Four Chinese new records of wood decaying fungi from karst areas in southwest of Guangxi
Morphological and molecular phylogenetic methods were employed to systematically identify wood-decaying fungi collected in karst areas of southwest Guangxi,and four newly recorded species of China,Rhizochaete radicata,Skeletocutis subalbomarginata,Fomitiporia ovoidospora and Megasporoporia inflata were reported.The basidiomata of R.radicata are membranous and cracked;the cystidia are fusiform and the spore is subovate to oval.The fresh fruiting bodies of S.subalbomarginata is reddish brown,with subfusiform and septate cystidium,and the spore is narrowly sausage-shaped.Basidiomata of F.ovoidospora is perennial,woody,with spindle-shaped cystidia and ovoid or rounded basidiospores.Basidiomata of M.inflata is annual and the skeletal hyphae become strongly swollen in KOH.ITS or nLSU sequences were phylogenetically analysed to provide molecular side witness of morphological identification.
