Alcea Alcea Alcea is a genus of about 60 species of flowering plants in the mallow family Malvaceae, commonly known as the hollyhocks. They are native to Asia and Europe. The single species of hollyhock from the Western Hemisphere, the streambank wild hollyhock, belongs to a different genus. Hollyhocks are annual, biennial, or perennial plants usually taking an erect, unbranched form. The herbage usually has a coating of star-shaped hairs. The leaf blades are often lobed or toothed, and are borne on long petioles. The flowers may be solitary or arranged in fascicles or racemes. The notched petals are usually over
Clonostachys rosea f. rosea penetrate, and grow inside the hyphae and conidia of "B. cinerea". Nematodes are infected by "C. rosea" when the fungus' conidia attach to their cuticle and germinate, going on to produce germ tubes which penetrate the host's body and kill it. In 2008 an isolate of "Clonostachys rosea" (NRRL 50072) was identified as producing a series of volatile compounds that are similar to some existing fuels. However, the taxonomy of this isolate was later revised to "Ascocoryne sarcoides". Clonostachys rosea f. rosea Clonostachys rosea f. rosea, also known as Gliocladium roseum, is a species of fungus in the family Bionectriaceae.
