Morphological Differences

Grammothele and Theleporus have a shallow pore surface, which makes them morphologically close to corticioid fungi. However, from a phylogenetic perspective, they are polyphyletic genera within the core polyporoid clade of the Polyporales. Eight specimens with a shallow pore surface from Hainan, southern China, were morphologically and phylogenetically studied. Among them, one was determined as Grammothele denticulata, four were identified as Theleporus membranaceus, and three are described as Grammothele hainanensis. G. hainanensis is characterized by the annual and resupinate basidiocarps with poroid to irpicoid hymenophore, a dimitic hyphal system with clamped generative hyphae and weakly dextrinoid skeletal hyphae, the presence of cystidioles, hyphal pegs and dendrohyphidia, and cylindrical, hyaline and thin-walled basidiospores. It is closely related to G. quercina in phylogeny. Morphologically, G. quercina differs in producing perennial basidiocarps with cream to pale greyish and larger pores. The morphological differences among the new species and other species were analyzed.

Phylogenies of Ceriporiopsis and related genera were studied using DNA sequences from the ITS+28S nuclear ribosomal RNA gene regions. Two species, Ceriporiopsis alboaurantia and C. semisupina, are described as new to science. Ceriporiopsis alboaurantia is characterized by annual growth habit, resupinate basidiocarps with white pore surface when fresh, turning to apricot-orange to dark orange upon drying, monomitic hyphal system with clamped generative hyphae encrusted with pale yellow crystals, ellipsoid and thin-walled basidiospores (4–5 ´ 3–3.3 µm), and plenty of pale-yellow to pale-orange oily substances in subiculum and trama. Ceriporiopsis semisupina is distinguished by annual, effused-reflexed basidiocarps with greyish brown to reddish brown pore surface, monomitic hyphal system with clamped generative hyphae bearing crystalline incrustation, long-clavate basidia, ellipsoid and thin-walled basidiospores (4–4.5 ´ 3–3.3 µm). Like previous study, the phylogenetic analysis presented here also showed that Ceriporiopsis is not monophyletic and the sampled species were grouped in four clades, including phlebia clade, residual polyporoid clade, tyromyces clade and gelatoporia clade.

Fuscoporia (Hymenochaetaceae) is characterized by annual to perennial, resupinate to pileate basidiocarps, a dimitic hyphal system, presence of hymenial setae, and hyaline, thin-walled, smooth basidiospores. Phylogenetic analyses based on the nLSU and a combined ITS, nLSU and RPB2 datasets of 18 species of Fuscoporia revealed two new lineages that are equated to two new species; Fuscoporia ramulicolasp. nov. grouped together with F. ferrea, F. punctatiformis, F. subferrea and F. yunnanensis with a strong support; Fuscoporia acutimarginatasp. nov. formed a strongly supported lineage distinct from other species. The individual morphological characters of the new species and their related species are discussed. A key to Chinese species of Fuscoporia is provided.

Two new wood-decaying polypores from southern China, Grammothele separabillima and Theleporus rimosus, are described and illustrated using morphological characteristics and rDNA ITS sequences. Grammothele separabillima is characterized by its easily separable basidiocarps, poroid hymenophore with hymenium restricted to the base of the tubes, a dimitic hyphal system, pale brown skeletal hyphae with dextrinoid reaction, presence of dendrohyphidia, and oblong ellipsoid basidiospores. Theleporus rimosus is characterized by its resupinate, cracked basidiocarps, shallow poroid hymenophore with hymenium restricted to the base of the tubes, a di-trimitic hyphal system with dendroid and non-dextrinoid skeletal hyphae, presence of dendrohyphidia and ellipsoid to fusiform basidiospores. The discriminating characters of these two new species and the closely related species are discussed.

Recent Evaluation

The cycad genus Dioon comprises 17 species from Mexico and Honduras, all of them delimited based on their morphological variation and geographic distribution. A recent evaluation of the biological variation among Dioon populations from Oaxaca and Chiapas, Mexico, demonstrated that the concept of the species Dioon merolae actually consists of three lineages that should be recognized as different taxa. One lineage was already described as Dioon oaxacensis, leaving the concept of Dioon merolae comprising two lineages distributed on both sides of the Isthmus of Tehuantepec. However, there are conspicuous morphological differences between these two lineages. Here, we tested whether such a differentiation within the concept of Dioon merolae merits the differentiation of two different taxa. We evaluated the qualitative and morphometric variation among populations belonging to the Dioon merolae lineages, and compared it with the closely related species Dioon oaxacensis. Morphological observations and statistical tests demonstrated that the populations of southeastern Oaxaca, traditionally considered as part of Dioon merolae, represent a distinct species that we described as Dioon salas-moralesae. Identifying the diagnostic characters of this new species helps enable an understanding of the criteria that should be considered to delineate the boundaries between other cycad species.

