Dimorphism of sporangia in Albuginaceae (Chromista, Peronosporomycetes)
- 2006
-
Ingår i: Sydowia. - 0082-0598. ; 58:2, s. 178-190
-
Tidskriftsartikel (refereegranskat)abstract
- By using light- and scanning electron microscopy, the dimorphism of sporangia in Albuginales is demonstrated in 220 specimens of Albugo, Pustula and Wilsoniana, parasitic on plants belonging to 13 families. The presence of two kinds of sporangia is due to the sporangiogenesis and considered to be present in all representatives of the Albuginales. Primary and secondary sporangia are the term recommended to be used for these dissemination organs.

-
Ingår i: Sydowia. - 0082-0598. ; 73, s. 271-340
-
Tidskriftsartikel (refereegranskat)abstract
- In this 7th contribution to the Fungal Systematics and Evolution series published by Sydowia, the authors formally describe 14 species: Cantharomyces paschalis, Cryptandromyces pinguis, C. tricornis, Laboulbenia amblystomi (Laboulbeniales); Cortinarius squamosus, Entoloma brunneicoeruleum, E. callipygmaeum, E. minutigranulosum, E. perasprellum, E. pulchripes, E. tigrinum, E. timidum, E. violaceoserrulatum (Agaricales); and Suillus quercinus (Boletales). The following new country records are reported: Crepidotus malachioides from Italy, Leucoagaricus mucrocystis from French Guiana, Pluteus multiformis from Turkey (Agaricales); Herpomyces periplanetae from Benin, the D.R. Congo, and Togo (Herpomycetales); Melanustilospora ari from Pakistan (Urocystidales); Neopestalotiopsis clavispora causing fruit rot on Zizyphus mauritiana from India (Amphisphaeriales); and Phytopythium chamaehyphon and Pp. litorale from Brazil (Peronosporales). Finally, a new combination is proposed based on morphology, ecology, and phylogenetic analysis: Rhodocollybia asema (Agaricales).

Morphological characterisation and phylogenetic placement of the very rare species Psathyrella sulcatotuberculosa
- 2014
-
Ingår i: Sydowia. - 0082-0598. ; 66:2, s. 171-181
-
Tidskriftsartikel (refereegranskat)abstract
- A recent find of the very rare species Psathyrella sulcatotuberculosa (Psathyrellaceae) from Italy provided the authors with new data useful for improving the knowledge of an almost mysterious entity. Of this collection, a detailed morphological description, a statistical analysis of the spore size along with several photographs of the basidiomata in field and microscopical structures are provided and compared with the features of the type collection. Morphologically and/or molecularly allied species are discussed. Phylogenetic analysis of Psathyrellaceae based on sequence data from the nuclear ribosomal DNA internal transcribed region and partial large subunit placed P. sulcatotuberculosa in the P. candolleana clade with strong statistical support, together with P. candolleana, P. badiophylla, P. leucotephra and P. typhae. The result is also supported by morphology, where the species in the clade all lack pleurocystidia but have clavate, utriform and lageniform cheilocystidia with a rounded apex.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Fungal Systematics and Evolution (FUSE) is one of the journal series to address the“fusion”between morphological data and molecular phylogenetic data and to describe new fungal taxa and interesting observations. This paper is the 6th contribution in the FUSE series—presenting one new genus, twelve new species, twelve new country records, and three new combinations. The new genus is: Pseudozeugandromyces (Laboulbeniomycetes, Laboulbeniales). The new species are: Albatrellopsis flettioides from Pakistan, Aureoboletus garciae from Mexico, Entoloma canadense from Canada, E. frigidum from Sweden, E. porphyroleucum from Vietnam, Erythrophylloporus flammans from Vietnam, Marasmiellus boreoorientalis from Kamchatka Peninsula in the Russian Far East, Marasmiellus longistipes from Pakistan, Pseudozeugandromyces tachypori on Tachyporus pusillus (Coleoptera, Staphylinidae) from Belgium, Robillarda sohagensis from Egypt, Trechispora hondurensis from Honduras, and Tricholoma kena- nii from Turkey. The new records are: Arthrorhynchus eucampsipodae on Eucampsipoda africanum (Diptera, Nycteribiidae) from Rwanda and South Africa, and on Nycteribia vexata (Diptera, Nycteribiidae) from Bulgaria; A. nycteribiae on Eucampsipoda africanum from South Africa, on Penicillidia conspicua (Diptera, Nycteribiidae) from Bulgaria (the first undoubtful country record), and on Penicillidia pachymela from Tanzania; Calvatia lilacina from Pakistan; Entoloma shangdongense from Pakistan; Erysiphe quercicola on Ziziphus jujuba (Rosales, Rhamnaceae) and E. urticae on Urtica dioica (Rosales, Urticaceae) from Paki- stan; Fanniomyces ceratophorus on Fannia canicularis (Diptera, Faniidae) from the Netherlands; Marasmiellus biformis and M. subnudus from Pakistan; Morchella anatolica from Turkey; Ophiocordyceps ditmarii on Vespula vulgaris (Hymenoptera, Vespidae) from Austria; and Parvacoccum pini on Pinus cembra (Pinales, Pinaceae) from Austria. The new combinations are: Ap pendiculina gregaria, A. scaptomyzae, and Marasmiellus rodhallii. Analysis of an LSU dataset of Arthrorhynchus including isolates of A. eucampsipodae from Eucampsipoda africanum and Nycteribia spp. hosts, revealed that this taxon is a complex of multiple species segregated by host genus. Analysis of an SSU–LSU dataset of Laboulbeniomycetes sequences revealed support for the recognition of four monophyletic genera within Stigmatomyces sensu lato: Appendiculina, Fanniomyces, Gloeandromyces, and Stigmatomyces sensu stricto. Finally, phylogenetic analyses of Rhytismataceae based on ITS–LSU ribosomal DNA resulted in a close relationship of Parvacoccum pini with Coccomyces strobi.

