为了确定在加州的蜜环菌物种的身份和分布，我们收集了589株管理区（城市景观，果园和葡萄园）和20个自然森林类型。从我们收集的分离物中，我们鉴定了A. mellea、黑果草A. gallica、细叶甲A. nabsnona和北美生物物种X（NABS X）。全州范围内的每一个物种的分布估计的基础上，他们收集的森林类型。只有A。mellea和A. gallica广泛分布于加州; nabsnona和NABS X似乎具有有限的范围。蜜环菌在该州大部分以开发为主的地区都很常见，如中央谷、旧金山弗朗西斯科湾区和洛杉矶。这是唯一的物种，除了一个单一的隔离的NABS X，隔离症状的主机，包括林木和种植的主机。蜜环菌在加州森林中确实会导致死亡，但大的疾病中心很少见。A.加州的gallica包括从我们的收集中鉴定的所有蜜环菌属物种的最大种类的森林类型。虽然它与A有许多共同的森林类型。mellea、黑果草A.高卢在发达地区极为罕见。A.加州的nabsnona似乎仅限于北方红杉林。NABS X仅在南部喀斯喀特山脉的高海拔红色和白色冷杉林中发现。
To determine the identity and distribution of Armillaria species in California, we collected 589 isolates from managed areas (urban landscapes, orchards, and vineyards) and 20 natural forest types. From our collection of isolates, we identified A. mellea, A. gallica, A. nabsnona, and North American biological species X (NABS X). State-wide ranges of each species were estimated based on distributions of forest types from which they were collected. Only A. mellea and A. gallica are widely-distributed in California; A. nabsnona and NABS X appear to have restricted ranges. Armillaria mellea is common in most regions of the state dominated by development, such as the Central Valley, the San Francisco Bay area, and Los Angeles. It was the only species, with the exception of a single isolate of NABS X, isolated from symptomatic hosts, including both forest trees and planted hosts. Armillaria mellea does cause mortality in California forests, but large disease centers are rare. The distribution of A. gallica in California includes the greatest variety of forest types of all Armillaria species identified from our collection. Although it shares many forest types in common with A. mellea, A. gallica is extremely rare in developed areas. The range of A. nabsnona in California appears to be restricted to northern redwood forests. NABS X was only identified in high elevation red and white fir forests of the southern Cascades.
