Today I picked up a pebble on campus with a Verrucaria #lichen on it. Because I like pain and suffering I tried to ID it to species.
Tag along if you like. We will be using LGBI3(31) Verrucariales: Verrucariaceae

let me know what you think :) short tutorial behind the help button.
this would be to draw newbies in mainly, so they see how diverse life is.
at the moment, need to log in (top right), then change in settings.
Thallus without densely pigmented areas, not maritime
48>58>59
Thallus various ... involucrellum present, not parasitic
59>64>67
Average ascospore length higher, at least 12 µm, extreme lengths as low as 9 µm
67>75
75>80
Ascospores more than 3 µm diam. (often much more)
(diametre here ~6-9 µm)
80>81
Thallus not subgelatinous
81>89
Thallus in section not composed of goniocysts
89>92
Ascospores smaller, average length no more than 25 µm
92>98
98>99
Thallus various; perithecia smaller; terrestrial or freshwater habitats
99>100
... spore measurements (here it gets muddy)
100>101 rather than 104
Thallus various, but epinecral layer absent
101>102
102>103
Perithecia prominent, involucrellum well-developed, often conical; in terrestrial habitats
103>Verrucaria dolosa🎉
How does it hold up?
LGBI3 spores for V. dolosa vs. my measurement:
mean lgt 15.9 vs 15.96 µm
mean wdh 7.0 vs. 6,85 µm
