A new species of Ceratocystis with a Chalara anamorph was observed to cause black stains on the cut surfaces of recently felled Eucalyptus obliqua logs in south-western Tasmania, Australia. It is described as C. moniliformopsis because of its similarity to C. moniliformis in morphology of ascospores and perithecia. This is a homothallic species and is characterised by a thick perithecial peridium, ovoid perithecia and disciform-based perithecial necks with convergent ostiolar hyphae. The perithecia are covered with the following two types of ornamenting hyphae: hyaline, thin-walled, aseptate, tubular hairs and dark brown, thick-walled, ampliform to conical setae. Its Chalara anamorph has the following two types of conidiogenous cells: hyaline, cylindrical tapering phialides and pigmented, cupulate or divergent phialides with percurrent proliferation. The latter is a unique type of conidiogenous cell that has not been observed in this genus before the present study.

Two new genera with phylogenetic affinities to Phanerochaete s.l. are presented, namely Hydnophanerochaete and Odontoefibula. The generic type of Hydnophanerochaete is Phanerochaeteodontoidea. Odontoefibula is established based on a new species: O.orientalis (generic type). Both genera have effused basidiocarps with odontioid hymenial surface, simple-septate generative hyphae, cystidia lacking, clavate basidia and ellipsoid basidiospores that are smooth, thin-walled, inamyloid, non-dextrinoid and acyanophilous. Hydnophanerochaete is additionally characterised by a compact texture in the subiculum with thick-walled generative hyphae and quasi-binding hyphae. Odontoefibula has a dense texture of subiculum with thin- to slightly thick-walled hyphae and further a dark reddish reaction of basidiocarps when treated with KOH. Multi-marker phylogenetic analyses based on sequences, inferred from the ITS+nuc 28S+rpb1+rpb2+tef1 dataset, indicate that Hydnophanerochaete and Odontoefibula are placed in the Meruliaceae and Donkia clades of Phanerochaetaceae, respectively. Phanerochaetesubodontoidea is a synonym of P.odontoidea, according to morphological and molecular evidence.

Kiliophora is a hyphomycete genus whose species are involved in leaf litter decomposition. It was originally described with polytretic conidiogenesis. Based on observation of fresh specimens collected in Brazil and bibliographic revision, an emended description is proposed in order to rectify the mode of conidial production. The presence of minute polar extensions at both ends of conidia is stated as a diagnostic generic character. A new species, Kiliophora clavatophora, and a new combination, Kiliophora aseptata, are proposed. The new species is characterized by its conidiophores with clavate apical cell, its ellipsoidal conidiogenous cell and fusiform conidia. A table for comparison of all accepted species is also included.

Efibula yunnanensis is proposed as a distinct new species based on morphological and molecular phylogenetic data. The species is characterized by an annual growth habit, resupinate basidiomata with smooth, cream to pale brown hymenial surface, a monomitic hyphal system with thin-walled, simple septate generative hyphae and ellipsoid, hyaline, thin-walled, smooth, IKI-, CB-basidiospores. The phylogenetic analyses based on ITS sequence data analyses revealed that E. yunnanensis was sister to a clade comprised E. clarkii and E. gracilis, and then grouped with E. americana and E. tuberculata.

Humicola dimorpliospora is described as a new species. It is pleomorphic, producing dark, thick-walled, holoblastic conidia from portions of the vegetative hyphae as the principal spore type and hyaline, thin-walled, holoblastic conidia from sympodially proliferating conidiogenous cells as the secondary. The secondary spore type is characteristic of the genus Sporothrix. The type culture, ATCC 22422, was isolated from Saskatchewan soil, Canada, and is being preserved by freeze-drying and by storage in liquid nitrogen at – 196C. The range of temperature for growth of the fungus is 10 to 30C.

