JANDA V., KŘÍŽ M., HOLEC J. (2019): Addendum to the typification of Butyriboletus regius [epitype,lectotype,nomenclature,taxonomy,Czech Republic] Czech Mycology 71(1): 33-35 (published: 5th March, 2019)
abstract
An epitype is designated for Butyriboletus regius. The authors briefly explain this step.
JANDA V., KŘÍŽ M., KOLAŘÍK M. (2019): Butyriboletus regius and Butyriboletus fechtneri: typification of two well-known species [lectotype, epitype, nomenclature, taxonomy, Czech Republic] Czech Mycology 71(1): 1-32 (published: 2nd January, 2019)
abstract
The paper deals with type material of two species of the genus Butyriboletus, which were described from the Czech Republic, originally as Boletus regius (Krombholz 1983) and Boletus fechtneri (Velenovský 1922). For both species lectotypes are designated, for B. fechtneri also an epitype. The authors present macro- and microscopic descriptions of these species based on the study of rich material including collections from the area of the type localities. Characters distinguishing both species from similar taxa are discussed.
JANDA V., KŘÍŽ M., KONVALINKOVÁ T., BOROVIČKA J. (2017): Macroscopic variability of Rubroboletus legaliae with special regard to Boletus spinarii. [Boletus legaliae f. spinarii, ITS sequence data, neotype, epitype, Czech Republic] Czech Mycology 69(1): 31-50 (published: 12th May, 2017)
abstract
The paper deals with the macroscopic variability of Rubroboletus legaliae. A detailed macroscopic description of this species is presented, based on collections from the region of the type locality in Central Bohemia. An epitype is selected because of the age and insufficient representativeness of the holotype. The authors point out that Boletus spinarii, a species described by Hlaváček from South Bohemia as a member of the B. regius complex (genus Butyriboletus at present), is conspecific with the previously described Boletus legaliae (genus Rubroboletus at present); therefore the name B. spinarii is a synonymous name. The alleged distinguishing character of B. spinarii – orange, cinnabar to brick-red pores when young, soon changing colour to orange-yellow or yellow – is occasional according to our long-term field observations, caused possibly by external factors and not fixed within individual mycelia of R. legaliae. The taxonomic value of this deviation is not important enough to consider a separate taxon. Comparison of ITS rDNA sequences supports the conspecifity of both species. Although the name B. spinarii was validly published, the holotype was not deposited in the herbarium designated in the protologue. Therefore, a neotype is designated here.
JANDA V., KŘÍŽ M. (2016): Rubroboletus satanas f. crataegi, validly published name for xanthoid form of Rubroboletus satanas. [Boletus satanas, nomenclature, taxonomy] Czech Mycology 68(1): 109-110 (published: 6th June, 2016)
abstract
The name Rubroboletus is a validly published generic name for the group of boletes including Boletus satanas. Its xanthoid form, Boletus satanas f. crataegi, is validly transferred to the genus Rubroboletus with the aim of correcting two invalid earlier attempts.
KŘÍŽ M., JANDA V. (2016): First records of Tricholoma bresadolanum (Agaricales) in the Czech Republic. [Tricholomataceae, description, ecology, Bohemia, Moravia] Czech Mycology 68(1): 97-108 (published: 31st May, 2016)
abstract
The paper reports on the first collections of Tricholoma bresadolanum in the Czech Republic. The authors present a macro- and microscopic description based on a study of material collected at two localities in the Bohemian Karst Protected Landscape Area in Central Bohemia. The species was also documented from another two sites in Moravia. The characters distinguishing T. bresadolanum from similar species of the genus Tricholoma are discussed.
JANDA V., KŘÍŽ M., REJSEK J. (2014): Supplementary notes on Xerocomus chrysonemus (Boletaceae): bluing context and distribution in the Czech Republic. [Xerocomus chrysonemus, Boletaceae, distribution, ecology, bluing context, Czech Republic] Czech Mycology 66(2): 147-155 (published: 23rd December, 2014)
abstract
The paper summarises the current state of knowledge of the distribution and ecology of Xerocomus chrysonemus in the Czech Republic. The authors present information on newly discovered localities in the Czech Republic and a yet unobserved feature of the species – bluing of the context. A distribution map based on the collections from the Czech Republic is presented and features suitable for field identification are summarised, especially with regard to X. subtomentosus, which frequently occurs together with the species in question.
JANDA V., KŘÍŽ M., GRACA M. (2014): First records of Xerocomus silwoodensis (Boletaceae) in the Czech Republic. [Xerocomus silwoodensis, Boletaceae, description, ecology, Czech Republic] Czech Mycology 66(2): 135-146 (published: 23rd December, 2014)
abstract
The paper contains a report on the first collections of Xerocomus silwoodensis in the Czech Republic. The authors present a macro- and microscopic description of this species based on a study of material collected from one Bohemian and one Moravian locality. Characters distinguishing X. silwoodensis from related species of the genus Xerocomus Quél. s. str. (X. ferrugineus, X. subtomentosus, and X. chrysonemus) are discussed.
ŠUTARA J., JANDA V., KŘÍŽ M., GRACA M., KOLAŘÍK M. (2014): Contribution to the study of genus Boletus, section Appendiculati: Boletus roseogriseus sp. nov. and neotypification of Boletus fuscoroseus Smotl. [Boletus roseogriseus sp. nov., Boletus fuscoroseus, morphology, molecular phylogeny, neotypification, distribution] Czech Mycology 66(1): 1-37 (published: 4th June, 2014)
abstract
The paper deals with Boletus roseogriseus and Boletus fuscoroseus, two closely related species of the genus Boletus, section Appendiculati. B. roseogriseus is described as a new species based on a morphological and molecular study of collected material. B. fuscoroseus, validly published by Smotlacha in 1912, has been often incorrectly named Boletus pseudoregius. This name, however, does not have priority because B. pseudoregius was validly published as late as 1988. In order to contribute to clarification of some controversial questions concerning B. fuscoroseus, the authors have selected a neotype for this species. Descriptions of B. roseogriseus and B. fuscoroseus are accompanied by results of a molecular study (ITS and LSU rDNA sequences) and a discussion of characters distinguishing these species from other representatives of section Appendiculati.
JANDA V., KŘÍŽ M., REJSEK J. (2013): First records of Xerocomus chrysonemus (Boletaceae) in the Czech Republic. [Xerocomus chrysonemus, Boletaceae, description, ecology, Czech Republic] Czech Mycology 65(2): 157-169 (published: 20th December, 2013)
abstract
The paper details the first collections of Xerocomus chrysonemus in the Czech Republic. The authors present a macro- and microscopic description of this species based on the study of material collected at five different localities. Characters distinguishing X. chrysonemus from related species of the genus Xerocomus s. str. (X. ferrugineus, X. subtomentosus, and X. silwoodensis) are discussed. The Latin name X. chrysonemus is a combination of the words ‘chryso’ = golden and ‘nema’ = mycelium, which very accurately describes the characteristic feature of this species, the golden yellow mycelium at the base of stipe.
