AbstractThree new species of Verrucaria are described from calcareous and calciferous rocks in Finland based on morphology and ITS sequences. The species are all members of the Endocarpon group in the Verrucariaceae. Verrucaria oulankaensis sp. nov. is related to V. cernaensis but differing in its usually pruinose, small areolate thallus. It occurs in NE Finland on calcareous and calciferous rocks on river shores. Verrucaria ahtii sp. nov. and V. vitikainenii sp. nov. form a sister group in the ITS phylogeny. Verrucaria vitikainenii differs from V. ahtii in the darker and thinner thallus, absence of a prothallus and in the perithecia, which lack thalline cover. Verrucaria ahtii morphologically resembles V. apomelaena but differs in having a thinner involucrellum and a fimbriate prothallus. It has a southern distribution in Finland and prefers sun-exposed sites, particularly pebbles in lime quarries. The species is also reported from Lithuania and Russia. Verrucaria vitikainenii has an eastern distribution in Finland. The species is a strict calcicole, preferring half-shady habitats. Verrucaria apomelaena is excluded from the Finnish lichen flora.

The Cryptini Eknomia Santos et Aguiar gen. nov. is proposed, described, and cladistically compared with representativespecies of 40 outgroup genera from twelve cryptine subtribes. A total of 98 morphological characters were evaluated. Allanalyses, conducted in TNT under implied and equal weighting, clearly suggest that Eknomia is a monophyletic groupand can be treated as a distinct genus. Its likely sister group, however, varied among different analyses and could not beascertained. The relationships of the new genus are therefore unclear, and because of this it is not assigned to any of thecurrently recognized subtribes. Eknomia can be diagnosed mainly by the anterior transverse carina of propodeum entirelyabsent; propodeum more or less uniformly strigate; clypeus almost entirely flattened; ovipositor stout, with compressed,minutely serrate flange at apex of dorsal valve, subapically crossed by a subvertical line; first metasomal spiracle placedat tergite midlength or nearly so; and hind margin of metanotum with tooth-like projections. The species E. nigra Santoset Aguiar, sp. nov., E. rubra Santos et Aguiar, sp. nov. and E. propodeator Santos et Aguiar, sp. nov. are described and illustrated. The genus is recorded from Colombia to southern Brazil.

Three new species of Russula collected from southern China are proposed based on morphological characters and phylogenetic analysis of internal transcribed spacer (ITS) sequences. Russula bubalina sp. nov. is characterized by cinnamon buff to pink pileus with striate margin, interveined and forked lamellae, basidiospores with warty ornamentations not forming reticulum, hymenial cystidia becoming brown in sulphovanillin (SV) and slender terminal cells in suprapellis. R. pseudobubalina sp. nov. is closely related to Russula bubalina in macro-morphology, but it can be recognized by its unforked lamellae, shorter cheilocystidia, bigger basidia and basidiospores with lower ornamentations. Russula subatropurpurea sp. nov. can be recognized by the purplish brown pileus, mild-tasted and white context changing to light purplish red with FeSO4, white and forking lamellae without lamellulae, long hymenial cystidia becoming brown in SV. Both morphological and phylogenetic analysis consistently confirmed the distinct positions of three new species in subg. Heterophyllidia subsection Heterophyllinae.

AbstractThree new species of Hysterothylacium Ward & Magath, 1917, including H. australe, H. kajikiae and H. brucei, from Australian marine fish are described and illustrated by light microscopy followed by genetic characterization of their first and second internal transcribed spacers (ITS-1 and ITS-2, respectively). This is the first study reporting ITS sequence data for adult Hysterothylacium spp. in Australia, which provides an insight into the identification of some of the Hysterothylacium larval types. Alignment of ITS sequences of these species with Hysterothylacium larval types previously reported in Australia showed that fourth-stage Hysterothylacium larval type XI from Seriola lalandi and third-stage Hysterothylacium larval type X from Sphyraene novae-hollandiae are identical with ITS sequences of H. australe, suggesting that these fish are natural intermediate/paratenic hosts of H. australe.