Costa Rican dictyostelids, with notes on the taxonomy, phylogeny and ecology of Dictyostelium discoideum
- 2014
-
Ingår i: Sydowia. - 0082-0598. ; 66:1, s. 129-142
-
Tidskriftsartikel (refereegranskat)abstract
- In 1962 and then over the period of 1993-2001, samples of soil/litter for isolation of cellular slime molds (dictyostelids) were collected throughout Costa Rica. Collecting sites included examples of all major forest types found in the country and ranged in elevation from 10 to 3000 m. More than 3300 clones of dictyostelids were recovered from these samples. The clones included representatives of at least 24 described species along a number of isolates that do not conform closely to any known species and thus may be new to science. Greatest diversity was found in the montane/cloud forests, whereas the average number of clones per gram was highest in moist/wet forests. Distribution of species on a country-wide basis is compared with that of Mexico, another tropical country. In addition, phylogenetic analyses of 18S rDNA sequences were carried out on 12 different isolates of Dictyostelium discoideum, a predominantly temperate species that was recorded from both Costa Rica and Mexico.

Three new Entoloma species of the Cyanula clade from (sub)alpine habitats in Northern Norway and Sweden
- 2021
-
Ingår i: Sydowia. - 0082-0598. ; 73, s. 185-196
-
Tidskriftsartikel (refereegranskat)abstract
- Three Entoloma species belonging to the Cyanula clade from (middle-) northern boreal and alpine areas are described as new to science. Entoloma montanum, E. nordlandicum, and E. septentrionale, recorded from the Holmvassdalen area at Grane, North- ern Norway while E. montanum shows a wide distribution in Northern Scandinavia and the Caucasus. Entoloma nordlandicum, however, has recently been recorded also from the Netherlands. The three species are phylogenetically well defined based on analysis of the nrDNA ITS region and they are distant from their closest relatives. Morphological descriptions of each species are given, as well as their ecology, distribution and relationships towards similar species are discussed.

"The Mouldy Marshmallow" Amaurodon caeruleocaseus (Thelephorales, Basidiomycota) - the first stipitate species in the genus Amaurodon
- 2022
-
Ingår i: Sydowia. - 0082-0598. ; 74, s. 181-192
-
Tidskriftsartikel (refereegranskat)abstract
- Amaurodon (Thelephorales, Basidiomycota) constitutes a small but globally distributed genus in the order Thelephorales that is thought to be saprotrophic. Previously described species are soft and corticioid, with a smooth or hydnoid, blue to green hymenitun which turns green after drying and have spores that turn purple in KOH. Based on sequences from the nuclear rDNA regions ITS1-5.8S-ITS2 (ITS) and 28S Amaurodon caeruleocaseus is described from Western Australia a species that has all the morphological features common to the genus, with the interesting exception of forming a stipitate basidiome with a marshmallow-like consistency. Its closest relative is shown to be A. mustialaensis. The two species are unique within Thelephorales in having spores that appear smooth rather than ornamented illider a light microscope. A key to the genus Amaumdon is a Iso provided.
