Fomitiporia Murril
Fomitiporia Murril is characterized by pileate to resupinate basidiomata, hymenial setae present in some species, dextrinoid basidiospores, and a dimitic hyphal system through all the basidioma (Decock et al. 2007). The genus has about 40 species described, many of those have been collected on live tree hosts, suggesting some levels of host-specificity (Amalfi et al. 2012; Dai et al. 2008). Historically, due to low morphological variation, several taxa represent morphological complexes of cryptic species, thus the phylogenetic reconstructions based on molecular data have been playing a crucial role in the discovery of unknown lineages (Decock et al. 2007; Vlasák and Kout 2011). Neotropical region presents a high diversity unknown (Amalfi and Decock 2013; Amalfi et al. 2014), mainly because there aremany areas without records of collections. Two new pileate species of Fomitiporia from south Brazil are described in this study. The phylogenetic tree for Fomitiporia is presented in Fig. 1.
Fig. 1 Phylogram generated from Maximum Likelihood (RAxML) analysis based on combined nrLSU, nrITS, EF and RPB2 sequence data of Fomitiporia. Maximum Likelihood bootstrap support values greater than 70 % and Bayesian posterior probabilities (BPP) greater than 0.98 are indicated above and below the nodes (BS/BPP). In the BI analysis average standard deviation of split frequencies = 0.005 and the bootstopping criteria of RAxML indicated 204 pseudoreplications as sufficient to access the internal branch support. New taxa are in blue and species for which obtained sequences are based on type material have names in bold. The tree is rooted with Phellinus uncisetus.
