Some 4 years ago I found something similar and was tentatively identified as Cosmospora flavoviridis. Maybe I found the same species and was wondering if maybe there have been some update on the taxonomy of this group.

Macro-Data:
==========

Perithecium 0.15 - 0.25mm, bright red, (deep violet in KOH, yellow-amber in lactic acid) pyriform or subglobular with an ostiole which sometimes opens up to form a cupulate ascoma in mature specimens.  Wall approx 30-40um thick, composed of angular cells with thick walls. Fruiting bodies apparently have an orange substromatal layer growing over a black stroma of some pyrenomycete



Micro-data
=======
Asci cylindrical, 80-100um, do not stain very well in Congo red, very hyaline, thin bit rim thick walled with a pore-like opening, J-ve. 

Ascospores fusiform-ellipsoid to navicular (shape of the outline of a ship), with a thick central septum, spore wall constricted at this area, sometimes the two halves at an obtuse (160-170 degrees) angle hence the longitudinal axis is not straight, 14-18.3 (mean 16.0) x  5.4-6-7 (mean 6.1) with a Q of 2.3-3.3 (mean 2.7), smooth or minutely warted. Oil content amorphous or sometimes in two oil bodies, one per each side. 


If anyone wants a sample I have some which are nicely preserved... maybe a cryptic species that needs to be described, or just Cosmpospora flavoviridis (with a fusarium ananmorph if same as the one I found 4 years ago).
