Fungi aren’t the only organisms that produce haustoria to infect plants. Meet Dodder, a parasitic plant that does not produce chlorophyll since it takes nutrients from other plants. Death Valley is very much alive!

As of today, how would you rate your level of support for President Trump? A. Very Strong Support (100%) B. Strong Support (75%) C. Moderate Support (50%) D. Limited Support (25%) E. No Support (0%)

@AnnaBellaPics Lovely. Could you send me the cultivar name? Thanks in advance!!

Lovely lavender pincushion blooms … a garden favorite💜 Wishing you all a happy Tuesday🌿 #flowers #gardening

On a scale of 1-10 how bad do you want to see Jack Smith testify in front of Congress???

#Rust on brown knapweed (#Centaurea jacea agg.) likely caused by #Puccinia jaceae, found today along the Ru de Gally (Villepreux, France) while collecting diseased plants to prepare for next weekend’s French Science Festival @FeteScience.

#Rust on maize (#Zea mays) caused by #Puccinia sorghi with abundant urediniospores (28-32 × 20-26 µm) and a few rare teliospores — here hyperparasitized by Sphaerellopsis sp. ; sampling by Laura Nunes 🙏 from @IdeevL field experiments (Gif-sur-Yvette, FR).

Happy birthday, George B. Cummins (1904-2007)! 🎂🍄🌿🍄🎂 Cummins was the 2nd Director of the @PurdueBPP Arthur #Fungarium (@PurdueAg), inaugural @MSAFungi Distinguished Mycologist in 1981, and last published at the age of 99. To celebrate, have a prolific day!

Arthur fungarium is the only specific rust collection located in West Lafayette, IN. It is the Mecca for all uredinologists around the world. The state of IN now has an updated rust checklist in celebration of the fungarium. mycokeys.pensoft.net/article/148853/

@bennyjohnson Okay… that makes sense considering Texas v. Johnson (1989).

🚨BREAKING: President Trump signs an Executive Order punishing people who burn the American flag with a 1-year jail sentence: "If you burn a flag, 1 year in jail, no exits and it goes on your record. You will see flag burning stop immediately."

@SFSHAMOUN @Plants_MDPI @MDPIOpenAccess Thank you Simon (@SFSHAMOUN ). It was a great project and I - we - hope the review will be helpful for those wishing to explore the geographic and taxonomic boundaries of Arceuthobium in North America. There remains a lot of work to be done! Hope all is well!

@Sck26C @Plants_MDPI @MDPIOpenAccess @Sck26C Dear Shawn, I commend you and bob for this interesting article on Dwarf Mistletoes of North America. Job very well done. Cheers

I am happy to present “Dwarf Mistletoes (Arceuthobium, Viscaceae) of North America: Classification Systems, Phylogenetic Relationships, and Taxonomic Characteristics.” mdpi.com/3389468 #mdpiplants via @Plants_MDPI, @MDPIOpenAccess. Dedicated to Delbert “Del” Wiens.

Fantastic diversity of shapes of #Puccinia graminis aecia, likely influenced by developmental stage, resistance level of #Berberis vulgaris, inoculum pressure, weather conditions at infection, and formae speciales (around Dijon, France). But can you identify the intruder? 🤔

#Rust on #Rosa spinosissima caused by #Phragmidium rosae-pimpinellifoliae, forming clusters of galled flower buds & stems, here just before becoming entirely powdery (Val Suzon, FR).
