The world’s largest Ostrya virginiana (hop-hornbeam/ironwood) 112 inches in circumference and 70 ft tall. It may not seem huge, but Ostrya are normally sub-canopy trees. Found in Hewen’s Creek Park in southern Ypsilanti Township.

I sometimes see a big hornbeam (Carpinus caroliniana) and I sometimes see a big hophornbeam (Ostrya virginiana). But I rarely see them side-by-side. That Ostrya is especially chonk! #thicktrunkthursday #Betulaceae #iamabotanist

Ostrya carpinifolia, die europäische Hopfenbuche. Gehört zu den Birkengewächsen und kommt aus Südeuropa. Gilt bei uns als Klima- und Zukunftsbaum. Die Fruchtstände erinnern an Hopfenfrüchte. Ihre rissige Borke beherbergt zahlreiche Insekten, worüber sich vor allem zahlreiche Vögel freuen.

Empfehlung für eine #klimaresiliente „fast“ heimische Baumart. Die #Hopfenbuche (Ostrya carpinifolia) wird bis ca. 15 Meter hoch und ist wie die Hainbuche kein Buchengewächs (Fagaceae), sondern gehört wie diese zu den Birkengewächsen (Betulaceae). Sie kommt „natürlich“ bis Norditalien vor.

Carpinus betulus supports c. 132 species of invert as larval host, many of which also use other members of the Betulaceae: Alnus, Betula, Corylus, Ostrya. Relationships are often signalled by specific epithets: carpini, alneti, betulae, coryli. [Reaction wood, best impression of Iggy Pop.]
timber of C. betulus very strong, but difficult to work because of cross grain, this reaction wood always reminds me of Iggy Pop

While going back for an interesting calicioid fungus on ironwood/Ostrya today I also noticed the elusive "ironwood chaga". I found this years ago and it has intrigued me since.
A black sclerotium of chaga growing out of a tree trunk with several headstones in the background A more distant view of the chaga on the ironwood. The bark is in vertical strips, and has blue-grey foliose lichens growing on it. a large maple is visible in the background a view of the inside of the chaga. it's a browish orange which has blackened externally with age

Ostrya virginiana is called Hophornbeam because of its fruits, which look like hops strung along the branches.
