ŠUTARA J., ŠPINAR P. (2006): Boletus kluzakii, a new species related to Boletus radicans. [Boletus kluzakii spec. nov., Boletus sect. Calopodes, Boletaceae, taxonomy, Czech Republic] Czech Mycology 58(1-2): 31-42 (published: 10th August, 2006)
abstract
A new species, Boletus kluzakii, which was found in southern Bohemia (Czech Republic), is described. Typical characters of this bolete are: pileus when young whitish or pallid, sometimes with a slight pinkish tint, then more or less rose-pink or purplish pink, at times even purple-reddish in some places; pileus surface conspicuously reddening when handled or bruised; hymenophore yellow, bluing when bruised; stipe yellow with a yellow reticulation; context under pileus cuticle red or purplish red but in other parts of the pileus and in upper half of the stipe pale yellowish or vivid yellow, turning blue when injured; taste bitter. Characters distinguishing Boletus kluzakii from Boletus radicans (the most closely related species) and from other boletes with a pinkish or reddish shade of pileus (Boletus regius, B. fuscoroseus, B. speciosus, B. pulchrotinctus, B. roseoolivaceus, B. roseopurpureus and B. pulchriceps) are discussed.
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.
ŠUTARA J. (2008): Xerocomus s. l. in the light of the present state of knowledge. [Boletaceae, Xerocomus, Xerocomellus, Hemileccinum, generic taxonomy, anatomy, histology] Czech Mycology 60(1): 29-62 (published: 4th July, 2008)
abstract
The definition of the generic limits of Xerocomus s. l. and particularly the delimitation of this genus from Boletus is very unclear and controversial. During his study of European species of the Boletaceae, the author has come to the conclusion that Xerocomus in a wide concept is a heterogeneous mixture of several groups of species. These groups are separated from each other by different anatomical and some other characters. Also recent molecular studies show that Xerocomus s. l. is not a monophyletic group. In agreement with these facts, the European species of Xerocomus s. l. whose anatomy was studied by the present author are here classified into the following, more distinctly delimited genera: Xerocomus s. str., Phylloporus, Xerocomellus gen. nov., Hemileccinum gen. nov. and Pseudoboletus.Boletus badius and Boletus moravicus, also often treated as species of Xerocomus, are retained for the present in the genus Boletus. The differences between Xerocomus s. str., Phylloporus, Xerocomellus, Hemileccinum, Pseudoboletus and Boletus (which is related to this group of genera) are discussed in detail. Two new genera, Xerocomellus and Hemileccinum, and necessary new combinations of species names are proposed.
