Abstracts |
Thelephoraceae are important contributors to the ectomycorrhizal diversity of temperate and boreal forests. Apart from Peudotomentella tristis and P. larsenii, P. humicola is now the third species of this genus, proven to form ectomycorrhizae. It forms brownish symbiotic organs when young that become dark brown to black at maturity#aa slightly greenish colour appears when treated with KOH. The plectenchymatous, mantle forms ring- to star-like surface patterns with a gelatinous matrix between the hyphae and lacks cystidia. Rhizomorphs are dark brown to black, characterized by nodia and conical side-branches and are tightly enveloped by a layer of thin, irregularly and repeatedly branched hyphae. The differences to the ectomycorrhizae of P. tristis and to those of Tomentella spp. with plectenchymatous mantles and lacking cystidia are discussed. |
