A case of albinism in Inocybe rufuloides Bon. The authors present the study of a collection of albino specimens of Inocybe rufuloides found in Mallorca (Balearic Islands). The ITS molecular study of these samples confirms that it belongs to this species.
Agaricus macrolepis is here reported as new record in the Balearic Islands. A description macro and microscopic , pictures and ecology of samples found in Majorca island are afforded.
Se describen 3 especies nuevas del género Hodophilus, (H. fuscofoetens, H. hymenocystis y H. praecox) basadas en características morfológicas y moleculares, y se citan otras 7, todas ellas recolectadas en el norte de la península ibérica (País Vasco y Cantabria). Se aporta un estudio filogenético del material estudiado.
Contribution to the knowledge of the funga of the Balearic Islands (Spain). XXIV. 65 taxa of fungi found in the Balearic Islands are reported and discussed. After the information avalaible to us, 1 of them seems to be a new record for Spain: Asterodiscus tamaricis Voglmayr, Gardiennet & Jaklitsch., 13 of them seem to be new records for the Balearic Islands: Hysterobrevium mori (Schwein.) E.W.A. Boehm & C.L. Schoch, Hysterobrevium smilacis (Schwein.) E.W.A. Boehm & C.L.Schoch, Mytilinidion acicola G.Winter, Lamprospora dictydiola Boud. s.l., L.hispanica Benkert, L. miniata De Not. s.l., Octospora gyalectoides Svrèek & Kubička s.l., Paratricharina poiraultii (Boudier) Van Vooren, U. Lindemann, M. Vega, Ribes, Illescas & Matoèec, Leptosphaeria obesa (Durieu & Mont.) Sacc., Propolis leonis (Tul. & C. Tul.) Rehm, Hebeloma anthracophilum Maire, Hygrocybe subpapillata Kühner, Russula cistoadelpha M.M. Moser & Trimbach. Also 4 of them are new records in Mallorca island, 3 in Minorca island, 1 in Eivissa island and 1 in Formentera island. Remarks on their ecology, taxonomy and chorology are also included.
The taxonomic and genetic diversity of Cortinarius section Calochroi in one of the most biodiversity-rich regions in Europe, the Iberian Peninsula, was investigated through morphological and phylogenetic methods. This combined methodological approach allowed the identification of 15 known species and one new species, Cortinarius ortegae, which is described here. A dichotomous key is provided for field recognition of Calochroi species inhabiting different Iberian and Balearic Island woodlands. Polymorphism analyses within some studied species showed that the distribution of intraspecific lineages is dependent on geography and, in some cases, tree host. Furthermore, the dating analysis suggested that diversification within Calochroi started in the Pliocene and most of the current genetic diversity originated in the Pleistocene. This temporal scenario supports hypotheses in which climatic oscillations in the Quaternary may have been driving the evolution of this group of ectomycorrhizal fungi.
A study of the Genus Pholiotina Fayod in the Balearic Islands, based on previous citations and on the study of samples collected by the authors is presented. P. mediterranea is described as a new species and P. rugosa (Peck) Singer as a new record for the Balearic Islands. The macro amd microscopic features, molecular, biological, ecological and chorological data of booth species are also provided.
Se cita por primera vez para las Islas Baleares esta especie alóctona y de carácter marcádamente antropófilo de la que se conocen pocas citas en todo el estado español. Se incluye una completa descripción macro y microscópica de los ejemplares estudiados, acompañada de iconografías. Además se aportan comentarios taxonómicos y datos sobre su corología y ecología.
A systematic reevaluation of North American pyrophilous or “burn-loving” species of Pholiota is presented based on molecular and morphological examination of type and historical collections. Confusion surrounds application of the names P. brunnescens, P. carbonaria, P. castanea, P. fulvozonata, P. highlandensis, P. molesta, and P. subsaponacea, with multiple names applied to a single species and multiple species described more than once. Molecular annotations using nuc rDNA ITS1-5.8S-ITS2 (internal transcribed spacer [ITS] barcode) and RPB2 (RNA polymerase II second largest subunit) are used to aid in application of these names in a phylogenetic context. Based on ITS molecular annotations of 13 types, the following heterotypic synonymies are proposed: P. highlandensis (syn. P. carbonaria and P. fulvozonata); P. molesta (syn. P. subsaponacea); and P. brunnescens (syn. P. luteobadia). In addition, we observed that the species P. castanea, known previously only from the type collection in Tennessee, is found commonly on burned sites near the Gulf Coast and other southeast regions of the United States. Overall, the pyrophilous trait is evolutionarily derived in Pholiota. Endophytic and endolichenic stages were deduced for P. highlandensis, the most widely distributed of the pyrophilous Pholiota. As a result, we introduce the “body snatchers” hypothesis that explains the maintenance of some pyrophilous fungi in ecosystems as endophytes and/or endolichenic fungi. Photographs, taxonomic descriptions, and a dichotomous key to pyrophilous species of Pholiota that occur in North America are presented.
In this first contribution, the authors present the results of the study of samples of the
genus Conocybe collected in the area of the Balearic Islands (Spain), providing data on their macro- and microscopic features (accompanied by illustrations ), molecular biology, ecology and chorology of most of them. To the best of our knowledge, 3 appear to be new records for Spain, 7 for the Balearic Islands and 2 for the island of Eivissa. Additionally, some samples, object of previous publication, were also revised, both microscospically and molecularly, to confirm their previous determination or to rectify it and identify them correctly.
