Ethan CrensonHello all, This was found last weekend on a hardw
asci 8-spored, up to 90 × 8?m, w/ weakly amyloid tip, ascoplasma dextrinoid1; paraphyses filiform with slightly enlarged apex, exceeding asci by 10-20?m; spores mostly still inside asci (immature?), those found in media broadly ellipsoid, roughened (?).2nd to last micrograph was taken of an unusual (sterile?) area of tissue, which had been a similar yellowish reddish brown as the other tissues, but turned a rich blue-green after being left on the slide for ~20-30 minutes.
Spores:
(8.5) 8.6 – 10.5 (12.1) × (4.1) 4.13 – 5.6 (5.8) µm
Q = (1.6) 1.63 – 2.4 ; N = 14
Me = 9.7 × 4.9 µm ; Qe = 2

NOTE: I cannot shrink my images down to 150KB to be uploaded here. they may be viewed at either of the two above links.
I guess it is Phaeohelotium imberbe but I can hardly see anything under the mic.
With drought-tolerant disocmycetes it is different, you can study them weeks and months later, but they grow exposed and are dry when it is sunny.
But you can see it this way: "vital charcaters", as I call them, are very valuable additional features and often even more valuable than what can be saved in a herbarium. But the taxonomy that we are doing based on morphology usually lacks aspects like cultural characters or DNA data which often give very unexpected insights in taxonomy. For instance, some species are collective species that can be divided only based on culture or sequencing. And herbarium material loses the latter option if older than 10-20 years and the former often within a few weeks....
