Interpretive Summary: Fungi in the ascomycetous order Hypocreales are of great importance to humanity in areas ranging from the cause of serious plant diseases to the production of new powerful antibiotics. In the last twenty years progress has been made toward understanding the characteristics of this group of fungi. The research reports on two species in this order that are new to science. They are described and illustrated in both their sexual and asexual states. This research allows others to identify these fungi.
Technical Abstract: Two new Ascomycetes, both classified in the Hypocreales, are described as Hypocrea cinereoflava and Endocreas simpsonii. Hypocrea cineroflava produces effused, grayish yellow stromata with immersed, KOH-perithecia. Its anamorph is Stilbella flavipes, which produces white to greenish synnemata covered with lobed conidiogenous cells. A mycelial synanamorph with some similarities to those in Trichoderma section Hypocreanum is also produced. Endocreas simpsonii produces immersed groups of perithecia with orange ostioles. Its anamorph does not correspond with any known species of Stilbella; it has whitish, smooth synnemata with monoverticillate conidiophore branching.
