“Piptoporus pseudobetulinus is a white rot and was taxonomically remote from the type of P. betulinus, because the last one is a brown rot. Polyporus pseudobetulinus has been proposed for the first time by Thorn et al. (1990). Later, De (1998) rename the specie Royoporus pseudobetulinus comb. nov., in the light of detailed studies on the morphological and anatomical characters. A recent phylogenic study (Yu-Cheng Dai et al. 2014) support the new combinaison of Polyporus pseudobetulinus as Favolus pseudobetulinus (Murashk. ex Pilat) Sotome & T. Hatt. (Sotome et al. 2011, 2013”) http://iucn.ekoo.se/iucn/species_view/447020

R. pseudobetulinus is a rare polypore anywhere and so, little information is known about its ecological requirements, biology or cultural characters. Decay of sapwood is a mottled white rot. The fruiting period begins in mid-May and extends to late June (Boulet 2003).

The few canadian collections of this specie were only recorded on dead balsam poplar (P. balsamifera L.) (Boulet 2003), and were not found on adjacent dead stems of trembling aspen (P. tremuloides Michx) nor large-toothed aspen (P. grandidentata Michx). Nevertheless, these later tree species are very common with a large distribution in North America (Ministère des Ressources naturelles 2013).

R. pseudobetulinus growth in wet and open stands of pure balsam poplar or in mixed woods with white elms, white birchs, basswood and northern white-cedars. This polypore growth usually on dead standing trees with bark (see photo 3), and occasionally on fallen trunks. The sporocarp growth sometimes in wounds , dead branch-stubs or exposed wood of living trees. Another feature of this fungus is that it often occurs quite low in the stem.

The habitat is different in Finland. Is seems this specie growth on tall, standing dead Populus tremula in dry open woods (Thorn et al. 1990).

Most collections are from the middle and southern zone (Canada) and hemiboreal zone (Russia), with a few from the northern boreal sub zone (Finland, Sweeden) and the temperate zone (Austria).
