“…Petch (1907) transferred this species to Psalliota on the basis of some greenish tints in the early stage of basidioma development and the presence of free lamellae rather than adnexed. Heinemann and Little Flower (1984) This species was originally described from Taiwan and was placed in Hymenagaricus subgen. Xanthagaricus on account of pseudoparenchymatous pileus squamules and brownish-yellow basidiospores.…”

“…Xanthagaricus epipastus and X. taiwanensis are most closely related to X. pakistanicus among the species sampled for our phylogenetic analyses. X. epipastus and X. taiwanensis were originally described from Sri Lanka and Taiwan, respectively (Heinemann and Little Flower, 1984;Ge et al, 2008). The new species X. pakistanicus with globose to subglobose basidiospores can be differentiated from both X. epipastus and X. taiwanensis, which have ellipsoid spores.…”

“…species, the pileus disc is often covered with a single large squame, made up of hymeniform hyphae, and the basidiospores are brownish. While in Xanthagaricus, the squamules on the pileus are disrupted as the basidioma matures and the pileus disc is usually covered with more than one large squamule, consisting of hymeniform or pseudoparanchymatous cells, and the basidiospores are yellowish (Heinemann and Little Flower, 1984;Little Flower et al, 1997). These characters have led to the inclusion of 12 species in the genus Xanthagaricus (Little Flower et al, 1997;Reid and Eicker, 1998), mostly distributed in equatorial paleotropics (Ge et al, 2008).…”

Xanthagaricus pakistanicus is described as a new species from lowland northern Pakistan, based on morphological and molecular data. It is characterized by a yellowish pileus, covered with dark brown squamules, a stipe with yellowish fibrils, globose basidiospores, and pileal squamules made up of pseudoparenchymatous epithelium with encrusted walls. Molecular phylogenetic trees were inferred based on nucleotide sequences of the internal transcribed spacer (ITS1-5.8S-ITS2) region and 28S nuclear ribosomal DNA. In phylogenetic analyses the genus Hymenagaricus sensu lato (s. l.) was inferred as a nonmonophyletic group and recovered in two monophyletic clades, consisting of species of the genera Xanthagaricus and Hymenagaricus sensu stricto (s. str.). On account of the pileal squamule structure (pseudoparenchymatous epithelium) and yellowish basidiospores, and the phylogenetic position in the Xanthagaricus clade the new species X. pakistanicus belongs to the genus Xanthagaricus. Morphoanatomical comparison with the known species of Xanthagaricus is provided. We also made six new combinations in Xanthagaricus: X. calicutensis, X. epipastus, X. ochraceoluteus, X. rufomarginatus, X. subaeruginosus, and X. taiwanensis. With this study the number of known species in the genus Xanthagaricus increases to 19.

Two important volumes facilitating the identification of plant-parasitic fungi are welcomed: BRANDENBURGER (1985) compiled a vast amount of literature data on parasitic fungi (excluding macromycetes) that attack vascular plants in Europe;ELLIS and ELLIS (1985) present very useful observations and some keys as well as original illustrations on a more critically selected range of fungi growing on land plants, mainly British, also arranged according to host substrates. A volume on fungus-insect relationships (WHEELER and BLACKWELL 1984) contains chapters on the evolution of symbiotic associations.In a review of protein and nucleic acid sequences and ultrastructure data as a basis for the reconstruction of eukaryote phylogeny, McQUADE (1983) concludes that great uncertainty on the origin of the eumycetes persists, but the models available so far are consistent with the hypothesis that the chytrids represent ancestors to the eumycetes. PRILLINGER (1984) continued his previously reported studies on the nuclear conditions in chitinous fungi . Yeasts or yeast-like growth are considered a primitive type of morphological organization. The previously postulated evolution from mitotic to meiotic propagation is supported by further data. The capacity to form vegetative anastomoses is interpreted as an advanced character. a) Development of Fruit-bodiesIn his last paper, CHADEFAUD (1984) summarized his controversial views on the development of the "gametophytic gyno-carpophore" in the asco-and basidiomycetes. (More under Sect. 8.c . , Basidiomycota). b) ChemotaxonomyThe distribution of ubiquinones in 218 species of the major families of higher fungi shows a remarkable uniformity, with the Q-I0(H ) system predominating in the Pyrenomycetes and Dothideales and the Q-9 system in the Homobasidiomycetes; Heterobasidiomycetes have either Q-9 or Q-10. Greater diversity is found among the Plectomycetes and i~~-~~-our previous contributions . the second author deals with the taxonomy of basidiomycetes and the senior author with remaining groups.

A monograph of Micropsalliota in Northern Thailand based on morphological and molecular data

View full text Add to dashboard Cite

Using a combination of morphological and molecular data, the genus Micropsalliota is shown to represent a monophyletic lineage in the Agaricaceae sister to Hymenagaricus. Features that distinguish the genus from Agaricus and allied genera include usually small, gracile basidiomes with a membranous partial veil, dextrinoid basidiospores with an apically thickened endosporium and lack of a germ pore, capitate or subcapitate, conspicuous cheilocystidia, and incrusted pileipellis hyphae that turn green in ammonia solution. We provide a monographic treatment of 23 taxa of Micropsalliota from Northern Thailand, of which 13 taxa represent new distribution reports for Thailand and 10 represent new taxa, including M. allantoidea, M. bifida, M. furfuracea, M. lateritia var. vinaceipes, M. megarubescens, M. megaspora, M. pusillissima, M. rubrobrunnescens var. rubrobrunnescens, M. rubrobrunnescens var. tibiicystis, and M. suthepensis. Included in this monograph are comprehensive descriptions, illustrations of micromorphological features, photographs of basidiomes, comparisons with allied species, phylogenetic trees inferring relationships amongst Thai species based on nrITS and nrLSU sequence datasets, and a key to aid in diagnosis.
