It was growing mixed in with A great example is our own Calliergonella lindbergii (Hypnum organization. Ten years ago, Barbara lindbergii). Andreas proposed starting a group of people interested in bryophytes and lichens. The goals of this group were to provide an opportunity to better learn these unique plants and to add to the knowledge of their distributions in Ohio. As we all know, Barb’s idea was hugely successful and with her continuing hard work has grown into the Ohio Moss and Lichen Association.

He had found an interesting dimorphism,” perhaps it invokes images orange lichen, covered with apothecia. of 16th century Italian masterpieces of The lichen was found on aspen and he man and woman, serpent and apple. It is had tentatively identified it as the Poplar unlikely that you imagine male and Sunburst Lichen. female Marchantia, Sphaerocarpos or Solenostoma. Yet, another (as if there aren’t enough already) wondrous quality of liverworts is that some are sexually dimorphic. Xanthomendoza hasseana.

But, Stein while the production of antheridia and archegonia (structures where sperm and The numerous apothecia, absence of eggs are produced) certainly constitute soredia, and presence of rhizines rather differences between sexes, it is the than hapters confirms that Stanley’s secondary characteristics that are the identification is correct. This specimen focus of sexual dimorphism. Secondary remains growing in the park but Stanley characteristics in liverworts are traits later found other individuals, one of like size, color and hairiness that which was collected as a voucher seemingly have nothing directly to do specimen to officially verify the record. with the production of eggs or sperm. Nice work Stanley! - Ray Showman Liverworts that are sexually dimorphic in these secondary characteristics must also be dioicous (have sexes on separate 4 plants) rather than monoicous (with observed that females of Conocephalum sexes on the same plant). It is when the salebrosum smell spicier than males. sexes are separate that things get interesting. When plants are dioicous, Why these sex-specific traits exist is a the possibility for selection to act on question yet to be thoroughly answered. females and males differently sets the Are females usually larger because they stage for the evolution of sexual have to do all the work of supporting dimorphism.