Phylogenetic analysis was used to evaluate evolutionary relationships within the Cambrian suborder Olenellina Walcott, 1890; special emphasis was placed on those taxa outside of the Olenelloidea. Fifty-seven exoskeletal characters were coded for 24 taxa within the Olenellina and two outgroups referable to the “fallotaspidoid” grade. The Olenelloidea, along with the genusGabriellusFritz, 1992, are the sister group of the Judomioidea Repina, 1979. The “Nevadioidea” Hupé, 1953 are a paraphyletic grade group. Four new genera are recognized,Plesionevadia, Cambroinyoella, Callavalonia, andSdzuyomia, and three new species are described,Nevadia fritzi, Cirquella nelsoni, andCambroinyoella wallacei. Phylogenetic parsimony analysis is also used to make predictions about the ancestral morphology of the Olenellina. This morphology most resembles the morphology found inPlesionevadiaandPseudojudomiaEgorova in Goryanskii and Egorova, 1964.

AbstractYoraperla Ricker, 1952 is revised and 4 nearctic and 3 oriental species are recognized. Three new species, X siletz, Y. han and Y. uchidai, are described and Y. nigrisoma (Banks, 1948) is removed from the synonymy of Y. brevis (Banks, 1907). Phylogenetic and zoogeographic analyses support the hypothesis of two disjunct clades isolated by an increase in sea level in the Bering Straits. The east Asian clade is consistently resolved with the two Korean species Y. han and Y. uchidai forming a sister group relationship apart from the Japanese species Y. uenoi, while resolution of the western North American clade is less secure. Yoraperla probably arose in the Sierra Nevada of North America and migrated to east Asia along an inland route including the Rocky Mts. Future collection and conservation suggestions are given.

Four species of Mycena possessing a colored lamellar are reported. Of these, Mycena entolomoides is described as new and is distinguished by an incarnate color of the whole lamellae, and M. citrinomarginata, M. purpureofusca, and M. strobilinoidea are recorded for the first time in China. A complete description, drawings and photographs of the morphological characters of M. entolomoides sp. nov. are accompanied by comparisons with closely related taxa. The three species newly recorded in China are considered in agreement with those species in Europe and North America. Phylogenetic analysis based on ITS sequences showed that M. entolomoides sp. nov. forms a monophyletic clade, well supported by maximum likelihood and Bayesian inference.

Three new phoretic mites from France and Gabon are described. Macrocheles lumareti sp. nov. (from France) was collected on Copris lunaris (Coleoptera, Scarabaeidae). Both M. bertrandi sp. nov. and M. ovoidalis sp. nov. (from Gabon) were collected on Stomoxys calcitrans (Diptera). On the basis of morphological characteristics, M. lumareti and M. bertrandi were identified as belonging to the M. glaber and M. muscadomesticae groups respectively. Genetic analyses using an ITS marker confirmed that M. lumareti belongs to the M. glaber-group s. str., more closely related to M. glaber than all other species. The analysis did not support M. bertrandi as a member of the M. muscaedomesticae group. The third species, M. ovoidalis, using both morphological and genetical markers, appeared clearly isolated from all other known Macrocheles species.

AbstractThree new species of Atla are described from calcareous rocks in northern Finland based on morphology and ITS sequences. All new species have dark brown spores but have smaller perithecia and spores than previously known brown-spored species of Atla. Atla tibelliorum sp. nov. resembles Sporodictyon arcticum, but has a dark brown exciple and larger spores. Atla oulankaensis sp. nov. and A. vitikainenii sp. nov. differ from A. alpina in the smaller perithecia and spores. Atla vitikainenii has an involucrellum often slightly diverging from the exciple. Atla oulankaensis is similar to A. vitikainenii, differing in slightly narrower spores and in having some involucrella incurving under the exciple or even enveloping the exciple. An unidentified ITS sequence from Canada obtained from GenBank most probably belongs to A. oulankaensis and another unidentified sequence from the USA to A. tibelliorum. The new results strengthen the conclusion that the genera of Atla and Sporodictyon cannot be separated by morphology alone. A key to all known species of Atla and Sporodictyon is provided.

Three new species of Tricholoma are described from Costa Rican montane forests with additional collections cited from the United States. The new species are Tricholoma felschii sp. nov., Tricholoma costaricense sp. nov. and Tricholoma atratum sp. nov. A discussion of Tricholoma luteomaculosum is also included. These taxa share morphological features of strong farinaceous odor and taste, pseudoparenchymatous pileal subcutis, and rugulose pileus at some stage of development. In addition, cheilocystidia occur in two of the taxa but not the third. Phylogenies are presented based on ITS sequences.
