One hundred fifty one specimens of Beauveria spp. from 19 different locations were collected from September 1 to August 31, 2002. Most of the isolates were identified as Beauveria. bassiana. Cordyceps staphylinidaecola collected from Mt. Obong in Chunchon City covered the host with mycelia which were produced 1 to 4 stromata along with asexual spores. The size of bright yellow ununiform stromata were about 45 mm and the head about $17mm{ imes}4mm$. Perithecia completely immersed were $530{sim}550{ imes}290{sim}300{mu}m$ in size and mainly scattered on the head. Ascospore produced in asci in the size of $400{sim}450{ imes}4{sim}5{mu}m$ developed thread-like secondary spores, which were directly separated into secondary conidial spores. Conidia produced at apical portion of synnemata were $2.6{sim}3.4{ imes}1.2{sim}1.9{mu}m$ in size. High density of mycelium was observed at $25^{circ}C$ ranged from pH 6.5 to 8.5 after 11 days of inoculation. It took 15 to 18 days after inoculation to fully grow on the medium mixed brown rice with pupa. Mycelium developed stromata on the medium 30 days after completion of mycelial growth, where perithecia were produced in 40 days.
