Two new microfungi from Portugal: Magnohelicospora iberica gen. & sp nov and Phaeodactylium stadleri sp nov.

Two new microfungi are described and illustrated from a forest in Portugal. Magnohelicospora iberica gen. & sp. nov. is distinguished by polyblastic, integrated, sympodial conidiogenous cells and solitary, doliiform or conical, multi-euseptate, brown conidia tightly coiled in three planes. Phaeodactylium stadleri sp. nov. is characterized by obovoid to clavate, 0- to 2-septate, coarsely verruculose, subhyaline to very pale brown conidia. A key to accepted Phaeodactylium species is provided.
