the older, better name is P. subhepatica, according to Dr. Karen Nakasone, to whom any collections of this sp. should be sent for analysis and comparison. She is actively researching Punctularia.

see conversation at Observation 198256. The broken bits of encrusted hyphae, lack of a distinct hymenium, and strongly truncated ends of the spores shown in these micrographs would seem to indicate this is asexual material.

The asexual characters of Punctularia atropurpurascens as described and illusratated by Elia Martini (https://www.aphyllo.net/spec.php?id=1141900), combined with those of these two descriptions appear to be a promising match for this material and a whole host of similar, mis- or unidentified observations on the site.

Chondrostereum purpureum????

probably a dumb idea, but could this be Chondrostereum purpureum?
did you smell it?
the spores look like conidia, not basidiospores.

crappy name change

there is only one species in Terana. I can’t get to the literature to see if Adans. designated a type species for his genus. Regardless, it’s a name change based on pretty tenuous grounds.

In any case, your fungus is not something I recognize, but definitely NOT T. caerulea or P. caeruleum. The lack of definitive microscopic characters is surprising for a corticioid fungus, which are usually loaded with characters. Oh well.

Terana caerulea is the new name for Pulcherricium caeruleum.

I dunno

Hi Alan. The fruiting body looks vaguely like Phanerochaete crassa, but I don’t see metuloid cystidia or the right color spores. I am unfamiliar with Terana caerulea. Sorry.
