Abstract:
The inclusion of the species of polypores with rose-colored context in the genus Fomitopsis is proposed in this study. Temperature responses demonstrated that these fungi can be placed in three groups according to their optimum temperature for growth: (1) Fungi with an optimum at 25 C, Fomitopsis rosea; (2) Fungi with an optimum at 28 C, Fomitopsis feei, Fomitopsis lilacino-gilva, Fomitopsis cajanderi, and Fomitopsis carnea; (3) Fungi with an optimum at 30-34 C, Fomitopsis dochmius, F. cajanderi, and Fomitopsis cupreo-rosea. Decay tests showed that Fomitopsis feei and Fomitopsis lilacino-gilva reported only on hardwoods are also capable of decaying conifers "in vitro", causing weight losses up to 40% after 20 weeks. It was confirmed that all these fungi were brown rotters. An heterothallic, bipolar behavior was demonstrated for F. feei and agreed with the behavior previously reported for two other members on this complex, F. rosea and F. cajanderi. Due to the failure of the other isolates to fruit in culture, their sexual behavior could not be determined. Monokaryotic x monokaryotic pairings and monokaryotic x dikaryotic pairings showed homogenic or heterogenic incompatibility between members of the same species or different species. Vegetative incompatibility was found when pairing heterokaryotic dikaryons of different isolates of the same species which demonstrated genetic diversity in the populations. Dikaryotization did not occur when heterokaryotic dikaryons of F. lilacino-gilva, F. dochmius, F. carnea, and F. cupreo-rosea were paired with monokaryons of F. feei, F. cajanderi, or F. rosea which supported the concept of genetically different species.