Obba thailandica sp. nov. is described and illustrated from northern Thailand based on evidence from morphological characteristics and molecular data. The species produces annual, resupinate, white and waxy fresh basidiocarps, which become bone hard when dry, and has a very thin subiculum (< 0.1 mm), tomentose tube openings, weakly dextrinoid hyphae, variably shaped cystidioles, thin-walled and subglobose to globose basidiospores (4.8–5.8 × 4–4.9 μm) mostly with a large guttule and grows on charred pine wood. The new taxon is rather similar to O. rivulosa in both morphology and ecology, but O. rivulosa has fragile tubes when dry, a thick subiculum (up to 1 mm wide), smooth tube openings, indextrinoid hyphae, rhomboidal to irregular rosettes crystals on the tramal hyphae and long basidia (16–27 × 6–9.5 µm). In the phylogeny inferred from an ITS dataset, the new species forms a distinct lineage in the Obba clade and is closely related to O. rivulosa.

Basidiocarps of an undescribed dacrymycetous species were collected from Pinus densiflora forests in Japan and described as a new species, Femsjonia uniseptata, based on both morphological characteristics and phylogenetic analysis. This new species is characterized by having discoid to applanate basidiocarps with white hairs at the margins; thin-walled internal and marginal hyphae with clamp connections; and 0–1-septate basidiospores. A detailed description, line drawings, phylogenetic tree to show the placement of F. uniseptata and comparison of the new species with allied taxa are provided.

A new species, Roseodiscus sinicus is described and illustrated. The fungus, collected on stems of an unknown monocotyledon, is characterized by dirty white apothecia, large and thin-walled ectal excipulum cells, Calycina-type ascus apical ring, and ellipsoid, multiguttulate ascospores. The placement of the new species in Roseodiscus was also supported by ITS rDNA sequence analysis. The distinctions between the new species and related taxa are discussed.

Background and Aims: Hymenochaete is the genus with the highest number of species of the family Hymenochaetaceae in Mexico; 25 species have been described. It is characterized by its mainly resupinate basidiome, although it may be pileate and stipitate, of brown colors, with presence of setae and xanthocroid reaction. The objective of this study is to describe a new species of Hymenochaete.Methods: The fresh material was studied and described macro and micromorphologically, using a stereoscopic and optical microscope, taking photos in situ. Vouchers of the herbaria ENCB y FCME were studied, and specialized literature was reviewed for its description.Key results: Hymenochaete liliae sp. nov. is characterized by a resupinate, adnate, fleshy basidiome, smooth hymenophore, with numerous setae, determinate margin, abrupt, with monomitic hyphal system, simple septae; abundant subfusiform setae in the hymenium, 69-80 × 6-8 µm, acute, with crystals; and ellipsoid basidiospores, thin-walled, 5-8 × 2-3 µm. Although it resembles H. rhabarbarina, it can be differentiated by setae covered with crystals and spores of 4.8-6 × 2.3-3.3 µm. It could also be confused with H. minuscula due to its basidiome color; however, the setae are smaller (40-60 µm), as well as the basidia (15-20 µm). It can be separated from H. cinnamomea because it does not present a stratose basidiome; setae with crystals, 69-80 × 6-8 µm; basidiospores 5-8 × 2-3 µm, ellipsoidal.Conclusions: Hymenochaete liliae is proposed as a new species, which is distributed in the tropical dry forest of the state of Oaxaca, and until now only reported from the type locality.

A new species is described from tropical China as Porpomyces submucidus on the basis of both morphological characters and molecular evidence. Phylogenetic analyse based on the ITS sequence, LSU sequence and the ITS+LSU sequence show that the new species belongs to Porpomyces and forms a distict clade as a sister group of Porpomyces mucidus. The fungus is characterized by thin, white to cream, resupinate basidiome with cottony to rhizomorphic margin, small pores (7–9 per mm), a monomitic hyphal structure with clamped generative hyphae, usually ampullated at most septa, and small, hyaline, thin-walled, ellipsoid basidiospores measuring 2.2–2.8 × 1.2–1.8 μm. It is closely related to Porpomyces mucidus, but the latter has larger pores (4–5 per mm) and larger basidiospores (2.8–3.9 × 2–2.8 μm).
