true puffball

Definition
Noun 1. A type of fungus: A "true puffball" is a specific kind of fungus belonging to the family Lycoperdaceae. Its defining characteristic is a round or pear-shaped fruiting body that, upon reaching maturity, releases a cloud of powdery spores through a pore or when it is disturbed.
Usage
- The term "true puffball" is used to distinguish these fungi from other similar-looking but unrelated organisms, such as earthstars or false puffballs.
- It is primarily a biological or mycological (fungus-studying) term.
- Example: "We found several true puffballs in the meadow after the rain."
Advanced Usage
- In scientific classification: The term specifies membership in the taxonomic family Lycoperdaceae. For example, "The genus contains some of the largest true puffballs."
Variants and Related Words
- Puffball (noun): A more common, general term for fungi with a similar spore-dispersal mechanism. Not all "puffballs" are "true puffballs" in the strict scientific sense.
- Lycoperdaceae (noun): The scientific family name for true puffballs.
Synonyms
- Puffball (in general, non-scientific usage)
Notes on Meaning
- The key distinction of a "true puffball" is its method of spore dispersal. When mature, the interior becomes a dry, powdery mass of spores. Applying pressure (e.g., from a raindrop, an animal, or a curious human) causes the puffball to "puff" out a visible cloud of spores through an opening at the top.
- It is contrasted with "false puffballs," which may look similar but belong to different fungal families and have different internal structures or spore dispersal methods.
Noun
- any of various fungi of the family Lycoperdaceae whose round fruiting body discharges a cloud of spores when mature
