Spore morphology and its systematic implication in Pteris (Pteridaceae). [PDF]

open access: yesPLoS ONE, 2018
Pteris (Pteridaceae) spores are usually trilete and can be distinguished by the perine ornamentation. The systematic value of spore morphology in Pteris is unclear, especially based on the renewed infrageneric classification of Pteris.

Genetic Factors and Host Traits Predict Spore Morphology for a Butterfly Pathogen [PDF]

open access: yesInsects, 2013
Monarch butterflies (Danaus plexippus) throughout the world are commonly infected by the specialist pathogen Ophryocystis elektroscirrha (OE). This protozoan is transmitted when larvae ingest infectious stages (spores) scattered onto host plant leaves by

Adaptation of the spore discharge mechanism in the basidiomycota. [PDF]

open access: yesPLoS ONE, 2009
Spore discharge in the majority of the 30,000 described species of Basidiomycota is powered by the rapid motion of a fluid droplet, called Buller's drop, over the spore surface.

Do Fungal Spore Morphological Traits Correlate with Allergenicity?

open access: yesMycoAsia - Journal of Modern Mycology, 2022
Fungal spores, like pollen, are identified as sources of allergens, yet fungal spore morphology, unlike pollen morphology, has not been correlated with allergenicity.
