Gymnosporangium clavariiforme


''Gymnosporangium clavariiforme'' is a species of rust fungus which alternately infects Juniperus and hawthorns.
In junipers,the primary hosts, ''G. clavariiforme'' produces a set of orange tentacle-like spore tubes called telial horns. These horns expand and have a jelly like consistency when wet.〔SORTING OUT GYMNOSPORANGIUM SPECIES - The aecial stage, Field Mycology Volume 7(4), October 2006, Brand, Brand and Shattock.〕 The spores are released and travel on the wind until they infect a hawthorn tree.
On the secondary hosts, the fungus produces yellowish depressions on the leaves. It also infects the fruit, which grows whitish tubes like a Medusa head. These are the spore tubes. The spores must then infect a juniper to complete the life cycle.
The fungus does not cause serious damage to junipers, but hawthorns can suffer serious loss of haw production due to the effects of the fungus.
