About 3 inches in length.
Initially I thought this was some form of pollen body. After some research, I discovered the juniper tree is infected with the Cedar Apple Rust fungus.
The life cycle of cedar apple rust is quite complex, and as the name suggests involves both cedar (juniper) and apple trees as alternating hosts. www.urbanext.uiuc.edu/focus/cedarapplerust.html
See nebulagirl's photo of the fungal gall (minus the gelatinous yellow tendrils) here.
This is a set of photographs from the Lotus Development party celebrating 25 years since the company was founded in 1982.
I worked at Lotus from 1988 to 1993, at the height of popularity of the Lotus 1-2-3 spreadsheet application. During this same time, the product Lotus Notes, the first widely successful network based application, was launched.
Since then, 1-2-3 was eclipsed by Microsoft Excel (and more generally by the Microsoft Office Suite). Lotus Notes, however, found long term success as a groupware/collaboration application, now part of IBM.
There is an excellent history Lotus Notes here.
