Nevertheless, the upper surface in species belonging to the new genus Leiotrametes turned deep brown or even almost black with 5% KOH, but the selleck chemicals colour of the context did not show a strong reactivity and remained pale yellow. Indeed, this KOH reaction was already used to distinguish Leiotrametes lactinea (turning

to deep brown) from ‘Trametes’ modesta or T. supermodesta (becoming red to brownish) by Gomes-Silva et al. (2010). Biogeography Leiotrametes and Artolenzites are common in all tropical areas, some species, such as L. lactinea and A. elegans being apparently pantropical (Neotropics and New Caledonia). Nevertheless L. lactinea has been recently collected by Vlasák and Kout (2011) in Eastern USA (especially Florida) and interpreted as a recent colonization. Selleckchem EPZ 6438 According to Gilbertson and Ryvarden (1987), A. elegans is common in South Eastern USA. However, since Vlasák and Kout (2011) “were able to find only one specimen of this species

find more in ten year”, such a statement could result from a misidentification with either L. lactinea or T. gibbosa the intr0oductions of which could possibly be recent in the North American continent. Leiotrametes menziesii (= T. menziesii) is so far known from Paleotropical area (Ryvarden and Johansen 1980; Corner 1989) and is reported here from the Neotropics for the first time. Trametes and Pycnoporus are more widely distributed. Some species are commonly found in Northern temperate or Mediterranean areas, but they also

include common tropical species such as T. maxima, T. meyenii, T. villosa, P. sanguineus or P. puniceus. Finally Lenzites warnieri and Trametes ljubarskyi are mainly Mediterranean species. Taxonomy Genus Trametes Fr., Fl. Scand.: 339 (1836), emend. Synonyms : Lenzites Fr., Fl. Scand. : 339 (1836); Coriolus Quél., Enchir. Fung.: 175 (1886); Coriolopsis Murrill, Bull. Torrey Bot. Club 32: 358 (1905). Type species : Trametes suaveolens Fr. (Murrill 1905). Species studied: T. betulina (L.: Fr.) Pilát (lectotype of Lenzites), T. gibbosa (Pers.: Fr.) Fr., T. hirsuta (Wulfen: Clomifene Fr.) Pilát (lectotype of Coriolus), T. junipericola Manjón et al., T. maxima (Mont.) David & Rajchenberg, T. meyenii (Klotzsch) Lloyd, T. ochracea (Pers.: Fr.) Gilbertson & Ryvarden, T. polyzona (Pers.: Fr.) Corner (holotype of Coriolopsis), T. pubescens (Schum.: Fr.) Pilát, T. socotrana Cooke, T. suaveolens (L.: Fr.) Fr., T. versicolor (L.: Fr.) Lloyd and T. villosa (Swartz: Fr.) Kreisel. Observations: The main feature which could characterize this genus is certainly the pubescent to hirsute upper surface of the pileus in all species (Fig. 4a–c). Although T. suaveolens, T. ochracea and T. gibbosa are characterized by a glabrescent abhymenial surface, they are in fact tomentose at early stages of their development (Fig. 4c).
