Pleomorphic Programming: Nuclear Traffic

Ok, I may suck at blogging but at least I didn't let this video get by without sharing


For more on this video head over to Phys.org and read the article: This fungus cell only looks like the 405.

Fungal Word Friday: Aspergilloma

An aspergilloma is a ball, or clump, comprised mostly of Aspergillus hyphae.

Histopathy of Aspergilloma

This is generally found in a body cavity such as the lung during a fungal infection.

The volva is a sheath around the stem base of some agarics.

Amanita ceasarea

It is especially well developed and recognizable among members of the Amanita genus.

Fungal Word Friday: Tempeh

Ok, sorry but my brain doesn't seem to be focusing today so Where I usually give a science word, today you get culinary genius; tempeh.

Sliced Tempeh

Tempeh is a food made by fermentation soybeans with the Mucoraceae fungus Rhizopus oligosporus and compressing it into a patty.
Preparing the patty for eating, it is sliced and then fried. It is eaten alone or really mixed into anything from chilies and stews to sandwiches and salads.

Fungal Word Friday: Spermagonium

The male gamete in rust fungi is a non-motile cell that is covered in a sticky substance that causes it to adhere to insects that com in contact with it. These gametes are produced within a cup or flask shaped structure called a spermagonium, which also produces a nectar to attract flies.

Pleomorphic Programming: Fungi Songs

Did you know people write songs about fungi? Well they do!

First up, here is a super catching song/video written by a teacher to help his 6th graders learn about fungi.

Next is a video some fella's did as a Biology project:

 

And lastly, if there is one song recently that has been know for being covered it is Gotye's "Somebody I used to know". So, I think I will
end with a cover of that song: I present the 2013 Science Parody of the year: Some Budding Yeast I Used to Grow:

The credit for these songs and their videos is purely that of their creators.

First Monday Mushroom: Lichen Agaric

This month we have an example of how topsy turvy taxonomy can be.Our mushroom is a small, moist, light brown-fading to yellow capped mushroom, with cream-yellow gills descending onto a light brownish stalk. The mushroom is found growing alongside lichens.

Lichen Agaric Lichenomphalia umbellifera

The reason this mushroom is an example how taxonomy can be rough in the fungi kingdom is all in the name. The Lichen agaric was once named among the Omphalina mushrooms. These mushrooms were given this name because of their small size and belly button like central dimple. This linked them to an older mushroom genus called Omphalia.; which was deemed as an illegitimate later homonym.  This means that several species which were categorized as Omphalina and Omphalia based on appearance had to be renamed because they did not truly belong there. The lichen agaric, once named Omphalina ericetorum, was one such mushroom. Its new and rightful name became Lichenomphalia umbellifera.

The key I am using is the  National Audubon Society Field Guide to North American Mushrooms and was published in 1985. Due to its publication date this key only gives the outdated name, but by cross referencing to newer keys and mushroom resources the history and newer identification becomes readily available.

Polypores are a group of fungi that form pores or tubes on their fruiting body for spore dispersion.

Fungal Word Friday: Conidiogenesis

Conidiogenesis is the technique utilized by conidial fungi to produce spores.

It falls into two basic patterns: Blastic conidiogenesis, where the condia develops before being separated off by a cross wall; and thallic conidiogenesis, in which a cross wall develops prior to the spore itself.

Fungal Word Friday: Muriform

Muriform refers to conidium that have septa both transversely and longitudinally.

Muriform conidia of Rhizocarpon subgeminatum

 This term derives from the resemblance to bricks in shape and arrangement.

All Your Amphibian Are Belong To Us

It is official, the chytrid Fungi have reached all three of the extant amphibian orders.

Chytrid fungi are the cause of global decimation in frogs and toads, as well as newts and salamanders. But, until now, the lesser known caecilians had managed to evade their mycelial grasp. That ends now!

Goodbye Mr. Bond Caecilian

A recent study released in the journal EcoHealth has found the first cases of chytridiomycosis in the legless amphibians. Unfortunately, EcoHealth is not a free journal so all I can link you to for the article is the article front page, provided by Springer. You can read the intro but for the full article you gots to have the monies: Batrachochytrium dendrobatidis Infection and Lethal Chytridiomycosis in Caecilian Amphibians (Gymnophiona). But there is also an piece in PsyOrg discussing the Journal article: Fatal fungus found in third major amphibian group, caecilians.

 The team of researchers conducted a field swab of over 200 specimens across 20 different species in five countries of Africa and South America and ran what amounted to the worlds largest caecilian PCR survey for the presence of Batrachohytrium dendrobatidis, which is the fungi generally refered to as the chytrid fungus. Their results? 58 specimens from Tanzania and Cameroon came back positive for it. That is over 25% of the total sample! Infection is a go!

But, wait you say, haven't some frogs shown a certain resistance to infection? Could, perhaps, caecilians face fungal morbidity sans mortality? Nope, the team managed to report the first lethal infections as well. Noting that while the degree of infection in the wild samples were not very high, they were at the same levels observed to cause death in Gaboon caecilians held in captivity.

So clearly, fungi have completed the dominance over the entire Amphibian Class. Who goes next? Bats? Bees?

Well, whichever group it is, I am sure we humans will have our hands full trying to prevent a complete fungal victory.

Fungal Word Friday: Dolipore Septum

We have talked about the septum before, a divider that grows within the hyphae of several filamentous fungi. But today I bring you a specific type of septum, the dolipore septum.

 

Dolipore Septum

This septum is found in basidiomycetes and the first thing you can tell by its name is that it has a pore, which means it is a partial septum. But what makes it unique is that at the end of each side (near the pore) the septum is swollen, this creates an elongated channel out of the typical pore opening.

So, in a simple one sentence definition:  A dolipore septum is a septum, charataristic of basidiomycetes, that enlarges near the pore in order to form an elongate channel.
