Description
Individual shoots grow to a height of 5 millimeters, and up to 1 centimeter with mature fruit. Shoots emerge from both the cortex and needles of the host plant. Flowers are monoecious, and seed dispersal occurs in September.[4]
Distribution and host species
The species occurs in dry forests of the Himalayan mountains at an approximate altitude of 2500–3500 meters.[4][5] It has been reported in Nepal, India, Bhutan, and Pakistan. A. minutissimum infects the crowns of trees of all ages. It severely impacts the health of host-trees, and causes the loss of needles.[6] Although P. wallichiana is the primary host, it has been recorded to infect Pinus gerardiana in Pakistan. Unconfirmed reports show that it may also infect Abies pindrow and Cedrus deodara.[4]
It has been considered that there is potential for A. minutissimum to become an invasive species in Europe.[6]
