Two new species of Cladorrhinum

Two new species of Cladorrhinum, C. flexuosurn and C. microsclerotigenum, are described and their sequences of the 5.8S and 28S ribosomal DNA and internal transcribed spacers 1 and 2 of the ribosomal RNA gene cluster analyzed. Cladorrhinum flexuosum, isolated from soil in Spain, forms fast-growing, dull yellow colonies, flexuous conidiophores and globose to dacryoid conidia. Cladorrhinum microsclerotigenum, isolated from Musa sp. in Turkey, strongly resembles Cladorrhinum phialophoroides in the production of abundant terminal phialides, ellipsoid conidia and microsclerotia in culture. It differs from C. phialophoroides in its ability to grow at 36 C and high number of intercalary phialides, which only infrequently occur in C. phialophoroides.
