Penicillium species were commonly isolated during a fungal survey of bat hibernacula in New Brunswick and Quebec, Canada. Strains were isolated from arthropods, bats, rodents (i.e. the deer mouse Peromyscus maniculatus), their dung, and cave walls. Hundreds of fungal strains were recovered, of which Penicillium represented a major component of the community. Penicillium strains were grouped by colony characters on Blakeslee's malt extract agar. DNA sequencing of the secondary identification marker, beta-tubulin, was done for representative strains from each group. In some cases, ITS and calmodulin were sequenced to confirm identifications. In total, 13 species were identified, while eight strains consistently resolved into a unique clade with P. discolor, P. echinulatum and P. solitum as its closest relatives. Penicillium speluncae is described using macroand micromorphological characters, multigene phylogenies (including ITS, beta-tubulin, calmodulin and RNA polymerase II second largest subunit) and extrolite profiles. Major extrolites produced by the new species include cyclopenins, viridicatins, chaetoglobosins, and a microheterogenous series of cyclic and linear tetrapeptides.

Scrophularia dianatnejadii Ranjbar & Rahchamani, a new species from Tehran Province in northern Iran, is described and illustrated. It is closely related to S. amplexicaulis Benth. and shares with it some diagnostic morphological characters such as habit, plant indument, phyllotaxy, and corolla shape and color. Both species are placed in Scrophularia L. sect. Mimulopsis Boiss. Macro- and micromorphological characters of the two are examined and compared. Pollen morphology of these species is investigated using SEM. Detailed descriptions, illustrations, distribution maps, and conservation status of both species are provided.

Two species of Xanthagaricus discovered in Hubei Province of China are described based on the macro- and micromorphological features. Their identity is further supported by molecular analysis of the internal transcribed spacer (ITS) of the ribosomal RNA gene. The phylogeny obtained here showed that one of the Chinese species is nested in an exclusive clade which in combination with its striking morphological features, infers that it represents a new species, named X. ianthinus, while the other species is placed as a member in the X. epipastus clade. Descriptions are accompanied with illustrations of macro- and micromorphological characters and a discussion of related taxa is presented.

Sinosenecio ovatifolius (Asteraceae, Senecioneae), a new species occurring in northeastern Guangxi, China, is illustrated and de-scribed with report on its floral micromorphological characters, achene surface feature and chromosome number. The new spe-cies is phylogenetically close to S. guangxiensis, S. jiangxiensis, S. jiuhuashanicus, S. latouchei, S. peltatus, S. saxatilis, and S. wuyiensis. Morphology and sequence divergence of the nrITS region indicate that S. ovatifolius is well differentiated from its close relatives. It most closely resembles S. guangxiensis and S. latouchei in the scapigerous habit, leaf texture and indumentum, but differs markedly in the ovate lamina, inconspicuously undulate-dentate margin and glabrous and smooth achene surface.

A new tardigrade species, Diphascon (Diphascon)burti, is described from lichens and mosses in New Brunswick, Canada. It differs from other species of the genus Diphascon by the presence of two macroplacoids, a large flared septulum, and a transverse pseudoseptulum. A pseudoseptulum has been reported previously in only one species from Antarctica. The description of D. burti increases the number of Diphascon species recorded from Canada to 15.

Sixteen sponge species were recorded from Little Letite Passage, an area of highvelocity tidal currents located in the Bay of Fundy near Deer Island, New Brunswick, Canada. Of these 16 species, four species (Myxilla fimbriata, Hymeniacidon heliophila, Hemigellius sp. aff. flagellifer, and Crella rosea) have not previously been recorded from the Bay of Fundy. One new species, Hymedesmia canadensis, is described, based on the presence of a second peculiar chelate microsclere added to the spicule armament.

Inocybe griseorubida sp. nov. is described from Kerala State, India. A comprehensive description, photographs, and comparisons with phenetically similar species are provided. The nuclear ribosomal internal transcribed spacer region (ITS), a portion of the nuclear ribosomal large subunit (nLSU) and a portion of the nuclear second-largest subunit of RNA polymerase II (rpb2) gene of this species were sequenced and analyzed. Phylogenetic analysis of rpb2 sequences confirmed both the novelty of the species and its placement within the Pseudosperma clade.

A fungal survey of the Gcwihaba Cave from Botswana found Aspergillus to be one of the more common fungal genera isolated. The 81 Aspergillus strains were identified using CaM sequences and comparing these to a curated reference dataset. Nineteen species were identified representing eight sections (sections Candidi, Circumdati, Flavi, Flavipedes, Nidulantes, Nigri, Terrei and Usti). One strain could not be identified. Morphological characterisation and multigene phylogenetic analyses confirmed it as a new species in section Flavipedes and we introduce it below as A. okavangoensis. The new species is most similar to A. iizukae, both producing conidiophores with vesicles typically wider than 20 µm. The new species, however, does not produce Hülle cells and its colonies grow slower than those of A. iizukae on CYA at 37 °C (14–15 vs 18–21 mm) and CREA (15–16 vs 23–41mm).

A survey of Penicillium in the fynbos biome from South Africa resulted in the isolation of 61 species of which 29 were found to be new. In this study we focus on Penicillium section Canescentia, providing a phylogenetic re-evaluation based on the analysis of partial beta-tubulin (BenA), calmodulin (CaM) and RNA polymerase II second largest subunit (RPB2) sequence data. Based on phylogenies we show that five fynbos species are new and several previously assigned synonyms of P. canescens and P. janczewskii should be considered as distinct species. As such, we provide descriptions for the five new species and introduce the new name P. elizabethiae for the illegitimate P. echinatum. We also update the accepted species list and synonymies of section Canescentia species and provide a review of extrolites produced by these species.

A new, narrowly endemic species from the Andean western slopes of central Peru, Chusquea limensis (Poaceae, Bambusoideae, Bambuseae), is described and illustrated. Identification keys and a comparative table based on vegetative and reproductive characters, including morphologically similar species such as C. huantensis, C. inamoena, C. scandens and C. tarmensis, as well as habitat and geographical distribution notes, are included. Additionally, anatomical and micromorphological characters of the culm and foliage leaf blades of the new species are presented, as a valuable tool for the identification of sterile specimens.