Inference Methods

Two new species, Xylodon bambusinus and X. xinpingensis, are proposed based on morphological and molecular evidences. Both species share the annual growth habit, resupinate basidiomata and monomitic hyphal system with clamped, colorless generative hyphae, smooth, thin-walled basidiospores, but X. bambusinus is characterized by the smooth to tuberculate hymenial surface, presence of capitate and fusiform cystidia, broad ellipsoid basidiospores, while X. xinpingensis by the reticulate hymenophore with cream hymenial surface, and subglobose basidiospores (4.5–6 × 3.5–5 µm). Sequences of ITS and LSU nrRNA gene regions of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony and Bayesian inference methods. The phylogenetic analyses based on molecular data of ITS and ITS+nLSU sequences showed that X. bambusinus was sister to X. subclavatus, while X. xinpingensis grouped with X. astrocystidiatus and X. paradoxus. The nLSU dataset revealed that X. bambusinus grouped with X. asperus and X. brevisetus with lower supports, and that X. xinpingensis grouped with X. astrocystidiatus and X. paradoxus and then with X. rimosissimus without supports. Both morphological and molecular evidences confirmed the placement of two new species in Xylodon. Description and figures from the new species and a key to the known species of Xylodon from China are presented.

Six new species of the spider genus Tonsilla Wang & Yin, 1992 are described from southern China: T. jinyunensis sp. nov. (♂♀) from Chongqing, T. jiugongensis sp. nov. (♂♀) from Hubei, T. subtruculenta sp. nov. (♂♀), T. rutunda sp. nov. (♂♀) and T. yueliangensis sp. nov. (♂) from Guizhou and T. subrostrum sp. nov. (♂♀) from Hunan. In addition, T. yanlingensis (Zhang, Yin & Kim, 2000) is redescribed and its male is described here for the first time. Tonsilla subyanlingensis Liu & Xu, 2020 is transferred to Draconarius Ovtchinnikov, 1999, hence the new combination Draconarius subyanlingensis (Liu & Xu, 2020) comb. nov. is established. The female of T. subyanlingensis Liu & Xu, 2020 should be treated as T. yanlingensis (Zhang, Yin & Kim, 2000). Detailed descriptions, photographs of copulatory organs and somatic features, a distribution map and comparisons with closely related species are presented.

A new species of Fistulina, F. tasmanica sp. nov., is described and illustrated from Tasmania in Australia. Fistulina tasmanica is distinguished by its pileate and fleshy basidiomata with rose pore surface, fibrous context, separated tubes with small pores (6–7 per mm), a monomitic hyphal system with only clamped generative hyphae, subellipsoid to ellipsoid basidiospores (5.4–6 × 3.4–4 μm) which are negative in Melzer’s reagent and cotton blue. Phylogenetic analyses inferred from the internal transcribed spacer regions (ITS) and the large subunit of nuclear ribosomal RNA gene (nLSU) sequences also confirmed that F. tasmanica is a new member within Fistulina.

A New Species

A re-examination of the herbarium material has allowed to describe a new species, Corbichonia exellii, occurring in Southern Africa (Angola, Namibia and South Africa). C. exellii represents the third species in the genus. Morphological differences between all three Corbichonia species (C. decumbens, C. rubriviolacea, and C. exellii) are provided. The description of the genus is defined using the newly discovered characters (reproductive features). The taxonomy of all Corbichonia species (synonyms included) is provided, as well as maps for all species. The lectotypes of Orygia decumbens (basionym of Corbichonia decumbens) and O. mucronata (synonym of C. decumbens) are designated on specimens preserved, respectively, at BM and K. The genus Corbichonia, recently placed in Lophiocarpaceae, is markedly different from the core genus Lophiocarpus on the basis of embryological, morphological and carpological characters, and deserves further investigation concerning its taxonomic status.

Myrcia adulterina, a new species from the Brazilian Atlantic Forest, is here described, illustrated and compared with morphologically related species. Additionally, its distribution map and a preliminary conservation status are presented. The new species is here inferred as belonging to Myrcia sect. Reticulosae due its leaves with raised venation, staminal ring densely pilose, hypanthium prolonged in a tube with glabrous inner walls and 3-locular ovaries. Within this section, the species is morphologically related to Myrcia pubipetala, from which it can be distinguished through the laxly reticulate leaf venation and thyrsoid inflorescences with all axes strongly flattened and striated when dry. Myrcia adulterina was misidentified during at least 15 years in herbaria under the name Marlierea tomentosa (currently synonym of Myrcia strigipes, a species belonging to Myrcia sect. Aulomyrcia), which is also morphologically similar. A brief discussion clarifying the morphological differences between these species is also presented.
