellipsoidal, 5-euseptate, smooth conidia with darkened and thickened bands at the septa. Nigrolentilocus saprophyticus is distinguished by its polyblastic, sympodially extending, terminal and intercalary, integrated conidiogenous cells with conspicuous, lenticular conidiogenous loci and ellipsoidal to fusiform, 3-euseptate, versicolored conidia. A key to Nigrolentilocus species is provided. Anapleurothecium botulisporum is recorded for the first time from China.
