Observation 172217: Ascopolyporus Möller
When: 2014-05-19

Notes: These are a not uncommon sighting in (sub)tropical forest where bamboo is present. The fungus parasitizes white flies and scale insects which feed on the liquid-filled bamboo stalks. Once consumed by the fungus, the insect’s mouth parts are used as a straw through which the same fluids are consumed by the growing fungus, segueing from entomopathogenicity to phytopathogenicity over the course of its life cycle. Genera belonging to this group include Ascopolyporus, Hypocrella and Moelleriella, and are generally poorly understood. See the Neglected Genera of Plant-, Fungal- and Insect-Associated Fungi species list for more examples.

These were scattered but always solitary along young and old bamboo stalks (precise sp. unknown). Every specimen pictured was collected within a 10 meter radius of a single bamboo grove

Substrate: living bamboo

Habitat: West Andean cloud forest

Collectors: D. Newman & S. Boden

Collection #: RLC1398

looking forward to it.

M. aurantium

Danny, although i dont work with this group of fungi, i found one specimen, made a spore print and compared to Moller’s descripton, and im almost sure that it is a M. aurantium. Unfortunately i don’t have field photos, but instead i can upload photos of the dryed specimen and spores microscopy, soon.

do you have any collections that are definitely Mycocitrus that you have photographs and micrographs of to confirm? I would very much like to see comprehensive observations of fungi with this growth habit.

I think that Mycocitrus aurantium is another likely option for the orange ones, a species also decribed by Möller, that also grow in bamboo stalks.

Edit: Never mind… Specimens of Mycocitrus aurantium that i have found have a pure white interior… OR image 550109 is a young specimen.

One of the most interesting fungi

to date, Danny. Thanks for sharing!

current hypothesis:

these are all the same sp. (they most closely match A. polychrous in Möller’s 1901 color figure), but the little black, uniperitheciate things on the surface of the older stromata are a hyperparasite. it is most definitely not Engleromyces. fortunately, a specimen exists to enable further investigation.

Fascinating!

Really neat thanks for the info, great work. Found this on the net http://www.researchgate.net/...
Thanks Mark

An intriguing guess

Spores will have the final say, provided it’s mature. If Engleromyces, it is likely neither of the two described species.

Don’t necessarily think

I’m on the right track, but based on general growth form and substrate, have you considered Engleromyces?

I’ll split the observation later today.

Ascopolyporus and something else

The whitish fungus I think is Ascopolyporus. I collected it a lot in Madidi National Park, Bolivia, on bamboo. The yellow fungus, I am not sure. I would need to see the spores.
Beautiful fungi :)

Thanks, Martin

the spikey thing is called a (flower) frog. it’s used in floral arrangement. they’re sometimes sold with living bamboo at novelty shops. I got mine at a flea market. works wonderfully for macro staging.

Astonishing work!

Will look forward to your updates on this in the future! By the way, what spiky thing are you using to hold up your collections?
