Sporomega/Colpoma on Cistus

Hi again


What about this Sporomega/Colpoma growing on dead wood of Cistus ladanifer lying on the ground at the SW Spain?


The ascospores are 1-septate with a gel seath and an apical globule. Paraphyses with conspicuous Vbs stained blue by Cresyl blue. No yellow KOH reaction or only greenish on the dark, marginal, elements. This collection agrees with Guy Garcia's GG 04040402 and GG 05041001 from 2004 and 2005 on Calluna and Castanaea wood. But my spores are only 1-septate (not 3-septate) and lacks de yellow KOH reaction (saids 'as some Mollisia species').


Do you now some news on this fungus?


Thanks again

Re : Sporomega/Colpoma on Cistus
Are images of Guy's collections accessible?  Sherwood described a species with 3-septate ascospores that, interestingly, form ascoconidia within the asci (Coccomyces tympanidiosporus) from Cistus wood.  It would be interesting to compare this to Guy's collections.

Hi Joey.


Guy's pics are here https://www.cubbyusercontent.com/pl/CC%2bAscomycota/_1354d48ffaad4b59bd3ffdbb35915d1f#CC%20Ascomycota/5f%20Rhytismatales-Triblidiales/Rhytismataceae/Sporomega/Garcia.


He has not seen (as me) any ascocomidia, but I will consult Sherwood's paper.


Thanks a lot
