Accessory fruit Accessory fruit An accessory fruit (sometimes called "false fruit", "spurious fruit", "pseudofruit", or "pseudocarp") is a fruit in which some of the flesh is derived not from the ovary but from some adjacent tissue exterior to the carpel. Examples of accessory tissue are the receptacle of the strawberry, pineapple, common fig, and mulberry, and the calyx of "Gaultheria procumbens" or "Syzygium jambos". Pomes, such as apples and pears, are also accessory fruits, with much of the fruit flesh derived from a hypanthium. Other example could be the "anthocarps" specific to the family Nyctaginaceae, where most of the fruit comes from
Boletellus ananas including "Pinus" and "Quercus" species in southeastern North America and Central America, "Quercus humboldtii" in Colombia, various Fagaceae and Dipterocarpaceae species in Malaysia, and "Leptospermum" and "Pinus" species in New Zealand. In Guyana, the humic deposits on "Dicymbe" trunks bearing "B. ananas" are consistently permeated with abundant ectomycorrhizas. The fungus was reported as forming mycorrhizal associations with eucalypts in Australia, based on fruit body association with trees. Its North American distribution encompasses a range extending north from North Carolina to Florida, west to Texas and south to Mexico, and Central America. In 2008, it was reported for the first time
