This fungus seems to be an exceptionally rare obligate symbiont of Retrophyllum rospigliosi (itself a red-listed conifer) in Venezuela. It has only been observed once, in 1963.
Venezuela (Mérida). The altitude of its only known station is 2200 m above sea level.
Known only from one collection, made in 1963. The absence of recent observations make it impossible to estimate extent of occurrence or area of occupation.
Population Trend: Uncertain
This species produces stromata and fruitbodies on dead portions of green leaves and stems of the conifer genus Retrophyllum. The life-cycle and biology have not been investigated, but disruption of colonized leaves is very localized, suggesting that the plant is well adapted to the presence of the fungus. There are no reports of the fungus causing harmful effects to the trees colonized. There is, for example, no evidence of premature leaf fall. The possibility that the fungus may have some beneficial effect on the tree has not been considered. Dispersal is by ascospores, possibly involving wind during humid spring weather, when the fertile extension expands and opens the upper chamber where dry masses of ascospores have accumulated. The ascospores bear a strong resemblance to the tetraradiate conidia of aquatic hyphomycetes, but the possibility that they too are adapted to specialized water dispersal has not been investigated. The only known associated organism is the conifer Retrophyllum rospigliosi (synonym Podocarpus rospigliosi), itself a threatened species.
Loss of habitat and (if more than one exists) fragmentation of populations.
A search is needed to try to rediscover this species.
Ex situ conservation. Not known to occur in any fungal culture collection. No genetic information about this species is stored in Genbank [accessed 1 March 2014].
