'''Tower-caps''' are a type of mushroom-like [[subterranean]] [[tree]]. Once fully grown, they can be designated for [[wood cutting]] and produce tower-cap [[logs|log]]s. Tower-caps will grow ''only if'' you have discovered an [[underground]] [[river]] or [[underground pool]]. Such features can be located using the [[site finder]] and on the local view during embarkation, if the relevant [[init.txt|init]] and [[world generation]] parameters are set. 

In order to ''prevent'' a tower-cap from growing (which you will want to do to prevent tower caps from blocking drainage floodgates), you must lay down [[road]]s, construct [[floor]]s or designate [[stockpile]]s. Any of these designations or constructions will prevent tower-cap growth.

As with normal trees, they take about 1 and a half years to fully grow.

== Underground tree farms ==

# If an underground river or pool has been discovered, tower-caps will start spontaneously growing in ''[[Irrigation|muddied]]'' subterranean areas (rock or soil). Tower caps will also start growing in any subterranean soil, so long as that tile has ''either'' soil walls on the z-level directly beneath it (intact soil, not mined out), ''or'' there is a muddied tile within 2 tiles on the same z-level.  Muddied soil has a denser production than dry soil.  (Note: it is unconfirmed whether tower caps will appear throughout the map or only in the same biome that the underground water is in.  See talk page for details.)
# This basically means that if the underground area is irrigated, there is a '''much better chance''' of getting tower caps to grow there.
# The distance or [[path]] to the underground river does not matter. Simply discovering an underground pool or river is enough. (does not work if you use reveal.exe)
# It is thus possible to make a (big) safe underground chamber where your dwarves may harvest wood without exposing themselves to the dangers of the surface world.
# Harvesting tower caps '''will''' anger the elves just like normal wood harvesting.

To design a tower-cap "farm", refer also to the [[Irrigation#Easier.2C_safer_irrigation|irrigation]] article.

Beware that young tower caps, like young trees, are fragile and will be quickly killed if repeatedly walked upon.
