#Ascospores are the result of the sexual reproduction of #Ascomycota #fungi, being single celled or #septate. There are different ways of #dispersal. One option is obligatory or accidental transport via animals, such as #mites. The photos show mating mites of #Histiostoma sp. seemingly covered with 4 chambered ascospores. J. Karakehian et al. (2021) studied "Methods for observing, culturing, and studying living ascospores".

A fungal plant pathogen discovered in the #Devonian Rhynie Chert: Christine Strullu-Derrien et al. https://www.nature.com/articles/s41467-023-43276-1
"One #fungal resident of the #RhynieChert, Paleopyrenomycites devonicus, stands out. Described as #Ascomycota, it colonized the ancient plant Asteroxylon mackiei. Yet, the precise role it played – as a saprotroph, parasite, or pathogen – remains a tantalizing mystery."
We invite you to imagine a world over 400 million years ago, a time when Life on Earth was vastly different from what we know today. The Rhynie Chert, an iconic geological site in Scotland, offers a captivating glimpse into this distant past, holding secrets of an ancient terrestrial environment.
Happy #FungiFriday
