They are called volcanic bombs.
Large round tephra are called bombs, while streamlined tephra are known as lapilli.
A medium-sized tephra fragment is typically called lapilli. These fragments are between 2 and 64 mm in size and are formed during explosive volcanic eruptions.
Blocks is the name used for the biggest pieces of tephra. Tephra is produced by a volcanic eruption.
Medium-sized tephra consists of pyroclastic material that falls between fine ash and coarse lapilli in size. It typically ranges from 2 to 64 millimeters in diameter and is produced during explosive volcanic eruptions. Medium-sized tephra can pose hazards to aviation, infrastructure, and human health depending on the volcanic activity.
Volcanic ash, cinders, and bombs are called tephra.
Large round tephra are called bombs, while streamlined tephra are known as lapilli.
A medium-sized tephra fragment is typically called lapilli. These fragments are between 2 and 64 mm in size and are formed during explosive volcanic eruptions.
If you are referring to the crossword puzzle clue, a medium sized tephra is also known as lapilli.

Medium-sized tephra can pose hazards to aviation, infrastructure, and human health depending on the volcanic activity.
Volcanic ash, cinders, and bombs are called tephra.
The larger-sized tephra is known as volcanic bombs. These are ejected as incandescent lava fragments that solidify while flying through the air and can reach several meters in diameter. Volcanic bombs are usually formed during explosive eruptions at volcanoes.
King or Queen sized.
Tephra, the material ejected into the air during an explosive volcanic eruption, consists of molten lava materials such as pumice, cinders, and volcanic ash that have cooled and solidified as they fell through the air. Large tephra deposits form where the material lands and eventually become compacted into rock called volcanic tuff.
Volcanic airborne debris is classified as either solid (tephra, aka pyroclasts, including "volcanic bombs") or particulate (ash). Lava chunks ejected into the air around a vent is called "spatter."*When solids condense from gaseous pyroclastic flows, the rock material is called ignimbrite.
The smallest size of volcanic tephra is Ash, particles smaller than 2 mm (0.08 inches) in diameter.
Fine ash is considered the finest type of tephra. It consists of particles less than 2 mm in diameter and is typically produced during explosive volcanic eruptions. Fine ash can travel long distances and can pose a hazard to aviation and human health.
