on Asteraceae

gall

mycelium amphigenous, also on the stems, generally persistent. Appressoria nipple-shaped to lobed, mostly single. Conidia elliptic, formed in chains, without fibrosin bodies. The cleistothecia contain 5-25 asci, each with 2 spores. Appendages numerous, sub-equatorial, 0.5-2(4) x the diameter; they are mycelioid, mostly simple, septate, initially hyaline, (dark) brown ultimately.

This list is based on the book by Braun & Cook (2012a); older authors also mention Asteraceae outside of the Cichoreae, or even plants from other families. The occurrence on Bombycilaena erecta (“Micropus erectus”) and Tripolium, Astereaeae, and Silphium, Thelesperma, and Thymophylla (Heliantheae), as stated by Klenke & Scholler, therefore is somewhat questionable.
